The hardware platform used to -gather the times is described to give the reader a better -understanding of each directive time provided. Also, provided -is a description of the interrupt latency and the context -switch times as they pertain to the i386 version of RTEMS. - -@section Hardware Platform - -All times reported except for the maximum period -interrupts are disabled by RTEMS were measured using a Force -Computers CPU386 board. The CPU386 is a 16 Mhz board with zero -wait state dynamic memory and an i80387 numeric coprocessor. -One of the count-down timers provided by a Motorola MC68901 was -used to measure elapsed time with one microsecond resolution. -All sources of hardware interrupts are disabled, although the -interrupt level of the i386 allows all interrupts. - -The maximum period interrupts are disabled was -measured by summing the number of CPU cycles required by each -assembly language instruction executed while interrupts were -disabled. Zero wait state memory was assumed. The total CPU -cycles executed with interrupts disabled, including the -instructions to disable and enable interrupts, was divided by 16 -to simulate a i386 executing at 16 Mhz. - -@section Interrupt Latency - -The maximum period with interrupts disabled within -RTEMS is less than 13.0 microseconds -including the instructions -which disable and re-enable interrupts. The time required for -the i386 to generate an interrupt using the int instruction, -vectoring to an interrupt handler, and for the RTEMS entry -overhead before invoking the user's interrupt handler are a -total of 12 microseconds. These combine to yield a worst case -interrupt latency of less -13.0 + 12 -microseconds. [NOTE: The -maximum period with interrupts disabled within RTEMS was last -calculated for Release 3.1.0.] - -It should be noted again that the maximum period with -interrupts disabled within RTEMS is hand-timed. The interrupt -vector and entry overhead time was generated on the Force -Computers CPU386 benchmark platform using the int instruction as -the interrupt source. - -@section Context Switch - -The RTEMS processor context switch time is 34 -microseconds on the Force Computers CPU386 benchmark platform. -This time represents the raw context switch time with no user -extensions configured. Additional execution time is required -when a TASK_SWITCH user extension is configured. The use of the -TASK_SWITCH extension is application dependent. Thus, its -execution time is not considered part of the base context switch -time. - -Since RTEMS was designed specifically for embedded -missile applications which are floating point intensive, the -executive is optimized to avoid unnecessarily saving and -restoring the state of the numeric coprocessor. The state of -the numeric coprocessor is only saved when a FLOATING_POINT task -is dispatched and that task was not the last task to utilize the -coprocessor. In a system with only one FLOATING_POINT task, the -state of the numeric coprocessor will never be saved or -restored. When the first FLOATING_POINT task is dispatched, -RTEMS does not need to save the current state of the numeric -coprocessor. - -The exact amount of time required to save and restore -floating point context is dependent on the state of the numeric -coprocessor. RTEMS places the coprocessor in the initialized -state when a task is started or restarted. Once the task has -utilized the coprocessor, it is in the idle state when floating -point instructions are not executing and the busy state when -floating point instructions are executing. The state of the -coprocessor is task specific. - -The following table summarizes the context switch -times for the Force Computers CPU386 benchmark platform: - -@c ****** This comment is here to remind you not to edit the timetbl.t -@c ****** in any directory but common. -@c -@c Time Table Template -@c -@c COPYRIGHT (c) 1988-1999. -@c On-Line Applications Research Corporation (OAR). -@c All rights reserved. -@c -@c $Id$ -@c - -@ifset use-tex -@sp 1 -@tex -\centerline{\vbox{\offinterlineskip\halign{ -\span\rtemstimetable -\rtemsonecase{No Floating Point Contexts}{34} -\rtemsdirective{Floating Point Contexts} -\rtemscase{restore first FP task}{57} -\rtemscase{save initialized, restore initialized}{59} -\rtemscase{save idle, restore initialized}{59} -\rtemscase{save idle, restore idle}{83} -\rtemsendtimetable -}}\hfil} -@end tex -@end ifset - -@ifset use-ascii -@ifinfo -@itemize @bullet -@item No Floating Point Contexts -@itemize - -@item only case: 34 -@end itemize -@item Floating Point Contexts -@itemize - -@item restore first FP task: 57 -@item save initialized, restore initialized: 59 -@item save idle, restore initialized: 59 -@item save idle, restore idle: 59 -@end itemize -@end itemize -@end ifinfo -@end ifset - -@ifset use-html -@html -

