Abstract
A bridge fused multiply-adder is disclosed. The fused multiply-adder is for the single instruction execution of (A×B)+C. The bridge fused multiply-add unit adds this functionality to existing floating-point co-processor units by including a fused multiply-add hardware 'bridge' between an existing floating-point adder and a floating-point multiplier unit. This fused multiply-add functionality is added to existing two-operand architecture designs without degrading the performance or parallel pipe execution of floating-point adder and floating-point multiplier instructions.
