A processor has a branch?target buffer. If a branch is in the buffer and it is correctly predicted, there is no branch penalty. The prediction rate is 85% correct. If it is incorrectly predicted, the penalty is 4 cycles. If the branch is not in the buffer, and not taken, the penalty is 2 cycles. Seventy percent of branches are taken. If the branch is not in the buffer and is taken the penalty is 3 cycles. The probability that a branch is in the buffer is 90%. What is the average branch penalty?
