MOTOROLA DSPAUDIOEVM Evaluation Board Users Manual 1

This document contains information on a new product. Specifications and information herein are subject to change without notice.

SECTION 1 OVERVIEW

1.1 Introduction

The DSPAUDIOEVM Evaluation Board is used to demonstrate the abilities of the DSP56362, DSP56364,

DSP56366, and DSP56367 Digital Signal Processors and to provide a hardware tool allowing the

development of applications that use these devices.

The DSPAUDIOEVM is designed for the following purposes:

• To allow new users to become familiar with the features of the 56300 architecture: The tools and examples

provided with the DSPAUDIOEVM facilitate evaluation of the feature set and the benefits of the family.

• To serve as a platform for real-time software development: The tool suite enables the user to develop and

simulate routines, download the software to on-chip or on-board RAM, and then run and debug the

software using a debugger via the JTAG/OnCE port or the Serial Host Interface port. The breakpoint

features of the OnCE port enable the user to easily specify break conditions and to execute user-

developed software at full speed, until the break conditions are satisfied. The ability to examine and

modify all user-accessible registers, memory, and peripherals through the OnCE or SHI port greatly

facilitates the task of the developer.

• To serve as a platform for hardware development. The hardware platform enables the user to connect

external hardware peripherals. The on-board peripherals can be disabled, providing the user with the

ability to reassign any and all of the DSP’s peripherals. The OnCE port’s unobtrusive design means that

all of the memory on the board and on the DSP chip is available to the user.

1.2 DSPAUDIOEVM Architecture

The DSPAUDIOEVM Audio EVM system is a development tool for authoring and testing of Digital Audio

DSP software. It can also be used as a demo platform for Motorola’s digital audio DSP technologies. The

EVM system consists of a motherboard and a daughterboard (Ordered separately).

1.2.1 Daughterboard

The daughterboard connects to the motherboard by way of two 96 pin connectors and includes a 512Kx8

FLASH, three 128Kx8 SRAM (one 128Kx8 for the 56364 daughterboard) and one of the DSP options. The

daughterboard supports all of the 5636X DSPs but will be populated with the DSP associated with the part

number ordered. The daughterboard is designed to be upgraded/replaced as future DSPs become available

while reusing the existing EVM motherboard.

1.2.2 Motherboard

The motherboard has a variety of digital and analog audio I/O including:

• 4 switchable S/PDIF inputs (2 optical and 2 Coaxial)

• 4 simultaneous S/PDIF outputs(3 Coaxial and 1 Coaxial/Optical)

• 12 analog output channels(6 stereo RCA type connectors)

• 2 analog microphone inputs

• 2 analog inputs (1 stereo RCA type connectors)

• Headphone output (can mix any combination of analog signals using switch array)
