+description: |
+ The Audio Demultiplexer (ADX) block takes an input stream with up to
+ 16 channels and demultiplexes it into four output streams of up to 16
+ channels each. A byte RAM helps to form output frames by any combination
+ of bytes from the input frame. Its design is identical to that of byte
+ RAM in the AMX except that the data flow direction is reversed.

+ ADX has one input and four outputs. Accordingly ACIF (Audio Client
+ Interface) port nodes are defined to represent ADX input (port 0)
+ and outputs (ports 1 to 4). These are connected to corresponding
+ ports on AHUB (Audio Hub).
