STPC CONSUMER OVERVIEW
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.
The STPC Consumer is packaged in a 388 Plastic
Ball Grid Array (PBGA).
