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