.. 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::
|
|
|
|
The ULPI ports are a fixed set of ports on the L-Series
|
|
device. When using these ports, other ports are
|
|
unavailable when ULPI is active. See the `XS1-L Hardware Design Checklist <http://www.xmos.com/published/xs1lcheck>`_ for further details.