The information in -this chapter was obtained using Release 3.2.1. - -@section Introduction - -The timing data for the i960CA version of RTEMS is -provided along with the target dependent aspects concerning the -gathering of the timing data. The hardware platform used to -gather the times is described to give the reader a better -understanding of each directive time provided. Also, provided -is a description of the interrupt latency and the context -switch times as they pertain to the i960CA version of RTEMS. - -@section Hardware Platform - -All times reported except for the maximum period -interrupts are disabled by RTEMS were measured using a Cyclone -Microsystems CVME961 board. The CVME961 is a 33 Mhz board with -dynamic RAM which has two wait state dynamic memory (four CPU -cycles) for read accesses and one wait state (two CPU cycles) -for write accesses. The Z8536 on a SQUALL SQSIO4 mezzanine -board was used to measure elapsed time with one-half microsecond -resolution. All sources of hardware interrupts are disabled, -although the interrupt level of the i960CA allows all interrupts. - -The maximum interrupt disable period was measured by -summing the number of CPU cycles required by each assembly -language instruction executed while interrupts were disabled. -Zero wait state memory was assumed. The total CPU cycles -executed with interrupts disabled, including the instructions to -disable and enable interrupts, was divided by 33 to simulate a -i960CA executing at 33 Mhz with zero wait states. - -@section Interrupt Latency - -The maximum period with interrupts disabled within -RTEMS is less than -2.5 microseconds including the instructions -which disable and re-enable interrupts. The time required for -the i960CA to generate an interrupt using the sysctl -instruction, vectoring to an interrupt handler, and for the -RTEMS entry overhead before invoking the user's interrupt -handler are a total of 37 -microseconds. These combine to yield -a worst case interrupt latency of less than -2.5 + 37 -microseconds. [NOTE: The maximum period with interrupts -disabled within RTEMS was last calculated for Release -3.2.1.] - -It should be noted again that the maximum period with -interrupts disabled within RTEMS is hand-timed. The interrupt -vector and entry overhead time was generated on the Cyclone -CVME961 benchmark platform using the sysctl instruction as the -interrupt source. - -@section Context Switch - -The RTEMS processor context switch time is 1 -microseconds on the Cyclone CVME961 benchmark platform. This -time represents the raw context switch time with no user -extensions configured. Additional execution time is required -when a TSWITCH user extension is configured. The use of the -TSWITCH extension is application dependent. Thus, its execution -time is not considered part of the base context switch time. - -The CVME961 has no hardware floating point capability -and floating point tasks are not supported. - -The following table summarizes the context switch -times for the CVME961 benchmark platform: - -@c ****** This comment is here to remind you not to edit the timetbl.t -@c ****** in any directory but common. -@c -@c Time Table Template -@c -@c COPYRIGHT (c) 1988-1999. -@c On-Line Applications Research Corporation (OAR). -@c All rights reserved. -@c -@c $Id$ -@c - -@ifset use-tex -@sp 1 -@tex -\centerline{\vbox{\offinterlineskip\halign{ -\span\rtemstimetable -\rtemsonecase{No Floating Point Contexts}{1} -\rtemsdirective{Floating Point Contexts} -\rtemscase{restore first FP task}{2} -\rtemscase{save initialized, restore initialized}{3} -\rtemscase{save idle, restore initialized}{4} -\rtemscase{save idle, restore idle}{5} -\rtemsendtimetable -}}\hfil} -@end tex -@end ifset - -@ifset use-ascii -@ifinfo -@itemize @bullet -@item No Floating Point Contexts -@itemize - -@item only case: 1 -@end itemize -@item Floating Point Contexts -@itemize - -@item restore first FP task: 2 -@item save initialized, restore initialized: 3 -@item save idle, restore initialized: 4 -@item save idle, restore idle: 4 -@end itemize -@end itemize -@end ifinfo -@end ifset - -@ifset use-html -@html -

