Expand description
Compute dot-product of bytes in tiles with a source/destination accumulator. Multiply groups of 4 adjacent pairs of unsigned 8-bit integers in a with corresponding unsigned 8-bit integers in b, producing 4 intermediate 32-bit results. Sum these 4 results with the corresponding 32-bit integer in dst, and store the 32-bit result back to tile dst.
