WebWe must flush one instruction (in its IF stage) if the previous instruction is BEQ and its two source registers are equal. We can flush an instruction from the IF stage by replacing it in the IF/ID pipeline register with a harmless nop instruction. —MIPS uses sll … Web—The clock cycle time or clock period is just the length of a cycle. —The clock rate, or frequency, is the reciprocal of the cycle time. Generally, a higher frequency is better. Some examples illustrate some typical frequencies. —A 500MHz processor has a cycle time of 2ns. —A 2GHz (2000MHz) CPU has a cycle time of just 0.5ns (500ps).
