Abstract :
The Distributed Instruction Set Computer Architecture (DISC) is proposed as a fine-grained multiprocessing computer architecture. DISC uses a parallel instruction set and a distributed control mechanism to explore fine-grained, parallel processing in a multiple-functional-unit system. Multiple instructions are executed in parallel and/or out of order at the highest speed of n instructions/cycle, where n is the number of functional units. Based on this architecture, a hardware system is developed. Extensive studies were conducted on a behavioral DISC system model to investigate the performance level, the effect of program sizes, and the hardware utilization. Simulation showed that a DISC system incorporating 16 functional units can run 7.7 times faster than a single-functional-unit DISC system
