Abstract

With the development of processors, the construction of a software ecosystem for RISC-V becomes a key factor in securing its position in the processor market. Binary translation technology is one of the crucial technologies for addressing compatibility issues with processor binary code and obtaining time cost for constructing a processor ecosystem. However, binary translators are unable to achieve efficient execution of binary code with low power and area overhead, making them unsuitable for widespread application in the embedded domain. To address the challenge of balancing the execution efficiency and power and area overheads of binary translators, this paper employed hardware logic acceleration to process ARMv7-M conditional execution instructions, updated flag instructions and barrel shift instructions. Then it used static binary translators to split ARMv7-M programs into IT Blocks, recalculate addresses, and map instructions to generate RISC-V binary code, supporting all types of ARMv7-M instructions. Based on the open-source CV32E40P kernel, it designed a processor core supporting ARMv7-M, and results show that the average performance of the processor core running ARMv7-M programs can reach 137% of directly running RISC-V programs. Compared with pure software binary translation to support ARMv7-M, the performance of the processor core running ARMv7-M programs improves by 5.59 times.
