title: Tegra210 ADX

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).
