Course: ((computer architecture))

1. How many clock cycles it take to process the first 11 instructions using the pipeline machine above? 2. If the LW instruction causes 2 stall cycles, and the LW is 30% of the code, and that Branch causes 3 stall cycles and it is 10% of the code. Calculate the CPI for the noneideal pipeline? Ideal pipeline CPI is equal to 1.

g. Use the table below to fill out the processing of the above code through the pipeline machine. Assume all instruction now take the same number of cycles to execute, and branch is never taken. Clock Cycles 1 2 3 4 1 5 6 7 08 09 10 | 11 12 13 14 15 16 17 18 Instruction IF ID IE MEM WB add1 add2
