description | The invention discloses a hardware acceleration system and method for fingerprint recognition, and belongs to the field of fingerprint recognition. The hardware acceleration system comprises a hardware acceleration unit, a memory and a central processing unit, a computing controller and a DMA controller are arranged in the hardware acceleration unit, the computing controller is electrically connected with the central processing unit and the memory through a system bus, and the DMA controller is electrically connected with the memory through the DMA bus. The method comprises: a hardware acceleration unit divides an image into a plurality of sub-blocks with the same size according to the size of the image, then the hardware acceleration unit reads data of the sub-blocks in a memory and calculates the directions of the sub-blocks, and then filtering processing is conducted on the data of the sub-blocks according to the directions of the sub-blocks; and reading and processing the data of the next sub-block until |
