Title:
DATA PROCESSING METHOD AND DEVICE, DMA CONTROLLER, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/127517
Kind Code:
A1
Abstract:
A data processing method and device, a DMA controller, and a computer readable storage medium. The method comprises: acquiring feature information from at least two original output feature maps, and generating, for each original output feature map, and according to the feature information of the original output feature map, DMA read configuration information and DMA write configuration information; and reading input data from each original output feature map according to the DMA read configuration information of the original output feature map, and storing the read input data in a target output feature map according to the DMA write configuration information of the original output feature map. Implementing an embodiment of the present invention realizes transfer of data in a CNN by means of a DMA controller, such that load of a CPU is reduced, thereby enabling more efficient data transfer, and accordingly accelerating a CNN operation while maintaining flexibility.
