Logic Array as Serializer/Deserializer Interface
The design can use the lpm_shift_reg megafunction instead of a
simple dual port memory block to serialize/deserialize data. The receiver
requires an extra flip-flop clocked by the slow clock to latch on to the
deserialized data. The transmitter requires a counter to generate the
enable signal for the shift register to indicate the times to load and
serialize the data.

This scheme can also be used for APEX II and Mercury device flexible
LVDS solutions.
