Preface

About This Guide

The DVEVM (Digital Video Evaluation Module) is an evaluation platform

that showcases the DaVinci architecture and lets users evaluate the

power and performance of DaVinci as a Multimedia engine.

This guide gives you overview information about the board and the

software provided with the board. It is intended to be used as an

introductory document for the DVEVM. Other documents provide more

in-depth information. See the DVEVM documentation section of the

release notes for a complete list of documents that have been included

with the product.

Notational Conventions

This document uses the following conventions:

❏Program listings, program examples, and interactive displays are
