Conditional Branch Instructions (Common): Include the following instruction types:
The pipeline has three stages: IF, ID, and EX. Condition verification is performed in the ID stage.
Conditionally branched instructions are not delay branched.
1. When condition is satisfied
2. When condition is not satisfied
BF label
BT label
The branch destination address is calculated in the EX stage. The two instructions after the
conditional branch instruction (instruction A) are fetched but discarded. The branch destination
instruction begins its fetch from the slot following the slot which has the EX stage of
instruction A (figure 7.78).
If it is determined that conditions are not satisfied at the ID stage, the EX stage proceeds
without doing anything. The next instruction also executes a fetch (figure 7.79).
