Description
IBM STB03xxx Digital Set-Top Box Integrated Con-
troller family are highly integrated silicon devices
specifically developed for digital set-top box (STB)
applications using industry-leading IBM CMOS SA-
12E (0.25
μ
m) process technology.
The STB03xxx is part of the second generation of
IBM products for digital STB applications. PowerPC
processing and peripheral I/O architecture provide a
high level of performance and functionality when
used in audio and video subsystems. The resulting
STB technology is full-functioned and easy to use.
The STB03xxx minimizes host processor interven-
tion to maximize MIPS for operating system and
application tasks. Most of the features required in
the back end of typical midrange and high-end
STBs are integrated. Driver and software develop-
ment is facilitated while preserving scaleability, flexi-
bility, and extendibility.
Architecturally, the devices consist of four sub-
systems interconnected and tuned using CoreCon-
nect, the IBM multiple-bus, on-chip interconnect
structure:
1. PowerPC host processor
2. Digital audio/video
3. Memory interface
4. Peripheral
These high performance subsystems are suited to
advanced interactive STBs with demanding soft-
ware requirements including web browsers and
Java
.

obtaining approval. A Dolby Digital Audio license is required
from Dolby Laboratories.
