| 5 | This directory contains the RTEMS Timing Test Suite. |
---|
| 6 | The tests in this directory are used to measure the execution |
---|
| 7 | time of RTEMS directive and some critical internal functions. |
---|
| 8 | The results of these test are reported in the Fact Sheets |
---|
| 9 | and Supplental Manuals. |

---|
| 11 | These tests attempt to benchmark RTEMS as the user would. They measure |
---|
| 12 | the execution time for a directive (under various circumstances) |
---|
| 13 | from the time RTEMS is entered until it is executed. Where possible, |
---|
| 14 | the time is the average of at least 100 invocations of the directive. |
---|
| 15 | |
---|
| 16 | The accuracy of the times reported by these benchmarks is very dependent |
---|
| 17 | on the resolution of the timer being used. It is also important to |
---|
| 18 | insure that all sources of hardware interrupts are disabled during |
---|
| 19 | execution of the tests. This insures that the directive time reported |
---|
| 20 | does not include any interrupt time. |
