I see you fight for flexibility and compatibility issue. Usually when such problem is more important than performance (in power, space or speed), you put a CPU.
Maybe you could put a strip down LEON cpu (a spark like) and use there caches as memory. Thos memory could be loaded at boot time from an eeprom. This cpu will only act as a supervisor and is mainly dedicated to control the datapath from a very high point of view. If LEON is too big, a 8 bits microcontroler could do the job. LEON take 5k virtex FPGA cells. It's roughtly the speed of an ARM9. Compare to the GPU, it could a tiny add that enable a lot of flexibility. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
