a. A runnable thread transitions to the blocked state when it attempts to perform a task that cannot be completed immediately and it must temporarily wait until that task completes.
b. When a thread issues an input/output request, the operating system blocks the thread from executing until that I/O request completes—at that point, the blocked thread transitions to the runnable state, so it can resume execution.

Given the branch sequence TTTTNTTNNTTTTTNNNNNNNNNTNTTTTTTTTTTTT and assuming that the 3?bit saturating predictor starts in its saturated T state, what will the predicted sequence be?
The following code is executed by an ARM processor:
MOV r0,#4
B1 MOV r2,#5
SUB r2,r2,r0
B2 SUBS r2,r2,#1
BNE B2 ;Branch 1
SUBS r0,r0,#1
BNE B1 ;Branch 2
Assume that a 1?bit branch predictor is used for both branch 1 and branch 2 and that both predictors are initially
set to N. Complete the following table by running through this code.
Repeat the same exercise with the same initial conditions but assume a 2?bit saturating counter branch predictor.
