This could be done using synthesizable CPU cores for FPGAs (or if someone
with deep pockets want to make a 'Vectorcade ASIC'....yeah right :) ! )
There is a free synthasizable 6502 core available now at
http://www.free-ip.com
Right now, the way this 6502 is designed, any 'cheap' FPGA is out of the
question. From what I can tell, it uses FPGAs that have embedded memory
elements (i.e. blocks of memory you can configure as RAM or ROM), or needs
a ton of flip flops since it employs a microcoded control unit.
Also, the CPU does not yet have BCD arithmetic implemented yet. However,
it's a good start and the designers claim it's working perfectly despite
the absence of BCD math. They've also added a multiply operation.
In either case, it's a start! If you go out and purchace 6502 cores, you
have to spend a bundle ($10K on up + royalties in some cases).
Current, cheaper FPGAs are really nice for the Cinematronics CPU ;) ....
