Example of structural hazards in pipelining

Structural hazard is one of the three hazards in the pipeline. A structural hazard is caused due to resource conflict in the pipeline stage. When two different instructions access the same resource in the same stage, this situation is termed a structural hazard. These structural hazards cause stalls in the pipeline. To … See more A cycle in the pipeline without new input initiation is called an extra cycle, also called a stall or hazard. When a stall is present in the pipeline, then CPI (Cycle per Instruction) ≠ 1. There are three types of hazards possible … See more The structural hazards are minimized using a hardware technique is used called renaming. The renaming mechanism states that it splits the memory into two independent sub-modules to store instruction and data … See more Let us understand the structural hazard through an example.

WebThere are different ways of handling branch hazards. The pipeline can be stalled, but that is not an effective way to handle branches. We discussed the predict taken, predict not taken and delayed branching techniques to handle branch hazards. All these are static … WebControl Hazards. Instructions that disrupt the sequential flow of control present problems for pipelines. The effects of these instructions can't be exactly determined until late in the pipeline, so instruction fetch can't continue unless we do something special. The following types of instructions can introduce control hazards:
