+description: |
+ The Audio Multiplexer (AMX) block can multiplex up to four input streams
+ each of which can have maximum 16 channels and generate an output stream
+ with maximum 16 channels. A byte RAM helps to form an output frame by
+ any combination of bytes from the input frames.

+ AMX has four inputs and one output. Accordingly ACIF (Audio Client
+ Interfaces) port nodes are defined to represent AMX inputs (port 0
+ to 3) and output (port 4). These are connected to corresponding
+ ports on AHUB (Audio Hub).
