Computer Architecture

Problem 2 (30 points) One machine uses a 2 GHz clock and executes a program with 4 classes of instructions, A, B, C, D Their respective cycles/instruction are CPlA-3, CPls-2, CPlc 4, and CPlo-2. Another machine has a faster clock of 3.2 GHz, and a different architecture, such that the same classes of instructions have CPlA-2, CPlB 2, CPlc-3, and CPlo 2. Both machines execute a program where the frequency of the four classes of instructions is 30% for Class A, 20% for Class B, 10% for Class C and 40% are instructions of Class D 1) How er naly struach of the machines esecute in 10 seconds (assume no overhead)? 2) If a program has 109 instructions, which machines finishes first? 3) Which machine is more performant? 4) Compare the MIPS of the two machines
