1.1 PNX15xx Series Functional Overview
audio in
The PNX15xx Series Media Processor is a complete Audio/Video/Graphics system
on a chip that contains a high-performance 32-bit VLIW processor, TriMedia
TM3260, capable of software 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 PNX15xx Series suitable for
networked audio/visual products. The processor is assisted by several image and
video processing accelerators that support image scaling and compositing.
pictures a high level functional block diagram.
The functionality achieved within the PNX15xx 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 PNX15xx 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.
