Chapter 4, Problem 4.16.6E

Explanation of Solution

Given:

Branch outcome is T, NT, T, T, and NT.

T: Taken

NT: Not Taken

Design of the predictor:

The below is the design of the N-bit shift register that achieves a better result when the pattern gets repeated forever:

Explanation:

  • The predictor is designed using the N-bit shift register such that it would achieve a perfect accuracy when the pattern is also opposite.
  • N indicates the target patterns outcome that is number of branches.
  • The pattern for the shift register is being initialized with the pattern that is 0 for NT and 1 for T...
