Abstract :
The first single-chip 64-b vector-pipelined processor (VPP) ULSI is described. It executes vector operations indispensable to high-speed scientific computation. The VPP ULSI attains a 200-MFLOPS peak performance at a 100-MHz clock frequency. This extremely high performance is made possible by the integration on the VPP of a 64-b five-stage pipelined adder/shifter, a 64-b five-stage pipelined multiplier/divider/logic operation unit, and a 40-kb register file. Various new high-speed circuit techniques have been also developed for 100-MHz operations. The chip, which was fabricated with a 0.8-μm BiCMOS and triple-layer metallization process technology, has a 17.2-mm×17.3-mm area and contains about 693 K transistors. It consumes 13.2 W at a 100-MHz clock frequency with a single 5-V power supply
