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 -
