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).
