Abstract:
The described embodiments include an input-output memory management unit (IOMMU) with two or more memory elements and a controller. The controller is configured to select, based on one or more factors, one or more selected memory elements from among the two or more memory elements for performing virtual address to physical address translations in the IOMMU. The controller then performs the virtual address to physical address translations using the one or more selected memory elements.
