Document Type and Number:
WIPO Patent Application WO/2023/240841
Kind Code:
A1
Abstract:
A chip-based image affine transformation method and a chip. The method comprises: triggering the current input cache of a plurality of input caches and an intermediate cache to read, from an off-chip memory, current partial image data of an input image and parameter data required for calculation, and respectively writing said data into the current input cache and the intermediate cache; when reading the current partial data of the input image, actuating a calculation unit to perform, via the parameter data, affine transformation and interpolation calculation on historical partial image data of the input image acquired by a historical input cache of the plurality of input caches, so as to obtain a historical partial processing result of a target output image; and writing the historical partial processing result into an output cache, and performing affine transformation and interpolation calculation on the current partial data at the same time, so as to obtain a complete processing result of the target output image.
