Your formula wouldn't account for cases where some instructions are in parallel,
stalled due to external mem access, etc.

The way I usually do it is to relate processing time to input data. For example if
an input data frame arrives every 1 msec, and it takes the DSP 0.6 msec to process,
and TI rates the part at 4000 MIPS, then the algorithm is using 2400 MIPS. That
method is easy, and does offer the advantage of giving you a feel for the amount of
"overhead" remaining, but it still suffers from the problem of not really knowing how
many actual instructions are being executed.

If CCS could count the instructions, subtract out stalls, etc. then you could get a
more accurate figure.

Hello,

Does somebody has Codegen tools v4.32 for C6000 (I believe it is in CCS V2).

Could you send the build and link tools to me?

Thanks Start a New Thread

Hi everybody,

I have to calculate MIPS taken for my code. To calculate MIPS, I have a
formula ==> MIPS = (Total num of cycles/Total num of
Instructions)*CPU_Freq.

If the formula is right, then, with the help of profiling in CCS, I can
find the cycles taken, but what about the instructions, should I do
manually??

Or, is there any way to find it out during profiling itself.

Waiting for your replies........

Regards,

Narendra
