PURPOSE:To decrease the overhead of a page, and to improve the utilization efficiency of a system by constituting a titled system so as to make plural pages containing a page which is the cause of interruption execute simultaneously page absence processing, when executing a page absence interruption processing. CONSTITUTION:When a program is being executed, a control is shifted to a code part 114, and the part 114 executes an access to the whole data part 115. At present, a part 301 and a part 302 show the code part 114 and a data part 115 (consisting of pages P1, P2...P5), respectively. In this state, the code part 301 executes an access first to the page P1 of the pages P1, P2...P5 of the data part 302, to which a page absence interruption PF is generated. In this case, from a management directory entry 135 of a management directory 103 for managing the page P1 which has become the cause of the interruption, it is known that the pages P2, P3...P5 except the page P1 are in a page absence state, and these pages P2...P5 are paged in simultaneously. In such a way, in the subsequent accesses P2, P3...P5, the page absence interruption is not generated. |