The hardware platform used to -gather the times is described to give the reader a better -understanding of each directive time provided. Also, provided -is a description of the interrupt latency and the context switch -times as they pertain to the MC68020 version of RTEMS. - -@section Hardware Platform - -All times reported except for the maximum period -interrupts are disabled by RTEMS were measured using a Motorola -MVME135 CPU board. The MVME135 is a 20Mhz board with one wait -state dynamic memory and a MC68881 numeric coprocessor. The -Zilog 8036 countdown timer on this board was used to measure -elapsed time with a one-half microsecond resolution. All -sources of hardware interrupts were disabled, although the -interrupt level of the MC68020 allows all interrupts. - -The maximum period interrupts are disabled was -measured by summing the number of CPU cycles required by each -assembly language instruction executed while interrupts were -disabled. The worst case times of the MC68020 microprocessor -were used for each instruction. Zero wait state memory was -assumed. The total CPU cycles executed with interrupts -disabled, including the instructions to disable and enable -interrupts, was divided by 20 to simulate a 20Mhz MC68020. It -should be noted that the worst case instruction times for the -MC68020 assume that the internal cache is disabled and that no -instructions overlap. - -@section Interrupt Latency - -The maximum period with interrupts disabled within -RTEMS is less than TBD -microseconds including the instructions -which disable and re-enable interrupts. The time required for -the MC68020 to vector an interrupt and for the RTEMS entry -overhead before invoking the user's interrupt handler are a -total of 9 -microseconds. These combine to yield a worst case -interrupt latency of less than -TBD + 9 -microseconds at 20Mhz. [NOTE: The maximum period with interrupts -disabled was last determined for Release -3.2.1.] - -It should be noted again that the maximum period with -interrupts disabled within RTEMS is hand-timed and based upon -worst case (i.e. CPU cache disabled and no instruction overlap) -times for a 20Mhz MC68020. The interrupt vector and entry -overhead time was generated on an MVME135 benchmark platform -using the Multiprocessing Communications registers to generate -as the interrupt source. - -@section Context Switch - -The RTEMS processor context switch time is 35 -microseconds on the MVME135 benchmark platform when no floating -point context is saved or restored. Additional execution time -is required when a TASK_SWITCH user extension is configured. -The use of the TASK_SWITCH extension is application dependent. -Thus, its execution time is not considered part of the raw -context switch time. - -Since RTEMS was designed specifically for embedded -missile applications which are floating point intensive, the -executive is optimized to avoid unnecessarily saving and -restoring the state of the numeric coprocessor. The state of -the numeric coprocessor is only saved when an FLOATING_POINT -task is dispatched and that task was not the last task to -utilize the coprocessor. In a system with only one -FLOATING_POINT task, the state of the numeric coprocessor will -never be saved or restored. When the first FLOATING_POINT task -is dispatched, RTEMS does not need to save the current state of -the numeric coprocessor. - -The exact amount of time required to save and restore -floating point context is dependent on whether an MC68881 or -MC68882 is being used as well as the state of the numeric -coprocessor. These numeric coprocessors define three operating -states: initialized, idle, and busy. RTEMS places the -coprocessor in the initialized state when a task is started or -restarted. Once the task has utilized the coprocessor, it is in -the idle state when floating point instructions are not -executing and the busy state when floating point instructions -are executing. The state of the coprocessor is task specific. - -The following table summarizes the context switch -times for the MVME135 benchmark platform: - -@c ****** This comment is here to remind you not to edit the timetbl.t -@c ****** in any directory but common. -@c -@c Time Table Template -@c -@c COPYRIGHT (c) 1988-1999. -@c On-Line Applications Research Corporation (OAR). -@c All rights reserved. -@c -@c $Id$ -@c - -@ifset use-tex -@sp 1 -@tex -\centerline{\vbox{\offinterlineskip\halign{ -\span\rtemstimetable -\rtemsonecase{No Floating Point Contexts}{35} -\rtemsdirective{Floating Point Contexts} -\rtemscase{restore first FP task}{39} -\rtemscase{save initialized, restore initialized}{66} -\rtemscase{save idle, restore initialized}{66} -\rtemscase{save idle, restore idle}{68} -\rtemsendtimetable -}}\hfil} -@end tex -@end ifset - -@ifset use-ascii -@ifinfo -@itemize @bullet -@item No Floating Point Contexts -@itemize - -@item only case: 35 -@end itemize -@item Floating Point Contexts -@itemize - -@item restore first FP task: 39 -@item save initialized, restore initialized: 66 -@item save idle, restore initialized: 66 -@item save idle, restore idle: 66 -@end itemize -@end itemize -@end ifinfo -@end ifset - -@ifset use-html -@html -

