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 -
