Squarer with diagonal row merged into folded partial product array

摘要

A squarer generates an array of partial products. A method of squaring a representation of a number includes generating an array of partial products, combining the partial product on one side of a diagonal of the array with partial products on the other side of the diagonal to form a folded array of partial products, and combining each of at least one more than half of the partial products in the diagonal of the array with a corresponding one of the partial products in the folded array to produce a new folded array of partial products. In an alternative embodiment, the present invention is a circuit for squaring an n-bit representation of a number.
