About This Guide

This document is intended to guide the user through all aspects of installation,
demonstration, simulation, verification, and general usage of the Motion Estimation
Engine core. It should be read in conjunction with the Xilinx Motion Estimation Engine
Product Specification (DS648).

Guide Contents

This manual contains the following chapters:

• “Introduction,” provides information about the core, recommended design

experience, additional core resources, technical support, and core and document
feedback.

• “Installing the H.264 Motion Estimation Engine Core,” provides instructions for

installing the core.

• “Designing with the H.264 Motion Estimation Engine Core,” describes how to include

the core into the designer’s system, along with a list of the files provided.

• “Simulating the H. 264 Motion Estimation Engine Core,” describes a test bench

architecture that was created in the ModelSim® environment for simulation of the
core.

• “Verifying the System,”describes the verification environment delivered with the

core.

• Appendix , “Supporting Information,”provides the input sequences, directory tree

structure, regression test summary, and references.
