Realization of Gmicro/200

The Gmicro/200, a microprocessor that has been developed as part of Japan's TRON (The Real-Time Operating Nucleus) project, is described. This microprogram-based processor with six-state pipeline, 730000 transistors and on-chip caches will serve in an engineering workstation or a high-speed graphics accelerator system. The authors discuss features of the instruction set; memory management; handling of exceptions, interrupts and traps; and the implementation of the Gmicro/200.<
