Description
The Generation9-Elite series of ICs from Zoran builds upon the pro-
duction proven, class leading technology and integration of the
Generation9 family of products by bringing a new level of perform-
ance to Digital TV products. The Elite family adds dual CPUs, higher
memory bandwidth and increased application flexibility and perform-
ance to the high level of integration and outstanding quality of the
previous generation of Integrated DTV System ICs. The Generation
9-Elite IC architecture includes a multi-stream universal decoder
which can decode and playback two fully independent A/V streams
using separate time bases.

Dual CPU Performance
The dual CPU architecture of the
Elite
family allows for significantly
enhanced application software performance. This is accomplished by
using one CPU, to perform all of the tightly coupled real-time tasks in
the system. All of the low-level drivers and the real-time operating
system run on the other identical CPU. This allows nearly all of the
available CPU bandwidth of the second CPU, the Application CPU; to
be available for user defined application processing.
Elite
Software Architecture
The
Elite
software architecture developed for use in the
Elite
prod-
ucts allow for software written for Zoran's Generation9 products to
seamlessly migrate to the
Elite
products. This "virtual device" soft-
ware abstraction layer provides full Zoran API support to software
running on the Application CPU.
Elite
API support is fully backwards
compatible with the Generation9 product line allowing software writ-
ten for the Generation9 ICs to run unchanged on the
Elite
system.
Drop-In Upgrade
The
Elite
series of ICs are designed to be a drop-in upgrade to the
existing Generation9 IC. The Elites are signal and API compatible
with their respective Generation9 counterparts.
