C2000™ C28x Optimization Guide

This guide describes a systematic approach to improving the performance of applications executing on the TMS320C28x CPU in C2000™ MCUs. The guide assumes the reader is familiar with application development on C2000 MCUs. For training material on developing applications and support information, refer to C2000 real-time control MCUs - Support & training. For an overview of the key software packages associated with C2000 software development, refer to the C2000 Software Guide.
