WebApr 12, 2024 · 2. The names of the pipeline stages are somewhat less than standard. More common is to use IF (instruction fetch from Instruction Memory IM), ID (instruction decode and register read), EX (execute/ALU), MEM (Data Memory read or write), and WB (write back register result). Whether it is 2 vs. 3 clock cycles depends on your internal architecture.

WebIn this session, we talk about solution of Data hazards which occur in 5-stage MIPS pipeline. WebThe beq instruction presents a control hazard: the pipelined processor does not know what instruction to fetch next, because the branch decision has not been made by the time the next instruction is fetched. …. Once the branch decision is available, the processor can throw out the instructions if the prediction was wrong.
