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