STPC CONSUMER OVERVIEW

PCI BUS

The STPC Consumer integrates a standard 5th

generation x86 core, a DRAM controller, a graph-

ics subsystem, a video pipeline and support logic

including PCI, ISA and IDE controllers to provide a

single Consumer orientated PC compatible sub-

system 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

color space conversion of the video input stream

and mixing with graphics data. The chip also in-

cludes a built-in digital TV encoder and anti-flicker

filters that allow stable, high-quality display on

standard PAL or NTSC television sets without ad-

ditional components.
