Finding CPU Cycles

Other Parts Discussed in Thread: TMS320F2812

Hi,

I am using TMS320F2812. Can someone please guide me where I can find information about how many CPU cycles does it take for addition and multiplication instructions?

Thanks,

Darshana

Hi,

You could use profiling instrumentation mentioned in this link : http://processors.wiki.ti.com/index.php/Profiling_on_C28x_Targets

Hi Radhesh,

Thanks for the reply. That doesn't answer my question though. I need the statistics on the CPU cycles used up for addition and multiplication.

Darshana,

See the following guide (specifically chapter 6):

CPU and Instruction Set Reference Guide
http://www.ti.com/lit/spru430

C2000 has atomic single-cycle read-modify-write operations and a single-cycle 32x32bit multiplier.

Thank you,
Brett
