JPS6462752A - Dynamic constitution control system - Google Patents

Abstract

PURPOSE:To safely change the constitution of a system at high speed without suspending an operation of the system, by providing an equipment construction control signal conducting means for executing interruption or conduction of an equipment construction control signal by which each device command an access of equipment construction information to a memory controller, by a command being independent from the command. CONSTITUTION:Before executing the command of conduction related to all control signals with respect to a control signal conducting means 4n provided in a memory controller 2 of a device in, the command of conduction related to a control signal required for executing an access to equipment construction information of a device in a main storage device 3 is executed in advance to an equipment construction control signal conducting means 5n. Accordingly, based on the control signal, write or read-out related to the equipment construction information is executed, and the device 1n becomes a connected state to the memory controller 2 as a hardware. Thereafter, the command of conduction related to all the control signals sent and received between the device 1n and the memory controller 2 is issued, and they become completely a connected state as a software, as well. In such a way, the device can be integrated at high speed and safely when the system is being operated.
