You are refering to the ip core in the fpga? Till now - I think - there
is no ip core used, because the plb will be built in the next time by
another student, who is working on the fpga-part.
So I'm just trying to find out, the best way to communicate between
fpga and linux in order to realize the functions I described above.
Any information how to solve that issue would help me.
