Would've been cool for safety applications if the second core could be run in lockstep mode.

- 4gotunameagain 2y agoafaik that is a whole different rodeo on the silicon level
- KaiserPro 2y agoyeah lockstep requires a whole bunch of things to verify and break deadlocks. I suspect you need three processors to do that as well (so you know which one has fucked up.)
- 4gotunameagain 2y agoIt is not necessary that there is triple modular redundancy with lockstep, I know of microcontrollers with two processors, who throw an error when the results from instructions don't match.
