Some branch instructions are much more predictable than others. if we know that 80% of all executed branch instructions are easy-to-predict loop-back branches that are always predicted correctly, what is the accuracy of the 2-bit predictor on the remaining 20% of the branch instructions?

One way to move the branch resolution one stage earlier is to not need an alu operation in conditional branches. the branch instructions would be “bez rd,label ” and “bnez rd, label”, and it would branch if the register has and does not have a zero value, respectively. change this code to use these branch instructions instead of beq. you can assume that register r8 is available for you to use as a temporary register, and that an seq (set if equal) r-type instruction can be used.

Apitfall cited in section 1.10 is expecting to improve the overall performance of a computer by improving only one aspect of the computer. consider a computer running a program that requires 250 s, with 70 s spent executing fp instructions, 85 s executed l/s instructions and 40 s spent executing branch instructions(5 min, sec 1.10)by how much is the total time reduced if the time for fp operations is reduced by 20%? (5 min, sec 1.10) by how much is the time for int operations reduced if the total time is reduced by 20%? (5 min, sec 1.10) can the total time be reduced by 20% by reducing only the time for branch instructions?

With the 2-bit predictor, what speedup would be achieved if we could convert half of the branch instructions in a way that replaced each branch instruction with two alu instructions? assume that correctly and incorrectly predicted instructions have the same chance of being replaced.
