Store-after-load data dependence. Consider copying an array of n words from one address in memory to another. This can be accomplished by placing a sequence of lw and sw instructions in a loop, with each loop iteration copying one word. In the current pipelined implementation shown in the lecture slides, this leads to one bubble (stall cycle) between lw and sw. Is it possible to avoid this stalling via additional data forwarding hardware? Discuss how this can be done or explain how the bubble is unavoidable.
