FR-V Single-Chip Multicore Processor:FR1000

To realize the low power consumption and low-cost equipment needed to decode high definition broadcasts, Fujitsu has developed a single-chip multicore processor FR1000 that integrates four 8-way, Very Long Instruction Word (VLIW) FR-V processor cores. This new multicore processor is fabricated using a 90 nm, nine-metal-layer CMOS process and a 900-pin flip-chip package. The processor cores operate at 500 MHz, the memory interfaces at 250 MHz, and system bus at 166 MHz. The use of a single processor core enables MPEG-2 MP@ML video-stream decoding at 190 MHz. Conversely, the use of four processor cores enables the decoding of MPEG-2 MP@HL video streams by just using software. Moreover, this new processor needs only about 3 W to decode MPEG-2 MP@HL video streams. This paper introduces the hardware and software development environment of this new processor, describes the processor’s software operation environment, and cites some examples of its application.
