SYMPHONYTM AUDIO DSP FAMILY
24-BIT DIGITAL SIGNAL PROCESSORS
Motorola designed the SymphonyTM 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 DSP56007 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 (OnCETM) port. The
DSP56007 has significantly more on-chip memory than the DSP56004.
