-/* timer.c
- *
- * This file manages the benchmark timer used by the RTEMS Timing Test
- * Suite. Each measured time period is demarcated by calls to
- * Timer_initialize() and Read_timer(). Read_timer() usually returns
- * the number of microseconds since Timer_initialize() exitted.
- *
- * NOTE: It is important that the timer start/stop overhead be
- * determined when porting or modifying this code.

- * If required this ISR is used to bump a count of interval "overflow"
- * interrupts which have occurred since the timer was started. The
- * number of overflows is taken into account in the Read_timer()
- * routine if necessary.
- *
- * To reduce overhead this is best to be the "rawest" hardware interupt
- * handler you can write. This should be the only interrupt which can
- * occur during the measured time period.

- * NOTE: This file is USUALLY in assembly and is LEAN AND MEAN.
- * Any code in this isr is pure overhead which can perturb
- * the accuracy of the Timing Test Suite.
