APPARATUSES, METHODS, AND SYSTEMS FOR A PACKED DATA CONVOLUTION INSTRUCTION WITH SHIFT CONTROL AND WIDTH CONTROL

Systems, methods, and apparatuses to support packed data convolution instructions with shift control and width control are described. In one embodiment, a hardware processor includes a decoder circuit to decode a single instruction into a decoded single instruction, the single instruction having fields that identify a first packed data source, a second packed data source, a packed data destination, a sliding window width, and a stride, and an opcode that indicates an execution circuit is to generate a first chunk of contiguous elements of the first packed data source having a width of the sliding window width, generate a second chunk of contiguous elements of the first packed data source having the width of the sliding window width and shifted by the stride, multiply each element of the first chunk by a corresponding element of a respective chunk of the second packed data source to generate a first set of products, add the first set of products together to generate a first sum, multiply each element of the second chunk by a corresponding element of a respective chunk of the second packed data source to generate a second set of products, add the second set of products together to generate a second sum, and store the first sum in a first element of the packed data destination and the second sum in a second element of the packed data destination; and the execution circuit is to execute the decoded single instruction according to the opcode.
