Dear Richard, Thanks for your quick reply, i also tried IQ math lib and the results are at 8 KSps i am clocking dsp at max of 60 MHz. I'll try to implement PI regulator in the motor library and keep you updated. So if this is a constraint on the device how is it possible to design a PID control or PI with high sampling rate (not sure with this device) ? Am i missing something here..... And my loop speed reduced only when i use "Static float" type operands inside the routine. Can you please explain me how "Static float or int" reduces the loop speed? I have seen the same with global and arrays (both global and local) thanks!!!
