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.
