Signal Processing on MPC5674

[dpastl]

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.
