“For example, microprocessor degradation may lead to lower performance, necessitating a slowdown, but not necessary failures. In mission-critical AI applications, such as ADAS, a sensor degradation may directly lead to AI failures and hence system failure.”
This is probably a superficial analogy, but this made me think of people suffering from dementia in old age.
- Taek 6y agoDementia is actually a decent metaphor for what happens to an aging chip. Internally, a chip is extremely dependent on gate timings. As the chip decays, certain gates or wires will start to slow down or speed up, and the chip gets sloppier. Often, you can address the issue by slowing the chip clock rate down, because this gives you a much wider margin for error on your gate timings. Certain operations will be impacted sooner and more heavily than others. Eventually, the timings get bad enough that certain operations (or even the whole chip) just break altogether.
