Operand forwarding (or data forwarding) is an optimization in pipelined CPUs to limit performance deficits which occur due to pipeline stalls. [1] [2] A data hazard can lead to a pipeline stall when the current operation has to wait for the results of an earlier operation which has not yet finished. flow button test
