This paper describes the architecture, functionality and design of TM-2700a digital television and media processor chip from Philips Semiconductors. The chip not only supports all eighteen digital television picture formats [l] prescribed by the United States Advanced Television Systems Committee (ATSC) [2], from standard-definition to wide-angle high-definition video, but has also the power to handle High-Definition Television (HDTV) video and audio source decoding (highlevel MPEG-2 video, AC-3 and ProLogic audio, closed captioning, etc.) as well as the flexibility to process advanced interactive services.TM-2700 is a programmable processor with a very powerful, generalpurpose Very Long Instruction Word (VLIW) Central Processing Unit (CPU) core that implements many non-trivial multimedia algorithms, coordinates all on-chip activities, and runs a small real-time operating system. Aided by an array of peripheral devices and high-performance buses, the CPU core facilitates concurrent processing of audio, video, graphics, and communication-data. 0-7803-5650-0/99/$10.00 0 1999 IEEE
