A single-chip MPEG-2 MP@ML audio/video encoder/decoder with a programmable video interface unit

We present a single-chip, MPEG-2 main profile at main level, audio and video encoder and decoder. It combines a RISC core, a 24-bit DSP, video and audio interface units, and several dedicated processing units. A programmable video interface unit supports multiple modes of pre- and post-processing and on-screen display (OSD). The codec has been implemented using a standard-cell library in 0.18 /spl mu/m CMOS technology.
