Abstract
A method for computing an intermediate result in squaring a number using a multiplier circuit of predetermined operand size, the method including the steps of representing a number to be squared as a vector of binary digits; grouping the vector into successive segments each having a length of the predetermined operand size; multiplying a first segment value by a second segment value to generate a first product value; the second at least one of the segment values to derive a second product value; halving the second product value to generate a halved second product value; accumulating the first product value with the halved second product value to generate an accumulated value; and doubling the accumulated value to generate the intermediate result.
