Abstract
A system for accessing contents of the directory structure in a computing system having a CPU and implementing indirectly addressable main memory via a first directory structure included in the memory. In this system, CPU generated real memory addresses are translated to one or more physical memory locations using the directory structure. A second directory structure is provided in main memory that includes one or more entries with each entry formatted to provide addressability to a predetermined number of entries in the first directory structure. The second directory structure alternately may access all contents of main memory, and is adaptable as main memory capacity varies. The second directory structure may alternately be implemented as a hardware device which computes the addresses for accessing data in main memory.
