Abstract

A description is given of the R3010 floating-point accelerator chip, a coprocessor that is based on advanced reduced-instruction-set-computer (RISC) architecture and VLSI design techniques and provides high-speed floating-point operation. The 75000-transistor hard-wired chip executes four instructions in parallel. Its performance is compared with that of available floating-point processors and its architecture is examined. The organization and implementation of the R3010 is discussed.
