Physical address provision method for processor system with virtual addressing uses hierarchy mapping process for conversion of virtual address

摘要

The physical address provision method uses a mapping rule in the form of a hierarchical tree structure with compressed nodes for conversion of a virtual address into a physical address, with initial reading of a compression indicator contained within the mapping rule, before reading a section of the virtual address assigned to the node level under consideration, for obtaining a node list entry from which the physical address is determined directly. Also included are Independent claims for the following: (a) a device for provision of a physical address from a virtual address using a hierarchy mapping process; (b) a processor system with a device for provision of a physical address from a virtual address using a hierarchy mapping process
