24-BIT DVD DIGITAL SIGNAL PROCESSOR
DSP56011
P ^{R E L I M I N A R Y The DSP56011 is a high-performance programmable Digital Signal Processor (DSP) developed}
for Digital Versatile Disc (DVD), High-Definition Television (HDTV), and Advanced Set-top
audio decoding. The DSP56011 is optimized with audio-specific peripherals and customized
memory configuration, and may be programmed with Motorola’s certified software for Dolby
AC-3 5.1 Channel Surround, Dolby Pro Logic, and MPEG1 Layer 2. These applications use
Motorola’s 24-bit DSP56000 architecture and are the highest quality solutions available. Flexible
peripheral modules and interface software allow simple connection to a wide variety of video/
system decoders. In addition, the DSP56011 offers switchable memory space configuration, a
large user-definable Program ROM and two independent data RAMs and ROMs, a Serial Audio
Interface (SAI), Serial Host Interface (SHI), Parallel Host Interface (HI) with Direct Memory
Access (DMA) for communicating with other processors, dedicated I/O lines, on-chip Phase
Lock Loop (PLL), On-Chip Emulation (OnCE^™) port, and on-chip Digital Audio Transmitter
(DAX). Figure 1 shows the functional blocks of the DSP56011.
