1) You have a program that produces the following outcomes on a single branch: T, T, T, N, T, T, T, N, T, T, T, N (where T stands for Taken and N for Not Taken). How many of these branches are predicted correctly if you are using a 1 bit branch predictor, starting out at 0 (where 1 indicates a branch will be taken)? 2) Using the set of outcomes from problem 1, how many of those branches are predicted correctly if you are using a 2 bit branch predictor, starting out at 01 (where 01 is the "weakly not taken" state)?

1) You have a program that produces the
following outcomes on a single branch: T, T, T,
N, T, T, T, N, T, T,
T, N (where T stands for Taken and N for Not
Taken). How many of these branches are
predicted correctly if
you are using a1 bit branch predictor, starting
out at 0 (where 1 indicates a branch will be
taken)?
2) Using the set of outcomes from problem 1,
how many of those branches are predicted
correctly if you are using
a 2 bit branch predictor, starting out at 01
(where 01 is the "weakly not taken" state)?
