A configurable multiplier circuit for multiplying both real and complex numbers is included in a PLD. In one embodiment, the circuit includes two adder trees. Multiplexers are used such that a conventional multiplier component is not required. The circuit is programmable to operate in one of two modes. In a first mode, the circuit multiplies the four parts of two complex numbers and outputs two values, the real portion of the product and the imaginary portion of the product. In a second mode, each of two portions of the circuit multiplies two pairs of real numbers and outputs the products.
