Patent attributes
A multiprocessing method suitable for realizing satisfactory online processing by synchronizing data processing in respective element processor nodes in spite of a loosely coupled system used with the plural element processor nodes driven with individual clocks, the method is characterized in that the plural element processor nodes driven with the individual clocks and an information transfer medium through which the respective element processor nodes provide and acquire data each other are used, the respective element processor nodes start cyclic data processing according their own judgment at timing of providing or acquiring trigger data, perform predetermined calculation after acquiring the input data from the data source so as to provide calculation result into the information transfer medium, and acquire a plurality of calculation result provided by other element processor nodes from the information transfer medium to determine operation result obtained from the plural calculation result through logical decision as output data, thereby outputting the output data into the output target from any one of the element processor nodes having the output data.
