This is the kind of stuff I'm talking about. Maybe the design space didn't win, but it would be really fun to explore.

Another project could be to modify the caddr verilog to match the LMI hardware, they have a slightly different MMU. The LMI software stack is complete and can rebuild itself.

I chose to emulate the OpenCores ethernet controller in the CADR software emulator to make it easier to move images between software and FPGA implementations.

Do you have a reference for the LMI hardware? That sounds like a good starting point, especially if the software exists already for the LMI hardware.

Maybe easiest to look at the sources for the emulator, I posted a link to it in another comment.
