I'm not an expert on this at all, but I do have a nano-X application
running on NIOS (in fact a NEEK dev-kit). If you have a NEEK, to you
might want to try it, it's available in the Wiki as an Altera
Application Loader application.
Here I move a text window around on the screen. It uses about a quarter
of the screen and after the location change it in fact needs two
seconds for updating the screen.
I suppose the only way to speed this up is providing hardware support
instead of doing a "dumb" framebuffer. AFAIK, nano-X does support
hardware accelerated screens and it should be quite easy to to hardware
support for things like "blit" in the FPGA.
