Code Location

|
~~~~~~~~~~~~~
|
|
|
|
When designing a system there is a choice as to which hardware resources to use for each interface.
|
|
In a multi-tile system the codebase needs to be informed as to which tiles to use for these hardware
|
|
resources and associated code.
|
|
|
|
A series of defines are used to allow the programmer to easily move code between tiles. Arguably the
|
|
most important of these are ``AUDIO_IO_TILE`` and ``XUD_TILE``. :ref:`opt_location_defines` shows a
|
|
full listing of these ``TILE`` defines.

|
|
- Tile on which I2S, ADAT Rx, S/PDIF Rx & mixer resides
|
|
- ``0``
|
|
* - ``XUD_TILE``
|
|
- Tile on which USB resides, including buffering for all USB interfaces/endppoints
|
|
- ``0``
|
|
* - ``MIDI_TILE``
|
|
- Tile on which MIDI resides
|
|
- Same as ``AUDIO_IO_TILE``
|
|
* - ``SPDIF_TX_TILE``
|
|
- Tile on which S/PDIF Tx resides
|
|
- Same as ``AUDIO_IO_TILE``

|
|
- Tile on which PDM microphones resides
|
|
- Same as ``AUDIO_IO_TILE``
|
|
* - ``PLL_REF_TILE``
|
|
- Tile on which reference signal to CS2100 resides
|
|
- Same as ``AUDIO_IO_TILE``

It should be ensured that the relevant port defines in the application XN file match the code location defines
