Solution for data hazards in pipelining
WebStalling the pipeline •Freeze all pipeline stages before the stage where the hazard occurred. • Disable the PC update • Disable the pipeline registers •This essentially equivalent to always inserting a nop when a hazard exists • Insert nop control bits at stalled stage (decode in our example) • How is this solution still potentially “better” than relying WebDec 17, 2024 · Data Hazards • Data hazards occur when the pipeline changes the order of read/write accesses to operands so that the order differs from the order seen by …

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.
