  • FUSED MULTIPLY ADD PIPELINE
    Publication number: 20140244704
    Abstract: A method for operating a fused-multiply-add pipeline in a floating-point unit of a processor is disclosed. A multiplication is initially performed between a first operand and a second operand in a multiplier block to obtain a set of partial product results. The partial product results are sent to a carry-save adder block. A partial product reduction is performed on the partial product results to generate a carry-save result having a sum term and a carry term. The carry-save result is then formatted to generate a carry-out bit. The carry-save result is added to a third operand to generate a final result.
