The locality of the reference concept will fail where there are many unconditional jumps.

Concept

The locality of Reference: 

  • It is the phenomenon in which a computer program tends to access the same set of memory locations for a particular time period. There are two basic types of reference locality – temporal and spatial locality.
  • Temporal locality: If at one point a particular memory location is referenced, then it is likely that the same location will be referenced again in the near future.
  • Spatial locality: If a particular storage location is referenced at a particular time, then it is likely that nearby memory locations will be referenced in the near future.
  • In unconditional Jump, the computer program won't be able to access the same set of memory locations for a particular time period.

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?
