A time-wise hierarchy imposed upon the use of a two-level store

Abstract

Following general design principles a paging system has been developed in which has been aimed at high efficiency and a strong separation between store management and processor scheduling and a minimal influence of the program mix upon the system's performance. It is, furthermore, described how some dedicated hardware can be expected to contribute effectivel to memory management and the prevention of thrashing. Finally, the properties of the system should be such that a mismatch between configuration and workload gives a clear indication as to what reconfigurations seem indicated.
