摘　　要：由于现有的处理器架构及IP核存在授权费用高、兼容性差等问题,近两年出现的新型RISC-V架构有着开源、免费等优势,文中基于RISC-V指令集的PicoRV32开源处理器,搭建一个精简SOC硬件平台。通过运行呼吸灯测试程序,验证了该平台的正确性。在Xilinx XCVU440的FPGA开发板下资源显示最高频率为381.2 MHz,LUTs为1137。可见PicoRV32开源微处理器具有逻辑门数少、跑频高的优点,可被用作FPGA设计和ASIC设计的辅助处理器,具有较高的研究价值和应用前景,并且所设计的平台可适用于其他处理器的SOC搭建及FPGA综合验证。Because the now available processor architecture and IP kernel has high licensing fee,poor compatibility and many other historical burdens,the new RISC-V architecture emerging in the last two years has the advantages such as open source and charge free.Therefore,a streamlined SOC hardware platform has been built on the basis of PicoRV32 open source processor with RISC-V instruction set.The correctness of the platform was verified by running the breathing light test program.Resources on the FPGA development board of Xilinx XCVU440 show:the highest frequency is 381.2 MHz and the LUTs are1137.It can be seen that the PicoRV32 open source microprocessor has the advantages of fewer logic gates and higher running frequency,which can be used as an auxiliary processor for FPGA design and ASIC design,and has high research value and application prospect.The designed platform is applied to SOC setup of other processors and FPGA comprehensive verification.
