| Abstract: | In this paper, the concepts of superscalar and superpipeline which are adopted by modern RISC processors are discussed. Then the pipeline designs of IBM's RISC System/6000, MIPS's R4000 and CISC/RISC hybrid Intel 486 are introduced. Some implementation problmes and technique such as data dependency, branch prediction, memcory resistance and code reordering are discussed. The developing trends are pointed out at last. |
