PURPOSE:To attain high speed calling processing by providing a file area for plural buffers formed in each file memory of each processor and a directory table for managing the file formed in each main memory and access controlling the file in the file memory under the management of the directory table. CONSTITUTION:When a certain access request is generated, it reaches through processing request section interfaces 12'(X), 13'(Y) to a file memory (FM) input and output control system (IOCS). An FMIOCS cooperates with a main memory (MM), FM, fm1, fm2, and a directory table., The main memory MM includes an area for storing a data temporarily which is transferred from an indirect connecting device (CCA)IOCS(X) and a transferring area. The directory stable comprises a directory head pointer DP, a priority directory D1, and a general directory D2, and is diposed in the main memory MM. Areas TS1 and HA1 designate the directory D1 and the areas TS2, HA2 designate the directory D2. Further, according to a file number FLO, they jump to predetermined positions. |
