PARALLEL MATRIX MULTIPLICATION TECHNIQUE OPTIMIZED FOR MEMORY FETCHES

A matrix multiplication circuit comprises a memory storage device, processing circuitry, a parallel multiply circuit, and buffer circuits. The parallel multiply circuit simultaneously performs a count of multiplies in a parallel multiplication operation. The buffer circuits include prefetch buffer circuits each having a storage array dimension corresponding to the count of multiplies in the parallel multiplication operation. The processing circuitry loads a first prefetch buffer circuit with values from the first matrix; fetches a value of the second matrix and, in parallel with the fetch, preload the second prefetch buffer circuit with another value from the first matrix; initiates a parallel multiply of the fetched value of the second matrix and the values in the first prefetch buffer circuit; and stores partial product results of the parallel multiply, including adding a current partial product result to a previously stored partial product result.
