Introduction

This document provides a description of how to upgrade the standard DSP56362EVM 
Evaluation Module to the DSPD56362 and related components. After the upgrade is complete 
the EVM system will be capable of autodectect/autoswitching of PCM, Dolby Digital

TM

DTS

TM

 and MPEG bitstreams in addition to various post decoder functions. The user interface 

of the upgraded EVM is also described.
