MATCHING SYSTEM FOR INPUT MESSAGE OF DECENTRALIZED PROCESSING SYSTEM

摘要

PURPOSE:To increase the processing speed by securing such a system where each processor connected to a transmission line identifies the redundant ones out of those messages flowing the transmission line and no processing is required for said redundant messages. CONSTITUTION:It is decided whether the time stamp of a message fetched from a reception buffer 102 is coincident with the time stamp of another past input message having the same function code as the former message. In other words, the function code equal to that of the message fetched this time searches the row of an input/output data store area 105 set at an FC part in an input/ output data store area 105. Then the message supplied this time is not set to the area 105 and finishes its processing as it is since the message of this time is redundant to the past input message if it is decided that a time stamp coincident with that in the message fetched this time is stored in the time stamp area of the searched row.
