RE: CCS/LAUNCHXL-F28377S: Cycle Count for math.h and stdlib.h

Hi devin 


Thanks for the suggestions. I already solved my sampling problems. Currently, I'm working with a Kalman filter. I have several questions.

First. How can i calculate or know how many cycles take operations from math.h or stdlib.h library i.e (+,-,/,fpow,fabsf)?
Second. Are single-plot accuracy from Debug mode CCSv7 confiable ? I display signals throuh this tool, but i think that his accuracy are poor (large delays whit respect osciloscope, a big amount of noise, etc).
Third. Can you suggest me a reference to learn about code optimize (Tips or recommendations, documents etc, )? I'm programming with c language but yet i very noob.
