1.2.2 Advanced Microcontroller Bus Architecture (AMBA)

The Cortex-A72 processor complies with the:

  • AMBA 4 AXI Coherency Extensions (ACE) protocol if the processor memory interface implements an ACE bus interface. See the ARM® AMBA® AXI and ACE Protocol Specification.
  • AMBA 4 Advanced eXtensible Interface (AXI) protocol for the Accelerator Coherency Port (ACP) slave interface. See the ARM® AMBA® AXI and ACE Protocol Specification.
  • AMBA 3 Advanced Peripheral Bus (APB) protocol. See the ARM® AMBA® APB Protocol Specification.
  • AMBA 3 Advanced Trace Bus (ATB) protocol. See the ARM® AMBA® 3 ATB Protocol Specification.