The hardware platform used to -gather the times is described to give the reader a better -understanding of each directive time provided. Also, provided -is a description of the interrupt latency and the context switch -times as they pertain to the XXX version of RTEMS. - -@section Hardware Platform - -All times reported except for the maximum period -interrupts are disabled by RTEMS were measured using a Motorola -BSP_FOR_TIMES CPU board. The BSP_FOR_TIMES is a 20Mhz board with one wait -state dynamic memory and a XXX numeric coprocessor. The -Zilog 8036 countdown timer on this board was used to measure -elapsed time with a one-half microsecond resolution. All -sources of hardware interrupts were disabled, although the -interrupt level of the XXX allows all interrupts. - -The maximum period interrupts are disabled was -measured by summing the number of CPU cycles required by each -assembly language instruction executed while interrupts were -disabled. The worst case times of the XXX microprocessor -were used for each instruction. Zero wait state memory was -assumed. The total CPU cycles executed with interrupts -disabled, including the instructions to disable and enable -interrupts, was divided by 20 to simulate a 20Mhz XXX. It -should be noted that the worst case instruction times for the -XXX assume that the internal cache is disabled and that no -instructions overlap. - -@section Interrupt Latency - -The maximum period with interrupts disabled within -RTEMS is less than TBD -microseconds including the instructions -which disable and re-enable interrupts. The time required for -the XXX to vector an interrupt and for the RTEMS entry -overhead before invoking the user's interrupt handler are a -total of 9 -microseconds. These combine to yield a worst case -interrupt latency of less than -TBD + 9 -microseconds at 20Mhz. [NOTE: The maximum period with interrupts -disabled was last determined for Release -4.0.0.] - -It should be noted again that the maximum period with -interrupts disabled within RTEMS is hand-timed and based upon -worst case (i.e. CPU cache disabled and no instruction overlap) -times for a 20Mhz XXX. The interrupt vector and entry -overhead time was generated on an BSP_FOR_TIMES benchmark platform -using the Multiprocessing Communications registers to generate -as the interrupt source. - -@section Context Switch - -The RTEMS processor context switch time is 35 -microseconds on the BSP_FOR_TIMES benchmark platform when no floating -point context is saved or restored. Additional execution time -is required when a TASK_SWITCH user extension is configured. -The use of the TASK_SWITCH extension is application dependent. -Thus, its execution time is not considered part of the raw -context switch time. - -Since RTEMS was designed specifically for embedded -missile applications which are floating point intensive, the -executive is optimized to avoid unnecessarily saving and -restoring the state of the numeric coprocessor. The state of -the numeric coprocessor is only saved when an FLOATING_POINT -task is dispatched and that task was not the last task to -utilize the coprocessor. In a system with only one -FLOATING_POINT task, the state of the numeric coprocessor will -never be saved or restored. When the first FLOATING_POINT task -is dispatched, RTEMS does not need to save the current state of -the numeric coprocessor. - -The exact amount of time required to save and restore -floating point context is dependent on whether an XXX or -XXX is being used as well as the state of the numeric -coprocessor. These numeric coprocessors define three operating -states: initialized, idle, and busy. RTEMS places the -coprocessor in the initialized state when a task is started or -restarted. Once the task has utilized the coprocessor, it is in -the idle state when floating point instructions are not -executing and the busy state when floating point instructions -are executing. The state of the coprocessor is task specific. - -The following table summarizes the context switch -times for the BSP_FOR_TIMES benchmark platform: - -@c ****** This comment is here to remind you not to edit the timetbl.t -@c ****** in any directory but common. -@c -@c Time Table Template -@c -@c COPYRIGHT (c) 1988-1999. -@c On-Line Applications Research Corporation (OAR). -@c All rights reserved. -@c -@c $Id$ -@c - -@ifset use-tex -@sp 1 -@tex -\centerline{\vbox{\offinterlineskip\halign{ -\span\rtemstimetable -\rtemsonecase{No Floating Point Contexts}{35} -\rtemsdirective{Floating Point Contexts} -\rtemscase{restore first FP task}{39} -\rtemscase{save initialized, restore initialized}{66} -\rtemscase{save idle, restore initialized}{66} -\rtemscase{save idle, restore idle}{68} -\rtemsendtimetable -}}\hfil} -@end tex -@end ifset - -@ifset use-ascii -@ifinfo -@itemize @bullet -@item No Floating Point Contexts -@itemize - -@item only case: 35 -@end itemize -@item Floating Point Contexts -@itemize - -@item restore first FP task: 39 -@item save initialized, restore initialized: 66 -@item save idle, restore initialized: 66 -@item save idle, restore idle: 66 -@end itemize -@end itemize -@end ifinfo -@end ifset - -@ifset use-html -@html -

