Abstract
A memory management unit comprises an interface for receiving an address translation request from a device, the address translation request specifying a virtual request to be translated. Translation circuitry translates the virtual address into an intermediate address different from a physical address directly specifying a memory location. The interface provides an address translation response specifying the intermediate address to the device in response to the address translation request. This improves security by avoiding exposure of physical addresses to the device.
