Normally in a control system if you want to build a truly fail safe control system then mere duplication and verification does not always work. What you need is a two-out-of-three kind of a system where the system always have three set of signals, variables or such things. The fault cheeking system will verify whether at least two of these three signals are matching. If they match then the control system is said to be working fault free else it is declared as faulty.

Good to know that as more eletronics goes into cars more safety and reliability is included. When my car has joined an autobaun 'train' I will feel a bit better trusting the automatic drive mode. Think of all those lines of code that need to function correctly...

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
