Abstract
A method includes providing an effective address, providing an address space identifier which identifies a currently executing process, providing a mapping modifier to form a modified address space identifier where the mapping modifier is based on at least one external signal generated outside the processor, using the effective address and the modified address space identifier to form a logical address, and providing a physical address corresponding to the logical address. When the effective address has a first effective address value, the address space identifier has a first address space identifier value, and the mapping modifier has a first mapping value, the physical address has a first physical address value. When the effective address has the first effective address value, the address space identifier has the first address space identifier value, and the mapping modifier has a second mapping value, the physical address has a second physical address value.
