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