At present, the new instruction set architecture RISC-V has attracted the attention of many chip researchers. Research based on RSIC-V processor has also developed rapidly. However, many RSIC-V-based processor designs focus on short-stage pipelines such as two-stage pipelines or three-stage pipelines, and there are few classic five-stage pipeline designs. Based on this, a five-stage pipeline processor is designed using system verilog. In order to avoid the influence of the branch jump instruction on the execution efficiency of the processor, a prediction circuit based on the dynamic branch pre-method is added. And the data related controller is added to solve the data-related problem. Finally, Modelsim software is used to build a verification environment, and the basic instruction types of RISC-V such as logic operation instructions, arithmetic operation instructions and shift operation instructions are simulated and verified.
