Features and Enhancements
2.1.1.1 Instruction Fetch Pipeline (IFP)
The IFP generates instruction addresses and fetches. Because the fetch and execution
pipelines are decoupled by a 3 longword FIFO buffer, the IFP can prefetch instructions
before the OEP needs them, minimizing stalls.

• Two-stage IFP (plus optional instruction buffer stage)
• Two-stage OEP
— Instruction address generation (IAG) calculates the next prefetch address.
— Instruction fetch cycle (IC) initiates prefetch on the processor’s local instruction
— Instruction buffer (IB) optional stage uses FIFO queue to minimize effects of
— Decode, select/operand fetch (DSOC) decodes the instruction and selects the
