My understanding is there are two FCCs (flight control computers), but there is only one sensor package used for the MCAS. Normally separate sensor packages would feed into the separate FCCs and require agreement before taking action. I'm not sure why something that overrides pilot input wouldn't absolutely require multiple sensors monitored by the independent computers. My understanding is each computer is dual-CPU, though I'm not sure if they exclusively have each computer check the other or if each CPU checks its partner within the same computer (or both), and whether that applies to all tasks or just some of them.
