Abstract
A method, performed by a processor, of determining a square root using a single processor cycle per iteration is described. The method includes, in a single cycle: obtaining, from a stored lookup table, a quotient digit and a square of the quotient digit; retrieving a current solution; and determining a new solution using the current solution and the quotient digit. Circuitry configured to perform the method is described.
