STPC CONSUMER-S OVERVIEW
The STPC Consumer-S integrates a standard 5th
generation x86 core, a Synchronous DRAM con-
troller, a graphics subsystem, a video input port,
video pipeline, and support logic including PCI,
ISA, and IDE controllers to provide a single con-
sumer 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.
The STPC Consumer-S is packaged in a 388
Plastic Ball Grid Array (PBGA).
