摘　　要：服务器管理控制器是云计算装备关键部件之一,目前主要基于ARM架构开发,ARM较高的授权费推高了控制器设计成本,不利于SoC相关产品的迭代和升级.RISC-V是近年提出的一种开源的处理器架构,与ARM同属精简指令集,具有模块化、可扩展等诸多特点.本文采用RISC-V开源处理器BOOM核心,设计实现了一种基于RISC-V处理器的服务器管理控制器FPGA原型系统.该系统基于Xilinx的Virtex Ultra Scale 440 FPGA进行了原型构建,完成了实际应用场景下的功能测试和CoreMark测试,结果显示处理器性能提升了26%,优于同级别的ARM核心,系统功能符合设计预期.此外,该原型系统基于OpenBMC实现了IPMI等专用管理控制协议,基本功能验证通过,证明了通过RISC-V替换ARM优化SoC架构的可行性.The server management controller,as a key component of cloud computing equipment,is mainly based on ARM architecture at present.However,ARM’s high licensing fees push up its design cost,which is not conducive to the iteration and upgrade of SoC-related products.RISC-V,which is an open-source processor architecture proposed recently,belongs to the reduced instruction set as ARM.It has many features such as modularity and scalability.In this study,we combine the BOOM core of a RISC-V open-source processor to design and implement an FPGA prototype system of a server management controller based on a RISC-V processor.In the system,we build a prototype based on Xilinx’s Virtex Ultra Scale 440 FPGA and complete the functional and CoreMark tests in the actual application scenarios.The results show that the processor performance is improved by 26%,which is superior to that of products of the same level that use ARM as the core,and the system’s functions are in line with design expectations.In addition,based on OpenBMC,this system implements special management control protocols such as IPMI,and its basic functions are verified,which proves the feasibility of optimizing SoC architecture by replacing ARM with RISC-V.
