[Oberon] New FPGA Oberon board

[Walter Gallegos]

Let me try to explain my point of view, build a FPGA board with resources 
only to implement a CPU is not a good idea. Is like build a car with great 
engine but 10Lts fuel tank, we can't go to far with this car.

Implement the RISC5 into a very low end FPGA as Spartan-3 is excellent to 
show the virtues of the project but has not many practical uses because 
implement a CPU with logic farms is not cheaper.

The real power of FPGA is their capacity to implement signal processing in 
hardware; so, how many of the logic farm and others resources rest free 
after implement the RISC5 into a low end FPGA ?

As hardware developer is very interesting have additional resources to 
implement filters, FFT, DSP, video processing and so on in hardware to be 
attached to RISC5 as peripheral or coprocessor. This is the way to implement 
modern SoC, with custom hardware and software cooperation.

Best regards,
Walter

Saanlima's current two-board Pipistrello Spartan-6 Oberon FPGA system with
1MB of fast SRAM sells for just under than $US195. Magnus states on his
forum "...it would be much cheaper to make a new board with all the features
needed but not more". To me that says that $US 150 is certainly a
possibility. That sort of system would suit me fine - the only extra I need
is the ability to connect the board via RS232 to a PC,
