| 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. |

| description: | |
| 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). |
