Question: Compute the overall total CPI for a pipelined processor that uses a branch predictor assuming the following: - Branch outcomes are determined in the EX
Compute the overall total CPI for a pipelined processor that uses a branch predictor assuming the following:
- Branch outcomes are determined in the EX phase.
- Branch prediction is accurate 70% of the time.
- Branches are 10% of program instructions.
- Due to data hazards, non-branch instructions have an average CPI of 1.2.
Please explain how you got your answer. I get stuck after multiplying accuracy with occurence (0.7)(0.1) + 1.2? not sure where to go after that.
