摘要
In a floating point adder adding received two floating point data together and subtracting one such data from the other, before their exponent parts are matched in digit by a digit match unit the two data have their exponent parts compared and also their fraction parts compared, and a result of each comparison and a sign of each data are used to code a relationship in magnitude between data corresponding to a clipping coordinate and the other data fed. A clip code generated depending on the previously obtained comparison results from exponent part and fraction part compare units, rather than depending on a zero flag according to a result of an addition or a subtraction and a sign of the result of the addition or the subtraction, can rapidly be generated without the circuit increased in scale.
