DSP56362

Product Brief

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.
