24-BIT DIGITAL SIGNAL PROCESSORS
AUDIO DSP FAMILY
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
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
, the DSP56000 core family compatible
) port.
