摘要:
An information processing system managing a virtual memory by using a real memory system comprising a single or a plurality of processors which, when a real page allocation request occurs in a processor or task keeping the use priority that the real pages of a group among the divided groups of the real pages of said memory can be used in a priority basis, allocated the real pages belonging to said group for which said processor or task keeps the use priority to said processor or task in a priority basis so as to decrease the cache cancel rate and the mapping fault occurrence rate and to allow for smoothing and high speed access of the main memory.
