I'm new to the digital motor control

I'm wondering how many cycle will cost while execute the Park or Clark Transform for the DMC library

Is there documentation like DPlib illustrate the detail of the DMC Math block?

thanks

Hi Tom,

It seems there's no such data out there but its very simple to calculate the same if you've any C2000 hardware. Use Clock Profiler in CCS.

Regards,
Gautam
