Processors with multiple functional units, such as CRAY-1, Cyber 205, and FPS 164, have been used for high-end scientific computation tasks. Much effort has been put into increasing the throughput of such systems. One critical consideration in their design is the identification and implementation of a suitable instruction issuing scheme. Existing approaches do not issue enough instructions per machine cycle to fully utilize the functional units and realize the high-performance level achievable with these powerful execution resources.
