MOTOROLA

SEMICONDUCTOR TECHNICAL DATA

SYMPHONY ™ AUDIO DSP FAMILY

24-BIT DIGITAL SIGNAL PROCESSORS

Motorola designed the Symphony™ family of high-performance, programmable Digital Signal

Processors (DSPs) to support a variety of digital audio applications, including Dolby ProLogic,

ATRAC, and Lucasfilm Home THX processing. Software for these applications is licensed by

Motorola for integration into products like audio/video receivers, televisions, and automotive

sound systems with such user-developed features as digital equalization and sound field

processing. The DSP56004 is an MPU-style general purpose DSP, composed of an efficient 24-bit

Digital Signal Processor core, program and data memories, various peripherals optimized for

audio, and support circuitry. As illustrated in Figure 1 , the DSP56000 core family compatible

DSP is fed by program memory, two independent data RAMs and two data ROMs, a Serial

Audio Interface (SAI), Serial Host Interface (SHI), External Memory Interface (EMI), dedicated

I/O lines, on-chip Phase Lock Loop (PLL), and On-Chip Emulation (OnCE ) port.
