# Timing Test Suite Results for the NO_BSP

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: Algorithmics P4000i
CPU: IDT 4650
Clock Speed: 100MHz
Memory Configuration: SRAM, DRAM, cache, etc
Wait States:
Times Reported in: cycles
Timer Source: on-CPU cycle counter
