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.
