1.1 PNX17xx Series Functional Overview
audio in
The PNX17xx Series Media Processor is a complete Audio/Video/Graphics system
on a chip that contains a high-performance 32-bit VLIW processor, TriMedia
TM5250, capable of software High Definition video and audio signal processing, as
well as general purpose control processing. It is capable of running a pSOS operating
system with real-time signal processing tasks in a single programming and task
scheduling environment. An abundance of interfaces make the PNX17xx Series
suitable for networked audio/visual products. The processor is assisted by several
image and video processing accelerators that support image scaling and
compositing.
The functionality achieved within the PNX17xx Series can be divided into three major
categories: decode , processing, and display .
Decode functions take input data streams and convert those streams into memory
based structures that the PNX17xx Series may further process. Decode functions
may be simple, as in the case of storing 656 input video into memory, or substantially
more complex, as in the case of MPEG-2 or VC1.
