Abstract
An apparatus has address translation circuitry to translate a target virtual address (VA) specified by a memory access request into a target physical address, first/second translation table address storage circuitry to store first/second translation table addresses; and protected region defining data storage circuitry to store region defining data specifying at least one protected region of virtual address space. In response to the memory access request: when the target VA is in the protected region(s), the address translation circuitry translates the target VA based on address translation data from a first translation table structure identified by the first translation table address. When the target VA is outside the protected region(s), the target VA is translated based on address translation data from a second translation table structure identified by the second translation table address.
