Echo Canceller Workbook targeting a dsPIC

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

Description

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.

• Required Products: DSP System Toolbox; Signal Processing Toolbox; Simulink; Embedded Coder; Simulink Fixed Point; Fixed-Point Toolbox; Real-Time Workshop
• MATLAB release: MATLAB 7.4 (R2007a)
• Other requirements: Microchip MPLAB IDE is required for the implementation portion.

Why I cann't run MPLAB project?

I receive the message:

Make: The target "D:\!!__KPI\M A G I S T R\!MATLAB_ecwf\ec_ert_rtw\dci.o" is out of date.
Executing: "C:\Program Files\Microchip\MPLAB C32\bin\pic32-gcc.exe" -mcpu=30F6014A -x c -c "dci.c" -o"dci.o" -g -Wall -O3
cc1.exe: error: invalid option `-mcpu=30F6014A'
Halting build on first failure as requested.
