摘要：Methods and apparatus for predicting an underflow condition associated with afloating-point multiply-add operation are disclosed. An example apparatus obtains a first
operand value and a second operand value. The example apparatus then determines ifthe second operand value subtracted from the first operand value is greater than aminimum value and determines if the first operand value is greater than a sum valueassociated with a minimum operand value. The example apparatus then asserts an outputsignal indicative of an absence of an underflow condition associated with a floating-pointvalue based on conditions associated with determining whether the second operandvalue subtracted from the first operand value is greater than the minimum value anddetermining if the first operand value is greater than the sum value.
