Maybe because the physical chip itself has not been verified to operate correctly under various noisy conditions (x-rays, magnetic fields, cosmic ray errors...)

Maybe because the physical chip itself has not been verified to operate correctly under various noisy conditions (x-rays, magnetic fields, cosmic ray errors...). E.g. launch computers like this [1] would use redundant circuits with majority voting, and even redundant voting logic.

- MaxBarraclough 6y agoPerhaps. I'm surprised that article doesn't mention radiation. You're right of course that radiation-hardened chips are a very specialist area. Not often you can charge hundreds of thousands of dollars for a single CPU chip running at 200MHz or less. https://en.wikipedia.org/wiki/RAD750 https://en.wikipedia.org/wiki/RAD750
- rbanffy 6y agoI'm really curious about the processes used to make these. Part of it is because it uses huge features, of course, but I wonder if there are other things to it such as the materials and the encapsulation.

- rbanffy 6y agoIt has the IEEE logo. Looks expensive.
- a1369209993 6y agoSure, that makes sense, but: > why single out life-support systems and implants? Would it be meaningfully different if it were used in avionics, or industrial safety systems? Or any other "life critical applications"?
- kube-system 6y agoMy guess is that "life-support systems" is what immediately came to mind when their legal council was contemplating potential realms of excessive liability.
