Product Brief
24-Bit DSP56002 Evaluation Module
The DSP56002EVM Evaluation Module (EVM) is a low-cost platform designed to familiarize the
user with Motorola’s DSP56002 Digital Signal Processor (DSP). The 24-bit precision of the DSP
combined with the on-board 32k words of external SRAM and stereo CD-quality audio codec
makes the EVM ideal for implementing and demonstrating many audio processing algorithms as
well as for learning the architecture and instruction set of the DSP56002 processor. The user need
only supply a 7–9 volt calculator-style power supply and an RS-232 serial cable. Figure 1 illustrates
the hardware.
The DSP56002EVM comes with Motorola’s DSP56000 cross assembler and Domain Technologies’
debug software with windowed user interface. The software runs under MS-DOS on an IBM PC-
compatible computer (-386 class or higher) and communicates with the EVM over an RS-232 serial
port.
