Main memory control system

Abstract

Abstract PURPOSE:To reduce the memory capacity for storage by collecting plural dividing units of a main memory divided into the fixed number of dividing units to set a large-capacity dividing unit and managing the main memory in response to the capacity of a packed main memory. CONSTITUTION:A logical address 13 consists of a segment S, a page number P and an intra-page address L. A register 14 stores the real page numbers obtained from a segment table 15 and a page table 16 and a main memory access address merged with said address L. An indicator IND101 decides the presence or absence of a segment which controls a main memory in a large capacity unit. When a conventional page unit is decided, the RC bits are replaced by means of a real page number part of the register 14. While the main memory is managed in a large-capacity unit in the case of a large-capacity unit.
