eCOS Kernel Timings
Note: all times are in microseconds (.000001) unless otherwise stated
 
Reading the hardware clock takes 0 'ticks' overhead
... this value will be factored out of all other measurements
Clock interrupt took   14.46 microseconds (30 raw clock ticks)
 
Testing parameters:
   Clock samples:          32
   Threads:                24
   Thread switches:       128
   Mutexes:                32
   Mailboxes:              32
   Semaphores:             32
   Scheduler operations:  128
   Counters:               32
