    7 title: NVIDIA Tegra ACONNECT Bus
    8 
    9 description: |
   10   The Tegra ACONNECT bus is an AXI switch which is used to connnect various
   11   components inside the Audio Processing Engine (APE). All CPU accesses to
   12   the APE subsystem go through the ACONNECT via an APB to AXI wrapper. All
   13   devices accessed via the ACONNNECT are described by child-nodes.
