Abstract

F-RISC/I, a reduced version of a fast RISC microprocessor, has been designed and fabricated using IBM´s SBFL standard cell library and Rockwell International´s 0.7 /spl mu/m HMESFET technology. F-RISC/I was designed in six months by two designers using commercial design automation tools. Simulations have shown 400 MHz operation. The chip contains 92,340 transistors on a 7/spl times/7 mm/sup 2/ die and dissipates 3.8 W. The F-RISC/I processor exemplifies the CPU architecture, circuit design, and testing developed to fully take advantage of GaAs technology for high speed computing.<>
