I need help with this. thank you

2. Determine the effective or average CPI for each of the following. Assume that the program in all cases is very large and forwarding is done. Show your work A program consists of 70% ALU instructions and 30% store instructions. Forwarding is done A program consists of 50% ALU instructions, 20% stores and 30% loads where 50% of the read result is used in the next instruction. A program consists of 40% ALU instructions, 20% stores and 20% loads and 20% jumps. None of the read result is used in the next instruction. A program consists 30% ALU instructions, 20% sw, 30% lw where 20% of the memory reads are used in the next instructions, 10% branches and 10% jumps. Branches are taken 40% of the time. There are no data dependencies with the branches causing delays. Forwarding is done. a. b. C. d
