Abstract: A fast implementation of cycle-level processor simulator is introduced，which is based on function-level processor simulator，with timing-directed method involved.This method uses an instruction pipeline to drive function module of processor simulator work，such as ALU，Co-processor，MMU，and TLB.This paper presents the design of a classic pipeline of RISC/MIPS instruction set，and how to integrate the pipeline and function module of processor simulator，to generate a cycle-level processor simulator framework.The tests of SPEC CPU 2000 prove that，this cycle-level processor simulator has high accurate and performance.
