Since the quite old Spartan-6 FPGA is used on Cute-WR-DP; the Cute-WR-A7 replaces the FPGA with much newer Artix 7 family.
The Cute-WR-DP is the enhanced version of
Cute-WR with dual WR ports.
There are three operation modes for Cute-WR-DP.
The firmware is based on WRPC with modified code in the LM32 softcore.
The additional resource cost to support Dual Port is less than twice
that of a single port.
