#
#  Timing Test Suite Results for the NO_BSP
#
#  NOTE: This is just a template.  The times are irrelevant since this BSP
#        can only be compiled -- not executed.

# @(#)times        08/01/96     1.4

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
