software environment. The
DMN-8600 supports MPEG-1, MPEG-2, and DV-25 encoding, decoding, transrating
and transcoding. The DMN-8600 also supports DVD playback, recording, and simul-
taneous encoding and playback of DVD streams to optical disc, enabling digital video
recording (DVR)/timeshifting applications to be developed on DVD-RAM, DVD-RW,
DVD+RW, and other recording drives. The DMN-8600 represents a quantum leap in
performance, allowing multiple A/V streams to execute simultaneously.
With its embedded, dual 32-bit RISC-based host processors with dedicated
DSP units, the DMN-8600 delivers up to 600 MIPS of processing power. This allows
the DMN-8600 to simultaneously handle multiple A/V processing functions while
managing all system control tasks, eliminating the need for an external host CPU. The
DMN-8600 also integrates a dedicated video processor and motion estimation engine
that enables advanced image processing tasks. LSI Logic鈥檚 proprietary TrueScan Pro

input video filtering algorithms leverage these
processing elements to deliver the highest quality images available in the market.
The DMN-8600 also performs all audio processing tasks, supporting industry stan-
dard audio encoding and decoding formats, as well as audio post-processing tasks
such as 3D audio effects and bass management functions.
The DMN-8600 is compatible with LSI Logic鈥檚 C-Ware architecture,which
provides hardware abstraction and an object-oriented programming environment that
is reusable across LSI Logic DoMiNo- and ZiVA鈩?based consumer digital video prod-
ucts. C-Ware is implemented in standard ANSI C/C++, provides certified software
library components and standardized API. C-Ware is compatible with WindRiver
