RTEMS Intel i386 Applications Supplement
Directives are the application's interface to the executive, and as such their execution times are critical in determining the performance of the application. For example, an application using a semaphore to protect a critical data structure should be aware of the time required to acquire and release a semaphore. In addition, the application designer can utilize the directive execution times to evaluate the performance of different synchronization and communication mechanisms.
The actual directive execution times are reported in the Timing Data chapter of this supplement.
