Benefits Overview
The EZ5.1 is a reference design integrating the ZR38601 program-
mable digital audio processor with other low-cost components into a
multi-format decoder. This production-ready design can serve as the
core digital audio decoder in a 5.1-channel A/V receiver. It offers the
audio product designer 20 MIPS with which to create product-differ-
entiating features. The EZ5.1 can implement music modes, virtual
3-D surround sound for speakers or headphones, Karaoke process-
ing, and bass management. Customers may further expand the
scope of their product by adding their own, or third-party, software
stored in the convenient on-board EPROM, or downloaded using
simple system commands. SiliconSoftware
is a collection of
versatile applications of both Zoran
’s own and third-party developed
applications that run on the ZR38600 family of processors. Zoran is
committed to supplying the hardware and software that are capable
of decoding today’s formats as well as emerging formats such as
AAC, MLP, and DTS. The EZ5.1 reference design illustrates Zoran’s
StandardsPlus
approach to customer support, proven to lower
OEM’s costs and shorten the time-to-market.
