MATRIX MULTIPLICATION WITH REDUCED BANDWIDTH REQUIREMENTS

PROBLEM TO BE SOLVED: To improve system performance by reducing a bandwidth needed to read inputs to a matrix multiplication operation. SOLUTION: Rather than reading a row of a first input matrix and a column of a second input matrix to produce a column of a product matrix, a column of the first input matrix and a single element of the second input matrix are read to produce a column of partial inner products of the product matrix. Therefore, the number of input matrix elements read to produce each product matrix element is reduced from 2N to N+1, where N is the number of elements in a column of the product matrix.