Also, provided is a description of the interrupt -latency and the context switch times as they pertain to the -PowerPC version of RTEMS. - -@section Hardware Platform - -All times reported in this chapter were measured using a DMV177 board. -All data and code caching was disabled. This results in very deterministic -times which represent the worst possible performance. Many embedded -applications disable caching to insure that execution times are -repeatable. Moreover, the JTAG port on certain revisions of the PowerPC -603e does not operate properly if caching is enabled. Thus during -development and debug, caching must be off. - -The PowerPC decrementer register was was used to gather -all timing information. In the PowerPC architecture, -this register typically counts -something like CPU cycles or is a function of the clock -speed. On the PPC603e decrements once for every four (4) bus cycles. -On the DMV177, the bus operates at a clock speed of -33 Mhz. This result in a very accurate number since it is a function of the -microprocessor itself. Thus all measurements in this -chapter are reported as the actual number of decrementer -clicks reported. - -To convert the numbers reported to microseconds, one should -divide the number reported by 8.650752. This number was derived as -shown below: - -@example -((33 * 1048576) / 1000000) / 4 = 8.650752 -@end example - -All sources of hardware interrupts were disabled, -although traps were enabled and the interrupt level of the -PowerPC allows all interrupts. - -@section Interrupt Latency - -The maximum period with traps disabled or the -processor interrupt level set to it's highest value inside RTEMS -is less than TBD -microseconds including the instructions which -disable and re-enable interrupts. The time required for the -PowerPC to vector an interrupt and for the RTEMS entry overhead -before invoking the user's trap handler are a total of -202 -microseconds. These combine to yield a worst case interrupt -latency of less than TBD + -202 microseconds at -100.0 Mhz. -[NOTE: The maximum period with interrupts disabled was last -determined for Release 4.0.0-lmco.] - -The maximum period with interrupts disabled within -RTEMS is hand-timed with some assistance from the PowerPC simulator. -The maximum period with interrupts disabled with RTEMS has not -been calculated on this target. - -The interrupt vector and entry overhead time was -generated on the PSIM benchmark platform using the PowerPC's -decrementer register. This register was programmed to generate -an interrupt after one countdown. - -@section Context Switch - -The RTEMS processor context switch time is 585 -bus cycle on the DMV177 benchmark platform when no floating -point context is saved or restored. Additional execution time -is required when a TASK_SWITCH user extension is configured. -The use of the TASK_SWITCH extension is application dependent. -Thus, its execution time is not considered part of the raw -context switch time. - -Since RTEMS was designed specifically for embedded -missile applications which are floating point intensive, the -executive is optimized to avoid unnecessarily saving and -restoring the state of the numeric coprocessor. The state of -the numeric coprocessor is only saved when an FLOATING_POINT -task is dispatched and that task was not the last task to -utilize the coprocessor. In a system with only one -FLOATING_POINT task, the state of the numeric coprocessor will -never be saved or restored. When the first FLOATING_POINT task -is dispatched, RTEMS does not need to save the current state of -the numeric coprocessor. - -The following table summarizes the context switch -times for the DMV177 benchmark platform: - -@c ****** This comment is here to remind you not to edit the timetbl.t -@c ****** in any directory but common. -@c -@c Time Table Template -@c -@c COPYRIGHT (c) 1988-1999. -@c On-Line Applications Research Corporation (OAR). -@c All rights reserved. -@c -@c $Id$ -@c - -@ifset use-tex -@sp 1 -@tex -\centerline{\vbox{\offinterlineskip\halign{ -\span\rtemstimetable -\rtemsonecase{No Floating Point Contexts}{585} -\rtemsdirective{Floating Point Contexts} -\rtemscase{restore first FP task}{730} -\rtemscase{save initialized, restore initialized}{478} -\rtemscase{save idle, restore initialized}{825} -\rtemscase{save idle, restore idle}{478} -\rtemsendtimetable -}}\hfil} -@end tex -@end ifset - -@ifset use-ascii -@ifinfo -@itemize @bullet -@item No Floating Point Contexts -@itemize - -@item only case: 585 -@end itemize -@item Floating Point Contexts -@itemize - -@item restore first FP task: 730 -@item save initialized, restore initialized: 478 -@item save idle, restore initialized: 825 -@item save idle, restore idle: 825 -@end itemize -@end itemize -@end ifinfo -@end ifset - -@ifset use-html -@html -

