Introduction
The DSPAUDIOEVM Evaluation Board is used to demonstrate the abilities of the DSP5636x and DSP56367x families of 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.

DSPAUDIOEVM Architecture
The DSPAUDIOEVM 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
Several different daughterboards are available to support both 5636x and 5637x Digital Signal Processor families. Each daughterboard
connects to the motherboard using two 96-pin connectors and, depending on the DSP, also contains external SRAM, FLASH or EEPROM.
(For more information on specific daughterboards see their specific sections of this manual.)
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)
The motherboard uses an included external universal power supply (100-220VAC, 50-60 Hz). The power supply uses an IEC three pin power
connector for the AC supply. The user must supply the AC cable required to connect power to the region specific AC power connection.
1.3
Debugger Interfaces
1.3.1
Suite56 OnCE
™
Debugger
The motherboard also supports multiple debugger interfaces. The Motorola high speed parallel port OnCE command converter tool is
embedded in the EVM (no special cables are required). An IEEE 1284 Parallel port cable is included in the EVM kit for convenience.
This OnCE interface can be used with the Motorola Suite56 tool set software and documentation available at
http://www.metroworks.com/MW/Develop/Embedded/suite56.htm
1.3.2
Symphony Debugger Interface
In addition to OnCE debugging, the motherboard includes a real time Symphony Debugger Interface (SDI). This debugger uses either a
RS-232 or USB interface and allows SPI or I
2
C communication to the DSP from a PC for real time debugging and configuration of the DSP.
The software and documentation to enable use of the SDI debugger are available on the web:
