3. Why is a single instruction in a pipeline datapath not shorter than that in a multi-cycle datapath even though totally a pipeline mechanism performs better. Please select the correct choice. US (30 Puan) Because of quicker time of execution of large number of instructions Because pipelined CPUs generally work at a higher clock frequency than the RAM clock frequency Because it is possbile to execute multiple instructions sequentially Because increase in the number of pipeline stages increases the number of instructions executed simultaneously Because in a pipeline architecture 1 instruction abandons the pipeline in each cycle so the CPI will be of 1
