It may be overkill for your requirements, but on V2 and V2Pro architectures you can implement the controller internally to the FPGA, and connect to the ICAP primitive. You can even connect it to a microblaze running either low level code or the Microblaze uClinux operating system. There is a core in EDK6.2 (and probably 6.3) called opb_xhwicap that accomplishes this. I posted a uClinux device driver for this device a few weeks ago. Attached is a paper I wrote earlier this year that talks about what you can do with it - it may be helpful or interesting to you. The group at Karlsruhe - Jurgen Becker et al, have also published work on self-reconfiguring systems using ICAP - they had a paper at this year's RAW workshop, that might interest you. Regards, John
