Abstract
Abstract In a method for checking consistency of distributed data in which data distributedly stored in a plurality of devices connected to a common data transmission line are sequentially combined, each device sends out to the data transmission line output data accompanied with information indicating a position of a processed result in the output data, and the device which receives redundant data compares collected redundant data to select a correct data by comparing only the portion of the data which was lastly added in accordance with the information accompanying the data.
