Thats what OGP is about right? Create a graphics card that avoids
patent encumbered technology. Even if that means trying new techniques
and api's.
Right!
Given the current non-OGD threads on this open-graphics list, though,
I'm worried that OGD may not come to pass. :(
Can we do the same for the whole system? Maybe a crsossover switch
based system?
No idea what you mean by crossover switch, but its certainly possible to
do an entirely open PC.
opencores.org already has most of the pieces. Mainly, someone needs to
tie all the disparate pieces into a single southbridge, PC-ready chip.
You could even glue the 8-core, 4-thread SPARC Niagara (Verilog is
GPL'd) into an open system.
Another option specifically for graphics is to hack opencores' OpenRISC
1200 to include graphics-specific floating point types. Ready-made GPU
solution! OpenRISC has already been validated in ASIC and FPGA (though
without graphics-specific FP types, obviously).
