The invention discloses an image data processing method and system based on RISC-V. The method comprises the following steps: generating an RISC-V processor core; defining addresses of a reqreg request configuration register and a comreg state register in the DMA control module; when it is read that a data writing request exists in the reqreg request configuration register, the DMA writing module writes image data to be processed into a memory; when a transmission ending instruction is read in the comreg state register, ending writing of the to-be-processed image data; and reading the image data to be processed from the memory and processing the image data to be processed. According to the method provided by the invention, image data processing is completed based on the RISC-V, and the data transmission and processing efficiency is relatively high. 本发明公开了一种基于RISC-V的图像数据处理方法及系统，其中的方法包括如下步骤：生成RISC-V处理器核；定义DMA控制模块中的reqreg请求配置寄存器以及comreg状态寄存器的地址；当读取到reqreg请求配置寄存器内具有写数据请求时，DMA写模块将待处理图像数据写入内存；当读取到comreg状态寄存器内具有传输结束
