Echo Canceller Workbook targeting a dsPIC

This set of models and word documents show an echo canceller development workflow.

You are now following this Submission

The purpose of this workflow is to bring new users up to speed as quickly as possible on Simulink and Model-Based Design. It does this in the context of an echo canceller example targeted for a Microchip DSP. We concentrate on good modeling practices, C code generation, MATLAB integration in Simulink, how to target a Microchip dsPIC, and code verification using Simulink test benches. It’s important to point out that the steps required to target a dsPIC are similar to those for targeting any DSP. This workflow does all of this using an integrated set of Word files, M-files, and Simulink models. We hope you find it useful.
This echo canceller workflow is broken into a series of 10 chapters.
