Abstract:
An apparatus for calculating a reciprocal value for a binary operand, comprising:a first table tabulating a plurality of estimated reciprocal values, each estimated reciprocal value associated with a reciprocal index value, in response to receipt of a portion of the binary operand matching one of the reciprocal index values, the first table providing the estimated reciprocal value associated thereto; a second table tabulating a plurality of reciprocal error values, each reciprocal error value associated with an error index value, in response to receipt of a portion of the binary operand matching one of the error index values, the second table providing the reciprocal error value associated thereto; and a combining component coupled to the first and second tables to receive the estimated reciprocal values and the reciprocal error values, the combining component further calculating the reciprocal value for the binary operand therefrom.
