A particular (fictional) CPU has the following internal units and timings: 1. IFD: Instruction fetch + decode : 160 ps 2. RR: Register read 80 ps 3. ALU: 240 ps 4. MA : memory access: 160 ps (assuming cache) 5. RW : register write : 80 ps There are 5 basic instruction types: 1. LOAD : IFD+RR+ALU+MA+RW 720 ps 2. STORE: IFD+RR+ALU+MA : 640 ps 3. ARITHMETIC: IFD+RR+ALU+RW : 560 4. BRANCH: IFD+RR+ALU : 480 ps 5. MEMOP: IFD+RR+MA+ALU+MA :...
