Total sum calculation circuit capable of rapidly calculating a total sum of more than two input data represented by a floating point representation

Abstract From the Canadian patent

In a total sum calculation circuit for the use in calculating a total sum of first through n-th input data which are represented by a floating point representation and which are composed of first through n-th exponent parts and first through n-th fraction parts where n is, an integer greater than two an n-input data comparison, circuit simultaneously compares the first through the n-th exponent parts with one another to produce a maximum one of the first through the n-th exponent parts and a comparison result signal representative of which one of the first through the n-th exponent parts is the maximum exponent part. Supplied with the first through the n-th exponent parts and the comparison …
