摘　　要：RISC-V作为一种新兴的开源指令集架构,其基于RSIC-V向量指令集的算法函数尚未形成标准。在实际应用中,基于RSIC-V向量指令集的内嵌汇编函数的开发仍在发展阶段。本文以欧拉公式为算例,实现算法从ARM NEON指令集到RSIC-V向量指令集的移植,完成相关内嵌汇编函数的设计。该算法在相应的处理器平台上进行测试,结果显示基于RSIC-V向量指令集的算法效率得到显著提高。As an emerging open source instruction set architecture,RISC-V has not yet formed a standard for its algo-rithm functions based on the RSIC-V vector instruction set.In practical applications,the development of embedded assembly functions based on the RSIC-V vector instruction set is still in the developing stage.Taking Euler's formula as an example,this paper realizes the transplantation of the algorithm from the ARM NEON instruction set to the RSIC-V vector instruction set,and completes the design of the relevant embedded assembly functions.The algorithm is tested on the corresponding processor platform,and the results show that the efficiency of the algorithm based on the RSIC-V vector instruction set is significantly improved.
