If yes, thats right because the other question asks to do so (add NOPs to eliminate any data dependency hazards) and the solution manual gives says the same (two NOPs after LW). But thats other question, not this question. \$\endgroup\$ WebThe following are solutions that have been proposed for mitigating aspects of control hazards: Pipeline stall cycles. Freeze the pipeline until the branch outcome and target are known, then proceed with fetch. Thus, every branch instruction incurs a penalty equal to the number of stall cycles. This solution is unsatisfactory if the instruction ...
