Custom Computation Device
Hey all,
It's the weekend and I have nothing better to do than daydream about putting together a custom Computation device (not a PC). Nothing is likely to result from this but I find it interesting to think about it. It would be a basic system, little more than a minimal-system that uses machine-code stored in an EEPROM to perform Fermat-Tests. I did put together a programmable Z80 system about 30 years ago and designed a NDT system from a basic FPGA unit (with no embedded CPUs) about 15 years ago. The 1st step would be to wire up a CPU minimal-system and proceed from there. Things must have progressed significantly since my last ventures in electronics. What CPUs or FPGAs would you recommend for such an application? Thanks in advance.

Because you could manually wire up a PIC system. These are very weak CPUs and can't do much, but they do come in hobbyist DIP packages if you want to play. Otherwise anything with some actual computation grunt will necessarily come in a BGA package and require somewhat better tools than a soldering iron and a multimeter. You could look at some of the pre-made boards (beagle board, Gumstix, Logic-PD, etc.) to get you started with something basic. |

Thank you for the reply retina.
The surface-Mount chips are out of my prototyping capabilities. Having large number of data-pins is ideal for processing large numbers. I will be looking into the starter boards that you mentioned. Thanks again for the reply. |

I would also look at the design of things like the BBC Microbit or Arduino boards to get an idea of what other people have done in this area.
