The paper presents a comparative study of circuit area and performance degradation among four pipelined RISC processors using different precise interrupt methods. The precise interrupt methods studied, include inorder completion, reorder buffer, history file and future file. The VHDL is used to model five machines at the register transfer level. The Synopsys design compiler is used to synthesize these machines as a netlist of CMOS logic gates, then gate counts are obtained. Based on our model architecture and benchmark programs, it shows that the history file method can achieve the highest performance and consume less silicon area than the reorder buffer method and the future file method
