文摘This paper presents a parameterized instruction scheduling algorithm based on machine description table for TH-RISC system, having a (3-5) stages pipeline structure.It would provide considerable fiexibility for instruction scheduling, improving execution efficiency for rapidly upgrading RISC machines. Alld, using this instruction scheduler as a tool, the effect of several methods for solving instruction interlock problem has been analyzed. Finally, a high performance approach combining the hardware feasibility and software effectiveness for solving instruction interlock problem, the improvement of instruction level parallelism (ILP) and speed-up results are given.The algorithm complexity is O(n2).
