Note that in the above command, the
–W
parameter indicates “write only”. Also
–R
can be
entered for read-only. If neither is entered, then the test assumes both read and write.
Also note in the above command that “performance measurement” has been specified using the
-p
option; in this case, specifically, the
–pt
option, which measures “transfer time only”,
excluding any intermediate software functions such as data preparation, error checking, etc.
Figure 4-10 below is a screen capture of a successful random block test of onchip shared
memory (i.e. MCSM, or multicore shared memory) for 32 cores, using SigC667x hardware, by
executing the following command:
#./memTest –cSIGC66XX –B0x100000 –pt –P –r –m0xffffffff –Mos –n10
