阅读:75发布:2023-02-09

专利汇可以提供Disk access control system专利检索,专利查询,专利分析的服务。并且PURPOSE: To avoid a case where a segment having a high using frequency is undesirably swapped out by making a user set a swapping level as necessary onto a segment control block.
CONSTITUTION: A segment is loaded to a main storage 3 from an auxiliary memory device 4 in response to an access given from an end user 1. Then the correspondence is secured between the real and virtual address spaces on a block 6-i of a segment control table 5 provided in a cache mechanism 2. In this case, the priority set when the corresponding segment is swapped is defined as a swapping level and described on each block 6-i. A swap control mechanism 7 links the blocks to form a swapping queue based on said swapping level and the priority. Then the segment corresponding to the block set at the end of the swapping queue is swapped.
