Kernel Real-time Characterization
Alarm latency [many threads]
This test attempts to measure the latency in calling an alarm callback function. The time from the clock inter-
rupt until the alarm function is called is measured. In this test, there are a number of threads which are running
when the clock interrupt occurs. They are simply passing back and forth by way of the
cyg_thread_yield()
call. The purpose of this test is to measure the variations in the latency when there are many executing threads.
