Abstract:
Access control circuitry comprises: a detector to detect a memory address translation between a virtual memory address in a virtual memory address space and a physical memory address in a physical memory address space, provided in response to a translation request by further circuitry; an address translation memory, to store data representing a set of physical memory addresses previously provided to the further circuitry in response to translation requests by the further circuitry; an interface to receive a physical memory address from the further circuitry for a memory access by the further circuitry; a comparator to compare a physical memory address received from the further circuitry with the set of physical addresses stored by the address translation memory, and to permit access, by the further circuitry, to a physical address included in the set of one or more physical memory addresses.
