Abstract: A pipelined data processing system (10) includes an address generation unit (30). The address generation unit (30) includes a target address register (58), a short backward branch (SBB) address register (60), and a count register (74) that makes the execution of small loops more efficient and allows branch folding without fetching the branch instruction.
