Signal Processing on MPC5674

dpastl — Mon, 01 Feb 2016 21:17:18 GMT

Hi There,

I'm investigating adding signal processing to our product to attempt to reduce time spent on calculations. I've been reading around on the SPE2 module for the MPC5674F but I can't figure out where to start. Are there any libraries available, or application notes, on how to start using the SPE2 module with C? What I'm really curious is, do I need to add a special library or if not, what header do I include?

Thanks!

David

Following two libraries could be useful for you. These package contain a software and descriptive documents.

MPC55xx SPE DSP Library 1:

MPC55xx SPE DSP Library 2:

Also pay attention to following appnote

Will the MPC55xx libraries work for a 56xx processor?

Yes, it should work as SPE units is backward compatible.
