A pipelined multiplier for signed multiplication has a plurality of pipeline stages, each of which includes a row of registers, and a row of operating cells. The operating cells includes a plurality: of AND gates, NAND gates, half adders, and full adders connected to perform the signed multiplication according to the Hatamian-Cash algorithm. The pipelined multiplier is characterized by that the most significant bit of the product is directly obtained from the previous less significant bit of the product.
