Design of the Instrucion Issue Algorithm for RISC Superscalar MicroProcessor

This paper proposes a dynamic instruction schedule algorithm which is based on the way of distributed control, the algorithm can effectively improve the instruction issue efficiency,decrease the complexity of instruction dispatch unit and improve the frequency of the system.The algorithm proposed by this paper is implemented in the“Longtium R3”“triple-issue”microprocessor which is designed by NWPU AMEC,and achieved the expectation.
