Architecture, Design, and Verification of an 18 Million Transistor Digital Television and Media Processor Chip
This paper describes the architecture, functionality, and design of NX-2700 — a digital television (DTV) and media-processor chip from Philips Semiconductors. NX-2700 is the second generation of an architectural family of programmable multimedia processors that supports all eighteen United States Advanced Television Systems Committee (ATSC)  formats and is targeted at the high-end DTV market. NX-2700 is a programmable processor with a very powerful, generalpurpose Very LongInstruction Word (VLIW) Central ProcessingUnit (CPU) core that implements many non-trivial multimedia algorithms, coordinates all on-chip activities, and runs a small real-time operating system. The CPU core, aided by an array of autonomous multimedia coprocessors and input-output units with Direct Memory Access (DMA) capability, facilitates concurrent processingof audio, video, graphics, and communication-data.
