Section 8 Pipeline Operation
(3) Unconditional Branch Instructions
Instruction Types
Pipeline
Operation
The pipeline ends after three stages: IF, ID, EX. Unconditional branch instructions are delayed
branch instructions.
The branch destination address is calculated in the EX stage. The instruction after the
unconditional branch instruction (instruction A) – that is, the delay slot instruction – is not
discarded after being fetched, as with a conditional branch instruction, but is executed. However,
the ID stage of this delay slot instruction is stalled for a 2-slot interval. The branch destination
instruction fetch is started from the slot following the instruction A EX stage slot.
Interrupts are not accepted in the delay slot.
Instruction Issuance
These instructions use the branch pipeline.
If an instruction fetch has not yet been performed for the instruction (delay slot) immediately
following one of these instructions, execution of that instruction is delayed.
