Data processing method and device based on buffer, storage medium and electronic device

Abstract

The invention provides a data processing method and device based on a buffer, a storage medium and an electronic device, and the method comprises the steps: firstly determining a target mobile storagespace of the buffer based on the storage space of the buffer and the parameters of a convolution kernel; then, splitting the image to be processed into a first sub-image and at least one second sub-image; then, performing convolution processing on the first sub-image, and after to-be-removed data which is subjected to convolution processing and has the same size as the target mobile storage spacein the first sub-image is removed, reading the second sub-image to a buffer, and then contining convolution processing. Visibly, in the scheme, after the bandwidth data of the first subimage is readfor the first time, only the bandwidth data of the second subimage needs to be read, and the bandwidth data of the second subimage is smaller than the data of the whole image to be processed, so thatthe scheme can reduce the reading bandwidth of the buffer and repeatedly utilize the limited storage space of the buffer, thereby improving the space utilization rate.

Description

technical field [0001] The invention relates to the technical field of data calculation, in particular to a buffer-based data processing method, device, storage medium and electronic equipment. Background technique [0002] In the FPGA, the data read from the DDR needs to be temporarily stored in the buffer buffer. Generally, the faster the processing speed of the FPGA, the larger its area, and the larger the area, the higher its cost. Therefore, considering factors such as cost, the buffer space in the FPGA is limited. [0003] At present, when performing image processing, it is necessary to read all the data of the image, so that the reading bandwidth is large. Therefore, how to provide a buffer-based data processing method that can reduce the read bandwidth and improve buffer utilization is a major technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the embodiment of the present invention provides a ...
