%X 具有开源、简单和灵活等特点，RISC-V架构受到业界广泛关注。近年来，市场上相继出现了多款RISC-V架构微处理器，32位RISC-V架构MCU正逐步进入Cortex-M MCU应用领域。本文针对将应用程序从RV32移植到Cortex-M的需求，分析RV32与Cortex-M结构、编程模型和过程调用规范等方面的不同之处，提出程序移植过程中遇到的问题，提出方法和建议，并进行相关性能分析和比较。<br>As a simplicityand flexibilityopen source microprocessor architecture, RISC-V has received widespread attention in the industry. In recent years, a lot of RISC-V microprocessors have been emerging in the market. The MCUs with the core of RV32 core are gradually entering into the ap-plication fields of Cortex-M MCUs. This article introduces the differences between RV32 and Cor-tex-M in terms of structure, programmer’s model, and procedure call convention, discusses the problems during the program porting processfromCortex-MtoRV32, proposes some suggestions, and conducts relevant performance comparison.
