In practice such a hard realtime guarantee can only be met by a devices like an FPGA. There have always been fully deterministic CPUs around for that purpose.

There have always been fully deterministic CPUs around for that purpose. The simpler the system, the better; just hook a Forth chip to a memory without caches and you're set.
- doelie_ 13y agoDo you have any experience with Forth chips? I've been looking for an excuse to play with the GreenArray devices.
- gngeal 13y agoNo, but I don't see any flaw in that design. Indeed, it seems like the case of Hoare's "obviously no deficiencies" in a system design. I believe that the GreenArrays people, setting aside the $450 dev board, also had some notes on making cheap breadboards with their chips or something like that. I don't have a link handy, though. ;/
- ballard 13y agoCould try calling their sales folks and see if a rep will just sample it.
