Yes. This is a well known problem. See (https://en.wikipedia.org/wiki/Arbiter_[electronics]). It's not possible to build an arbiter which will reliably decide who wins in a fixed time. It is, however, possible to design one which can detect that the arbiter hasn't stabilized yet and delays until it has. All multiprocessor shared-memory systems need this. |
