Preface

About This Guide

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

that showcases the DM644x architecture and lets users evaluate the

power and performance of the DM644x as a Multimedia engine. The

intended audience is the user who is developing Linux-based software on

the DM644x ARM core.

The DVEVM does not expose the DSP core for software development,

but rather treats it as a "black box" for running off-the-shelf codecs. The

DVSDK upgrade allows you to add the ability to develop applications for

the DSP side. In addition, the DVSDK adds a full Linux license.

This guide gives you overview information about the board and the

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

"getting to know you" document for the DVEVM. Other documents

provide more in-depth information. See the DVEVM documentation index

for a complete list of documents that have been included with the product.

1.1 Welcome!

Your new DVEVM (Digital Video Evaluation

Module) will allow you to evaluate TI’s new

DaVinciTM Technology and the DM644x

architecture.

This technology brings together system-solution

components tailored for efficient and compelling

digital video and audio.

The intended audience is a user developing Linux-based software on the

DM644x ARM core. The DVEVM does not expose the DSP core for

software development, but rather treats it as a "black box" for running off-

the-shelf codecs. Separate upgrade kits from Texas Instruments will

provide tools and software for DSP development.
