Abstract
PURPOSE: To execute easily a process of minimizing occupied areas by sectioning common-use resources into resources area for tree-shape systematization, by preparing a control table corresponding to each resources area and by controlling them by checking whether areas are occupied or not.
CONSTITUTION: To allow several processors to attain access to common-use resources stored on the main memory unit for their processes, the common-use resources are sectioned into resources areas A, B..., which are systematized in tree structure. Corresponding to respective resources areas A, B..., control table group 1 with control tables 1A, 1B... is provided in memory unit 2. Then, in-process indication information of one bit indicating that its own resources area is in process and a lower-area in-process count value expressing that an area lower than its own area is in process are prepared and at the time when one of data processors 4-0, 4-1... processes its own resources area or lower one, the process is inhibited with either in-process indication information or count value set.
