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.
