Question 3 (25points) A LOAD/STORE machine has the characteristics shown below.

Question 3 (25points) A LOAD/STORE machine has the characteristics shown below. Instruction Type Frequency CPI ALU 0.36 1 Loads 0.32 3 Stores 0.12 2 Branches 0.20 2 Table-1 We observe that some of the ALU operations directly use a loaded value that is not used again. We hope to improve things by adding new types of instruction that have one source operand in memory, and thus reduce the dependency on the Loads and ALU operation by 25%, while the number of the other instructions remain unaffected. The CPI of the new instructions is 2. 1. (8 points) Show the characteristics of the new system in a format similar to the Table-1. 2. (17 points) Overall, what will be the CPU performance increase or decrease
