A multiplication system performs a series of multiplications and accumulations of plural pairs of first and second operands. The system includes first and second buses, a memory for storing the plural pairs of first and second operands, and a read buffer coupled to the memory for sequentially reading the first and second operands. An accumulator coupled to the first bus receives the first operands from the read buffer and stores the first operands. A multiplier, coupled to the first and second buses, receives the first and second operands in parallel over the first and second buses respectively from the accumulator and the read buffer respectively to provide a series of products. The system further includes an accumulator for accumulating the products to provide a final accumulated product.
