ABSTRACT:
Partitioning, paging, and segmentation techniques are employed with virtual memory to provide more secure and efficient storage and transfer of information. The virtual memory is divided into a plurality of partitions with real memory storage provided by paging the plurality of partitions. User programs are segmented into logical units and stored in assigned partitions thereby isolating user programs and data. Unsegmented programs may be run by storage in a partition with direct addressing. Segment descriptors including partition, base, and bound are utilized in accessing memory. User domains are expandable by temporarily passing descriptor parameters from one routine to another with access flags limiting access thereto. By shrinking passed descriptors the receiving routine can be restricted to only a portion of the information defined by the descriptor.
