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 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
