+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.
