Data processing method and related device

The invention discloses a data processing method and a related device, which are used for a data transmission scene. The method comprises the steps that a controller reads a data transmission request descriptor generated by a processor, the data transmission request descriptor is generated based on a data transmission request, and the data transmission request is used for requesting transmission of target data; and the controller reads the target data from a first memory based on the data transmission request descriptor, the first memory stores the target data, and the first memory is a memory corresponding to the controller. And the controller writes the target data into the second memory based on the data transmission request descriptor. According to the application, the controller connected with the memory initiates data transmission, so that the transmission path of the data can be shortened, and the transmission efficiency of the data can be improved. 本申请公开了一种数据处理方法以及相关装置，用于数据传输场景。该方法包括：控制器读取处理器生成的数据传输请求
