Advance Information

24-BIT DVD DIGITAL SIGNAL PROCESSOR

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.
