Abstract
Processing circuitry () performs processing in one of at least three domains (). Address translation circuitry () translates a virtual address of a memory access performed from a current domain to a physical address in one of a plurality of physical address spaces () selected based at least on the current domain. The domains include a root domain () for managing switching between other domains. The physical address spaces () include a root physical address space associated with the root domain (), separate from physical address spaces associated with other domains.