Also, provided is a description of the interrupt -latency and the context switch times as they pertain to the -PowerPC version of RTEMS. - -@section Hardware Platform - -All times reported in this chapter were measured using the PowerPC -Instruction Simulator (PSIM). PSIM simulates a variety of PowerPC -6xx models with the PPC603e being used as the basis for the measurements -reported in this chapter. - -The PowerPC decrementer register was was used to gather -all timing information. In real hardware implementations -of the PowerPC architecture, this register would typically -count something like CPU cycles or be a function of the clock -speed. However, with PSIM each count of the decrementer register -represents an instruction. Thus all measurements in this -chapter are reported as the actual number of instructions -executed. All sources of hardware interrupts were disabled, -although traps were enabled and the interrupt level of the -PowerPC allows all interrupts. - -@section Interrupt Latency - -The maximum period with traps disabled or the -processor interrupt level set to it's highest value inside RTEMS -is less than TBD -microseconds including the instructions which -disable and re-enable interrupts. The time required for the -PowerPC to vector an interrupt and for the RTEMS entry overhead -before invoking the user's trap handler are a total of -61 -microseconds. These combine to yield a worst case interrupt -latency of less than TBD + -61 microseconds at -na Mhz. -[NOTE: The maximum period with interrupts disabled was last -determined for Release 4.0.0-lmco.] - -The maximum period with interrupts disabled within -RTEMS is hand-timed with some assistance from PSIM. The maximum -period with interrupts disabled with RTEMS occurs was not measured -on this target. - -The interrupt vector and entry overhead time was -generated on the PSIM benchmark platform using the PowerPC's -decrementer register. This register was programmed to generate -an interrupt after one countdown. - -@section Context Switch - -The RTEMS processor context switch time is 214 -instructions on the PSIM benchmark platform when no floating -point context is saved or restored. Additional execution time -is required when a TASK_SWITCH user extension is configured. -The use of the TASK_SWITCH extension is application dependent. -Thus, its execution time is not considered part of the raw -context switch time. - -Since RTEMS was designed specifically for embedded -missile applications which are floating point intensive, the -executive is optimized to avoid unnecessarily saving and -restoring the state of the numeric coprocessor. The state of -the numeric coprocessor is only saved when an FLOATING_POINT -task is dispatched and that task was not the last task to -utilize the coprocessor. In a system with only one -FLOATING_POINT task, the state of the numeric coprocessor will -never be saved or restored. When the first FLOATING_POINT task -is dispatched, RTEMS does not need to save the current state of -the numeric coprocessor. - -The following table summarizes the context switch -times for the PSIM benchmark platform: -@c ****** This comment is here to remind you not to edit the timetbl.t -@c ****** in any directory but common. -@c -@c Time Table Template -@c -@c COPYRIGHT (c) 1988-1999. -@c On-Line Applications Research Corporation (OAR). -@c All rights reserved. -@c -@c $Id$ -@c - -@ifset use-tex -@sp 1 -@tex -\centerline{\vbox{\offinterlineskip\halign{ -\span\rtemstimetable -\rtemsonecase{No Floating Point Contexts}{214} -\rtemsdirective{Floating Point Contexts} -\rtemscase{restore first FP task}{255} -\rtemscase{save initialized, restore initialized}{140} -\rtemscase{save idle, restore initialized}{140} -\rtemscase{save idle, restore idle}{290} -\rtemsendtimetable -}}\hfil} -@end tex -@end ifset - -@ifset use-ascii -@ifinfo -@itemize @bullet -@item No Floating Point Contexts -@itemize - -@item only case: 214 -@end itemize -@item Floating Point Contexts -@itemize - -@item restore first FP task: 255 -@item save initialized, restore initialized: 140 -@item save idle, restore initialized: 140 -@item save idle, restore idle: 140 -@end itemize -@end itemize -@end ifinfo -@end ifset - -@ifset use-html -@html -

