DSP56362 Product Brief
Product Brief
This document contains information on a new product. Specifications and information herein are subject to change without notice.
24-BIT AUDIO DIGITAL SIGNAL PROCESSOR
The DSP56362 is a high performance DSP optimized for cost-sensative consumer audio
applications. A general purpose DSP56362 is available as well as a multimode, multichannel audio
decoder for consumer applications such as Audio/Video (A/V) receivers, surround sound decoders,
Digital Versatile Disk (DVD) players, digital TV, and other audio applications. The DSP56362
supports all of the popular multichannel audio decoding formats, including Dolby Digital Surround,
Moving Picture Experts Group Standard 2 (MPEG2), and Digital Theater Systems (DTS), in a single
device with sufficient MIPS resources for customer defined post-processing features such as bass
management, 3D virtual surround, Lucasfilm THX5.1, soundfield processing, and advanced
equalization.
The DSP56362, Figure 1,is member of the 56300 Motorola Symphony™ DSP Family. The
DSP56362 utilizes the single-instruction-per-clock-cycle DSP56300 core, while retaining code
compatibility with the DSP56000 core family. The DSP56362 contains audio-specific peripherals and
an on-board software architecture as shown in Figure 2 and is offered in a 100/120 MHz/MIPS
version at a nominal 3.3 V.
