Operand forwarding
open-in-new
<p>Operand forwarding (or data forwarding) is an optimization in <a href="/facts/Pipeline_(computing)/xmHjrPMP">pipelined</a> <a href="/facts/CPU/Jxp1bqMV">CPUs</a> to limit performance deficits which occur due to <a href="/facts/Pipeline_stall/e3Ee0yJg">pipeline stalls</a>. A <a href="/facts/Data_hazard/hXItYfk1">data hazard</a> can lead to a <a href="/facts/Pipeline_stall/e3Ee0yJg">pipeline stall</a> when the current operation has to wait for the results of an earlier operation which has not yet finished. </p>
