1. A method comprising: dividing a physical address space into a plurality of segments; computing an interim first address from a physical address from the physical address space; computing an interim base value from a base value associated with the physical address; comparing the interim first address and the interim base value to determine whether the physical address can be validly translated to obtain a translated address; and if the physical address can be validly translated, combining the physical address with an offset value to obtain the translated address.
