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 -
