Fuente: Wipo "digitalization" An apparatus comprises combined divide/square root processing circuitry to perform, in response to a divide instruction, a given radix-64 iteration of a radix-64 divide operation, and in response to a square root instruction, a given radix-64 iteration of a radix-64 square root operation; in which: the combined divide/square root processing circuitry comprises shared circuitry to generate at least one output value for the given radix-64 iteration on a same data path used for both the radix-64 divide operation and the radix-64 square root operation.
