Benefits Overview

additional processing tasks. The ZR38601 provides an extra 20

MIPS as well as an additional 1K words of on-chip RAM. The extra

MIPS are used to produce two-channel virtual 3-D surround using

algorithms whose program and data are conveniently stored in the

on-board EPROM.

The Virtual Surround Decoder (VSD) (ZR7386001) is a stand-alone

reference design board which integrates the Zoran^®ZR38600 or

ZR38601 digital audio signal processor with external components to

decode a Dolby Digital bit-stream into any one of six popular 3-D vir-

tual surround sound fields, for reproduction using a conventional

two-channel stereo amplifier and speakers. Three headphone algo-

rithms are also available which allow private listening with speaker-

like per-formance. The popular algorithms shown below may be

selected by the on-board hex switch.

Other ZR38600/1 post-decoding applications such as bass redirec-

tion, bass and treble equalization, or the creation of music modes

such as Stadium, Jazz Club, Concert, and Natural are possible. See

below for a list of the virtual surround algorithm suppliers. Zoran will

assist qualified customers with third-party licensing issues. This

proven reference design will significantly shorten the critical time-to-

market for OEM customers.

The ZR38600 is a 40 MIPS programmable digital audio signal

processor that performs Dolby Digital decoding from program

instructions located on-chip, and provides an extra 10 MIPS for
