ABSTRACT:
The method and apparatus for using the memory in an information processing system of the virtual addressing type is characterized in that a first memory domain DX is organized around a logical address of NX bits in size. In the memory domain DX, a plurality of address spaces EAX of identical structure is defined and relative addressing of a size NL less than NX is allowed. One of the address spaces EAX (hereinafter the current address space EAC) is assigned temporarily and interchangeably to a second memory domain DL organized around an address that is NL bits in size.
