Abstract

PURPOSE:To attain coincidence of common data without any designation by ORing exclusively the common data and an update data ahead the transmission of a data and transmitting the result. CONSTITUTION:When a transmission request is given from a function at the transmission side, an exclusive OR circuit 2 ORes exclusively the revised data and the trasmission side common data area 1 and transmits the result to a receiver via a transmitter 3. At the reception side, the received data and the reception side common data area 6 are ORed exclusively at the exclusive OR circuit 5 at the reception side and the result is stored again the reception side common data area 6.

タを一致させる。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention provides an exclusive OR of the common data and the update data on the transmitting side when updating data between two devices that have common data on both sides. The result is transmitted, and the receiving side performs an exclusive OR of this data and the common data to make the common data of both the sending and receiving sides match.

〔発明の背景〕[Background of the invention]

送受双方に共通データを有し、同一の値とする２つの機
器間のデータ更新において、更新する部分と更新しない
部分とを明確にするマスク情報を作成し、更新する情報
に添え、送信せねばならないという欠点があった。When updating data between two devices that have common data and the same value for both sending and receiving, mask information that clarifies the parts to be updated and the parts not to be updated must be created and sent along with the information to be updated. There was a drawback that it was not possible.

ることにある。An object of the present invention is to transmit and receive data from any location to any location within a pre-specified range without specifying the location or length in data transmission and reception between two devices that have common data that indicates the same value on both sides. The purpose is to update the value to a common value for both sending and receiving.

〔発明の概要〕[Summary of the invention]

送信側では、データの送信に先立ち、送信側の共通デー
タと更新データとの排他的論理和をとり、送信データを
作成して送信する。On the transmitting side, prior to transmitting data, the common data on the transmitting side and the update data are exclusive-ORed to create and transmit data to be transmitted.

受信側では、転送されて来たデータと受信側の共通デー
タとの排他的論理和をとり、新しい共通データとする。On the receiving side, exclusive OR is performed between the transferred data and the common data on the receiving side, and the result is new common data.