The hardware platform used to -gather the times is described to give the reader a better -understanding of each directive time provided. Also, provided -is a description of the interrupt latency and the context switch -times as they pertain to the XXX version of RTEMS. - -@section Hardware Platform - -All times reported except for the maximum period -interrupts are disabled by RTEMS were measured using a Motorola -BSP_FOR_TIMES CPU board. The BSP_FOR_TIMES is a 20Mhz board with one wait -state dynamic memory and a XXX numeric coprocessor. The -Zilog 8036 countdown timer on this board was used to measure -elapsed time with a one-half microsecond resolution. All -sources of hardware interrupts were disabled, although the -interrupt level of the XXX allows all interrupts. - -The maximum period interrupts are disabled was -measured by summing the number of CPU cycles required by each -assembly language instruction executed while interrupts were -disabled. The worst case times of the XXX microprocessor -were used for each instruction. Zero wait state memory was -assumed. The total CPU cycles executed with interrupts -disabled, including the instructions to disable and enable -interrupts, was divided by 20 to simulate a 20Mhz XXX. It -should be noted that the worst case instruction times for the -XXX assume that the internal cache is disabled and that no -instructions overlap. - -@section Interrupt Latency - -The maximum period with interrupts disabled within -RTEMS is less than TBD -microseconds including the instructions -which disable and re-enable interrupts. The time required for -the XXX to vector an interrupt and for the RTEMS entry -overhead before invoking the user's interrupt handler are a -total of 9 -microseconds. These combine to yield a worst case -interrupt latency of less than -TBD + 9 -microseconds at 20Mhz. [NOTE: The maximum period with interrupts -disabled was last determined for Release -4.0.0.] - -It should be noted again that the maximum period with -interrupts disabled within RTEMS is hand-timed and based upon -worst case (i.e. CPU cache disabled and no instruction overlap) -times for a 20Mhz XXX. The interrupt vector and entry -overhead time was generated on an BSP_FOR_TIMES benchmark platform -using the Multiprocessing Communications registers to generate -as the interrupt source. - -@section Context Switch - -The RTEMS processor context switch time is 35 -microseconds on the BSP_FOR_TIMES benchmark platform when no floating -point context is saved or restored. Additional execution time -is required when a TASK_SWITCH user extension is configured. -The use of the TASK_SWITCH extension is application dependent. -Thus, its execution time is not considered part of the raw -context switch time. - -Since RTEMS was designed specifically for embedded -missile applications which are floating point intensive, the -executive is optimized to avoid unnecessarily saving and -restoring the state of the numeric coprocessor. The state of -the numeric coprocessor is only saved when an FLOATING_POINT -task is dispatched and that task was not the last task to -utilize the coprocessor. In a system with only one -FLOATING_POINT task, the state of the numeric coprocessor will -never be saved or restored. When the first FLOATING_POINT task -is dispatched, RTEMS does not need to save the current state of -the numeric coprocessor. - -The exact amount of time required to save and restore -floating point context is dependent on whether an XXX or -XXX is being used as well as the state of the numeric -coprocessor. These numeric coprocessors define three operating -states: initialized, idle, and busy. RTEMS places the -coprocessor in the initialized state when a task is started or -restarted. Once the task has utilized the coprocessor, it is in -the idle state when floating point instructions are not -executing and the busy state when floating point instructions -are executing. The state of the coprocessor is task specific. - -The following table summarizes the context switch -times for the BSP_FOR_TIMES benchmark platform: - -@c ****** This comment is here to remind you not to edit the timetbl.t -@c ****** in any directory but common. -@c -@c Time Table Template -@c -@c COPYRIGHT (c) 1988-1999. -@c On-Line Applications Research Corporation (OAR). -@c All rights reserved. -@c -@c $Id$ -@c - -@ifset use-tex -@sp 1 -@tex -\centerline{\vbox{\offinterlineskip\halign{ -\span\rtemstimetable -\rtemsonecase{No Floating Point Contexts}{35} -\rtemsdirective{Floating Point Contexts} -\rtemscase{restore first FP task}{39} -\rtemscase{save initialized, restore initialized}{66} -\rtemscase{save idle, restore initialized}{66} -\rtemscase{save idle, restore idle}{68} -\rtemsendtimetable -}}\hfil} -@end tex -@end ifset - -@ifset use-ascii -@ifinfo -@itemize @bullet -@item No Floating Point Contexts -@itemize - -@item only case: 35 -@end itemize -@item Floating Point Contexts -@itemize - -@item restore first FP task: 39 -@item save initialized, restore initialized: 66 -@item save idle, restore initialized: 66 -@item save idle, restore idle: 66 -@end itemize -@end itemize -@end ifinfo -@end ifset - -@ifset use-html -@html -

