ABSTRACT:
A multiprocessor system in which a single operating system is controlled by a number of central processing units. The system allows the expansion of its virtual memory without major modifications the operating system. The system utilizes two virtual memories, one with a larger memory capacity than the other. Each memory is controlled by a space control section, which, in turn, is connected to an associated central processing unit. A first program is executed by both space control sections, while a second program is operated by only one of the space control sections. The second program is stored in the second virtual memory, in an area of the second virtual memory not overlapping the area of the first virtual memory.
