ABSTRACT:
A microprocessor includes a processing unit, an address bus connected to an addressable memory space, and executes instructions from an instruction set for accessing the addressable memory space. The addressable memory space is for a lower memory area and an extended memory area. The instruction set includes a first instruction group for accessing the lower memory area, and a second instruction group that is distinct from the first instruction group for accessing the extended memory area.
