- *
- * File: @ref rt_test_sequence_013.c
- *
- * <h2>Description</h2>
- * This module implements a series of system benchmarks. The benchmarks
- * are useful as a stress test and as a reference when comparing
- * ChibiOS/RT with similar systems.<br> Objective of the test sequence
- * is to provide a performance index for the most critical system
- * subsystems. The performance numbers allow to discover performance
- * regressions between successive ChibiOS/RT releases.
