Abstract
An apparatus for processing digital signals includes a multiplier having a first input and a second input and an output producing a product. An adder is connected to receive the product from the multiplier as a first input to produce a sum. A first register is connected to receive and store the sum and to provide a second input to the adder in response to a clock signal. A second register is connected to receive and store the output of the first register in response to an inverse of the clock signal to enable the addition of two products in a single clock cycle.
