Instruction Issuance
These instructions use the branch pipeline.

BF
Branch destination
The branch destination address is calculated in the EX stage. All overrun-fetched instructions
up to that point are discarded. The branch destination instruction fetch is started from the slot
following the instruction A EX stage slot.
If it is determined in the ID stage that the condition is not met, processing proceeds with
nothing done in the EX stage. The next instruction is fetched and executed.
A typical pipeline is shown below.
If the preceding instruction is a CMP instruction, execution is delayed by 1 cycle.
If the preceding instruction is a single-precision FCMP instruction, execution is delayed by 2
cycles.
If the preceding instruction is a double-precision FCMP instruction, execution is delayed by 3
cycles.
