They measure +the execution time for a directive (under various circumstances) +from the time RTEMS is entered until it is executed. Where possible, +the time is the average of at least 100 invocations of the directive. + +The accuracy of the times reported by these benchmarks is very dependent +on the resolution of the timer being used. It is also important to +insure that all sources of hardware interrupts are disabled during +execution of the tests. This insures that the directive time reported +does not include any interrupt time. + |
