Abstract

PURPOSE:To execute access processings in the order of access requests, by performing the priority level determination processing in respect to access requests from the same access request device after another access processing device starts the access processing. CONSTITUTION:Access requests outputted continuously from access request devices 2-0-2-n are accepted and processed successively by access processing devices 3-0 and 3-1, and the requirements for the entry into the priority level determination processing performed before the start of the access processing are determined on the basis of presence or absence of access requests to its own access processing device and that of access requests to the other access processor. Therefore, access requests outputted continuously are accepted successively, and the access processing for the latter access request is prevented from being performed before the access processing for the former access request.
