....which could benefit from complementary GaAs because of its speed at low power supply voltages. The state of the art in CMOS low power processors is exemplified by the IBM 401GF, which consumes just 40 mW (typical) from a 2. 5 V supply at 25 MHz; 100 MHz parts are expected before the end of 1996 [6]. CGaAs, operating with a 1 V supply, would have a dynamic power advantage of 1:6.25 over this 2.5 V CMOS process if parasitic capacitances were equivalent. II. COMPLEMENTARY GAAS CGaAs overcomes many of the problems of E D MESFET DCFL technology, in which we have designed several prototype ....

....together (e.g. Pegwit and PGP) Additionally, because most of these codes operate on real time data streams, the runtime is highly dependent on the size of the available test files. The processor core is based on the IBM 40x PowerPC cores, with an estimated size of 8 mm 2 in 0. 5um technology [24]. Cache area is calculated using the Cache Design Tools [25] We assume that the external memory bus is wide enough to satisfy a fundamental read operation with a single transaction. Thus, the penalty for a miss is simply the main memory latency. For the experiments here we use a value of 10 ....
