Resource Usage
|
|
--------------
|
|
|
|
The following table details the resource usage of each component of the reference design software.
|
|
Note, memory usage is approximate and varies based on device used, compiler settings etc.

.. note::
|
|
|
|
These resource estimates are based on the multichannel reference design with
|
|
all options of that design enabled. For fewer channels, the resource
|
|
usage is likely to decrease.
|
|
|
|
.. note::
|
|
|
|
The XUD library requires an 80MIPS core to function correctly
|
|
(i.e. on a 500MHz part only six cores can run).
|
|
|
|
.. note::
|
|
|
|
Unlike other interfaces, since the USB PHY is internal the USB ports are a fixed set of ports
|
|
and cannot be modified. See ``lib_xud`` documentation for full details.
