Webb—Hazards from R-type instructions can be avoided with forwarding. —Loads can result in a “true” hazard, which must stall the pipeline. Control hazards arise when the CPU cannot determine which instruction to fetch next. —We can minimize delays by doing branch tests earlier in the pipeline. —We can also take a chance and predict the ... Webb3 okt. 2024 · There are three types of hazards possible in the pipeline, namely: Structural Hazards Data Hazards Control Hazards A structural dependency causes a structural hazard in pipelining. This dependency occurs due to resource conflict. A resource may be a memory or register or a functional unit like ALU (Arithmetic Logical Unit) in the CPU.