Also, provided is a description of the interrupt -latency and the context switch times as they pertain to the -SPARC version of RTEMS. - -@section Hardware Platform - -All times reported in this chapter were measured -using the SPARC Instruction Simulator (SIS) developed by the -European Space Agency. SIS simulates the ERC32 -- a custom low -power implementation combining the Cypress 90C601 integer unit, -the Cypress 90C602 floating point unit, and a number of -peripherals such as counter timers, interrupt controller and a -memory controller. - -For the RTEMS tests, SIS is configured with the -following characteristics: - -@itemize @bullet -@item 15 Mhz clock speed - -@item 0 wait states for PROM accesses - -@item 0 wait states for RAM accesses -@end itemize - -The ERC32's General Purpose Timer was used to gather -all timing information. This timer was programmed to operate -with one microsecond accuracy. All sources of hardware -interrupts were disabled, although traps were enabled and the -interrupt level of the SPARC allows all interrupts. - -@section Interrupt Latency - -The maximum period with traps disabled or the -processor interrupt level set to it's highest value inside RTEMS -is less than TBD -microseconds including the instructions which -disable and re-enable interrupts. The time required for the -ERC32 to vector an interrupt and for the RTEMS entry overhead -before invoking the user's trap handler are a total of -8 -microseconds. These combine to yield a worst case interrupt -latency of less than TBD + -8 microseconds at -15.0 Mhz. -[NOTE: The maximum period with interrupts disabled was last -determined for Release 4.2.0-prerelease.] - -The maximum period with interrupts disabled within -RTEMS is hand-timed with some assistance from SIS. The maximum -period with interrupts disabled with RTEMS occurs during a -context switch when traps are disabled to flush all the register -windows to memory. The length of time spent flushing the -register windows varies based on the number of windows which -must be flushed. Based on the information reported by SIS, it -takes from 4.0 to 18.0 microseconds (37 to 122 instructions) to -flush the register windows. It takes approximately 41 CPU -cycles (2.73 microseconds) to flush each register window set to -memory. The register window flush operation is heavily memory -bound. - -[NOTE: All traps are disabled during the register -window flush thus disabling both software generate traps and -external interrupts. During a normal RTEMS critical section, -the processor interrupt level (pil) is raised to level 15 and -traps are left enabled. The longest path for a normal critical -section within RTEMS is less than 50 instructions.] - -The interrupt vector and entry overhead time was -generated on the SIS benchmark platform using the ERC32's -ability to forcibly generate an arbitrary interrupt as the -source of the "benchmark" interrupt. - -@section Context Switch - -The RTEMS processor context switch time is 10 -microseconds on the SIS benchmark platform when no floating -point context is saved or restored. Additional execution time -is required when a TASK_SWITCH user extension is configured. -The use of the TASK_SWITCH extension is application dependent. -Thus, its execution time is not considered part of the raw -context switch time. - -Since RTEMS was designed specifically for embedded -missile applications which are floating point intensive, the -executive is optimized to avoid unnecessarily saving and -restoring the state of the numeric coprocessor. The state of -the numeric coprocessor is only saved when an FLOATING_POINT -task is dispatched and that task was not the last task to -utilize the coprocessor. In a system with only one -FLOATING_POINT task, the state of the numeric coprocessor will -never be saved or restored. When the first FLOATING_POINT task -is dispatched, RTEMS does not need to save the current state of -the numeric coprocessor. - -The following table summarizes the context switch -times for the ERC32 benchmark platform: - -@c ****** This comment is here to remind you not to edit the timetbl.t -@c ****** in any directory but common. -@c -@c Time Table Template -@c -@c COPYRIGHT (c) 1988-1999. -@c On-Line Applications Research Corporation (OAR). -@c All rights reserved. -@c -@c $Id$ -@c - -@ifset use-tex -@sp 1 -@tex -\centerline{\vbox{\offinterlineskip\halign{ -\span\rtemstimetable -\rtemsonecase{No Floating Point Contexts}{21} -\rtemsdirective{Floating Point Contexts} -\rtemscase{restore first FP task}{26} -\rtemscase{save initialized, restore initialized}{24} -\rtemscase{save idle, restore initialized}{23} -\rtemscase{save idle, restore idle}{33} -\rtemsendtimetable -}}\hfil} -@end tex -@end ifset - -@ifset use-ascii -@ifinfo -@itemize @bullet -@item No Floating Point Contexts -@itemize - -@item only case: 21 -@end itemize -@item Floating Point Contexts -@itemize - -@item restore first FP task: 26 -@item save initialized, restore initialized: 24 -@item save idle, restore initialized: 23 -@item save idle, restore idle: 23 -@end itemize -@end itemize -@end ifinfo -@end ifset - -@ifset use-html -@html -
