ABSTRACT:
A method and apparatus are provided for enabling a computer that is capable of running programs utilizing different address sizes to run those programs without having to modify the computer's hardware. A mask register is used to identify bits of a sum of register addresses that are valid for the program that is running. The number of valid bits in the register mask can be changed to correspond to the addressable memory size for different programs.
