Claim One:
1. A convolution image processor comprising: a load and store unit configured to load and store image pixel data and stencil data such that the load and store unit provides unaligned access to the image pixel data; a shift register unit configured to load and store at least a portion of the image pixel data from the load and store unit and concurrently provide access to each image pixel value in the portion of the image pixel data; and a mapping unit comprising: a plurality of interface units each configured to: generate a plurality of shifted versions of image pixel data from the portion of the image pixel data such that a pattern of the shifted versions of image pixel data is different between each of the plurality of interface units; and provide corresponding stencil data to the shifted versions of image pixel data; and a plurality of arithmetic logic units (ALUs) configured to concurrently perform one or more operations on each image pixel value in the plurality of shifted versions of the portion of the image pixel data and a corresponding stencil value in the corresponding stencil data provided from a subset of the plurality of interface units, wherein the subset of the plurality of interface units and the one or more operations performed on each image pixel value are programmable.
