Advances in formal software verification have produced an operating system that is guaranteed mathematically to be correct and enforce access isolation. Such an operating system could potentially consolidate safety and security critical software on a single device where previously multiple devices were used. One of the barriers to consolidation on commodity hardware is the lack of hardware dependability features. A hardware fault triggered by cosmic rays, alpha particle strikes, etc. potentially invalidates the strong mathematical guarantees. This paper discusses improving the trustworthiness of commodity hardware to enable a verified microkernel to be used in some situations previously needing separate computers.
