[理工] [理工] datapath
multi-cycle datapath 相對於 single-cycle datapath 最主要的優點是什麼?
1.The ability to allow instructions to take shorter cycle time
2.The ability to allow instructions to take same number of clock cycles
3.The ability to allow a functional unit to be used more than once per
instruction in the same clock cycle
4.The ability to overlap executing different instructions.
請問哪個是主要的優點
還有第3個敘述不太懂他的意思
麻煩了~感謝
