ABSTRACT:
A displacement segmentation memory management system is based on physical segmentation space allocation. A program is divided into segments defined by the physical memory space available. One or more segment descriptor table is created for each task. These may be divided into groups. The virtual address for a data word in a program is translated into the physical address in the following way. The virtual address is compared with entries on a limit table. The matching limit entry determines the proper segment entry. The proper segment value is added with the virtual address to determine a proper address block. This address block is concatenated with the page offset field to generate a physical address of the requested data.
