Question: With the 2 - bit predictor, what speedup would be achieved if we could replace half of the individual branch instructions with a single ALU

With the 2-bit predictor, what speedup would be achieved if we could replace half of the individual branch instructions with a single ALU instruction each? (This type of optimization is sometimes possible using conditional move instructions, described on page 313.) Assume that correctly and incorrectly predicted instructions have the same chance of being replaced. Ignore all other causes of stalls or bubbles.
