From above question, if a branch instruction is a conditional branch instruction, the branch need not be taken; if the branch is not taken, the following instructions can be overlapped. When 80% of all branch instructions are conditional branch instructions, and 50% of the conditional branch instructions are such that the branch is taken, what is the average instruction execution time?
