That is exactly the thing though.
If you could reduce a digital control unit to a small program and run that on a write-once memory in a dead simple controller, you'd avoid spectre, meltdown, you'd avoid the vulnerability of overwriting the program post-deployment and you'd simplify ensuring correctness of the control program. Verification might actually be possible there.
- laythea 8y agoHi, yes but they wont do that. Normally, there is no write once memory. Most eg. oil rig control systems are not hammered down to that level. Heck - most aviation flight control systems are not like that. In fact, I was, in my early career responsible for writing a windows C# communications driver for the entire oil rig. Its still working :)
