Answer #1

Answer)

The stalling penalty for a pipelined Y86 ret instruction is of 3 cycles because to handle the data hazards by forwarding, to load/use the hazards when needed by one cycle. The other cycle is for canceling of the instruction which helps in detecting the mispredicted branch while the ret passes via pipelines. The third is for control combination which is meant for analyzing the combination carefully and subtling the bug.
