TriMedia TM-1000
General description
The TriMediaTM TM-1000 is a general-purpose microprocessor for real-time processing of audio, video, graphics, and communications datastreams. In a single chip, TM-1000 combines an ultra-high performance, low cost CPU with a full complement of I/O and coprocessing peripheral units.
In consumer electronics appliances and personal computing prod-ucts, the TM-1000 media processor performs multimedia functions with the advantages of special-purpose, embedded DSP solutions - low cost and single-chip packaging - and the programmability of general-purpose CPUs. It improves time-to-market through high-level C/C++ language programmability and delivers throughput of up to four billion operations per second.

Features
- Processes audio, video, graphics, and communications datastreams on a single chip
- Powerful, fine-grain parallel, 100 MHz VLIW CPU with separate instruction and data caches
- Independent, DMA-driven multimedia I/O units to format data and multimedia coprocessors to offload the TriMedia CPU of specific multimedia algorithms
- High-performance bus and memory system to manage communication between TriMedia processing units
- Instruction set includes RISC, multimedia, SIMD-type DSP, and IEEE-compliant floating point operations
- Robust software development tools and libraries that enable multimedia application development entirely in C/C++ programming languages
- Configurable for standalone and plug-in card applica-tions in consumer electronics and PC products
Applications
TM-1000 is an ideal building block for any multimedia application that requires processing of video, audio, graphics, and communica-tions datastreams. It is well suited for applications ranging from single-purpose systems such as videophones, to reprogrammable, multipurpose devices such as set-top boxes or web browsers.
TM-1000 easily implements popular multimedia standards such as MPEG-1 and MPEG-2, but its orientation around a powerful, pro-grammable general-purpose CPU makes it capable of a variety of multimedia algorithms, whether open or proprietary.
