They do have and my intention with "work with bunnie & Co" was to expand
on what they have. The status today is that it is incomplete, needs to
be documented, examples and guidelines written. This work also needs to
have HW interface developed for the specific FPGA in the Novena board to
allow easy hookup of cores. Something like coretest, but with shared mem
etc to allow high performance data exchange.

Yes, good idea. This really is smack in the middle of the green/blue
boundary. This actually implies that we probably will have more than one
implementation of the blue/green boundary. One for tightly
interconnected FPGAs and one for less tightly (say USB, Ethernet). This
can naturally be combined using wrappers but something we need to consider.

Good!

Yes. Good!
