Bubbling the pipeline, also termed a pipeline break or pipeline stall, is a method to preclude data, structural, and branch hazards. As instructions are fetched, control logic determines whether a hazard could/will occur. If this is true, then the control logic inserts no operations (NOPs) into the pipeline. Thus, before the next instruction (which would cause the hazard) executes, the prior one will have had sufficient time to finish and prevent the hazard. If the number of NOPs equals the n… WebApr 30, 2015 · Hazard Type - Computer Architecture. Ask Question Asked 7 years, 11 months ago. Modified 7 years, 11 months ago. Viewed 174 times ...
