DECENTRALIZED PROCESSING SYSTEM OF INFORMATION

摘要

PURPOSE:To lower the occupying factor of circuit and to improve the processing capacity of an information processing system consisting of a controller and plural input/output devices, by storing previously the information having high using frequencies dispersedly even to the input/output devices. CONSTITUTION:A controller 1 is connected to plural input/output devices 3 via a communication circuit 2. The controller 1 registers the data of all information and their indexes to a table 10 together with the addresses of information which are decentralized to the input/output devices 3. Each device 3 has a table 20 which stores the information of a high using frequency along with its address in response to the property and the type of the device. The controller 1 decides the necessity for transmission of information and transmits only necessary information to each device 3. Thus the device 3 receives only its lacking information from the controller 1. This process lowers the occupying factor of a circuit and improves the processing capacity of a system as a whole.
