B.5. Branch instructions

Branch instructions have different timing characteristics:

  • Branch instructions to immediate locations do not consume execution unit cycles.

  • Data-processing instructions to the PC register are processed in the execution units as standard instructions. See Data-processing instructions.

  • Load instructions to the PC register are processed in the execution units as standard instructions. See Load and store instructions.

See About the L1 instruction side memory system for information on dynamic branch prediction.
