NOTE:  To obtain the execution time in microseconds, divide the number of
       cycles by the clock speed.  For example, if rtems_semaphore create 
       is reported to be 1164 cycles, then at 66 Mhz it takes 17.64 
       microseconds or 8.75 microseconds at 133 Mhz.

Board:                PC/AT clone
CPU:                  Intel Pentium
Clock Speed:          66 Mhz
Memory Configuration: DRAM w/512 Kb cache
Wait States:          unknown

Times Reported in:    cycles
Timer Source:         on-CPU cycle counter

Column A:             3.5.1 pre-release
Column Y:             unused
