STPC CLIENT OVERVIEW

The STPC Client integrates a standard 5th

generation x86 core, a DRAM controller, a

graphics subsystem, a video pipeline, and

support logic including PCI, ISA, and IDE

controllers

orientated PC compatible subsystem on a single

device.

The device is based on a tightly coupled Unified

Memory Architecture (UMA), sharing the same

memory array between the CPU main memory

and the graphics and video frame buffers.

Extra facilities are implemented to handle video

streams. Features include smooth scaling and

colour space conversion of the video input stream

and mixing of the video stream with non-video

data from the frame buffer. The chip also includes

anti-flicker filters to provide a stable, high-quality

Digital TV output.

The STPC Client is packaged in a 388 Plastic Ball

Grid Array (PBGA).
