Abstract

Embodiments allow a smaller, simpler hardware implementation of an input/output memory management unit (IOMMU) having improved translation behavior that is independent of page table structures and formats. Embodiments also provide device-independent structures and methods of implementation, allowing greater generality of software (fewer specific software versions, in turn reducing development costs).
