Abstract :
Describes a single-chip GaAs microprocessor that includes a Ling-adder-based ALU (arithmetic and logic unit), a 32-bit shifter, a 32-word register file, a 4-word write buffer, a 32-word on-chip instruction cache, support for 2 levels of off-chip instruction and data caches, and an asynchronous system interface. It uses direct-coupled FET logic and integrates 160000 transistors on a 13.9-mm*7.8-mm die. When operating from a 2-V supply, the chip typically dissipates 24 W. Portions of the chip operate at 200 MHz. Full functionality is verified at 100 MHz.<>
