It has been a while since I done this so please excuse any mistakes!

I interfaced some custom and some generated IP to a MicroBlaze by using the Fast Simplex Links (FSLs). I thought they looked the easier bus to use in the limited time I had for the project.

You have to write your IP to conform to the FSL interface, or you can put the IP in a 'wrapper' that makes it compliant.

With the Xiilnx software you can generate a FSL IP and start from there.

At one point I got frustrated with the FSLs and was going to route everything off the FPGA and back in using GPIO Very Happy
