WebThe dependencies occur for a few reasons which we will be discussing soon. The dependencies in the pipeline are called Hazards as these cause hazard to the execution. … WebDetecting MEM/WB data hazards A MEM/WB hazard may occur between an instruction in the EX stage and the instruction from two cycles ago. One new problem is if a register is updated twice in a row. add$1, $2, $3 add$1, $1, $4 sub$5, $5, $1 Register $1 is written by both of the previous instructions, but only the
WebThe possible data hazards are RAW (read after write) — j tries to read a source before i write it, so j incorrectly gets the old value. ...

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…
