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 -
