Since R4000 is using the 8 stage pipeline, three instructions are already entered into the pipeline when the branch instruction is executed. Out of these three instructions, the first instruction will be executed for sure. My question is: What happens to the other two instruction that are in the delay slots? are they nullified? Could anyone please shed some light on this. Thanks much, -karthi ===== The expert at anything was once a beginner ________________________________________________________________________ Yahoo!
