  • In the case of the delayed load technique, the compiler detects the data conflict and recorder the instruction as necessary to delay the loading of the conflicting data by inserting no operation instructions (NOP).
  • Therefore the method used for resolving data dependency conflict by the compiler itself is delayed load.

More Pipelining Hazards Questions

Q1.A processor X1 operating at 2 GHz has a standard 5-stage RISC instruction pipeline having a base CPI (cycles per instruction) of one without any pipeline hazards. For a given program P that has 30% branch instructions, control hazards incur 2 cycles stall for every branch. A new version of the processor X2 operating at same clock frequency has an additional branch predictor unit (BPU) that completely eliminates stalls for correctly predicted branches. There is neither any savings nor any additional stalls for wrong predictions. There are no structural hazards and data hazards for X1 and X2. If the BPU has a prediction accuracy of 80%, the speed up (rounded off to two decimal places) obtained by X2 over X1 in executing P is ______.
Q2.Which of the following hazards occurs when the pipeline makes the wrong decision on a branch prediction and therefore brings instructions into the pipeline that must subsequently be discarded?
