Abstract
PURPOSE:To minimize a delay of a transmission time, by constituting a frame of the number of bits conforming with the transmission time of a data part required for mutual transmission of 2 system, and making transmission between differet kinds of data processing systems posible. CONSTITUTION:A transmission message from a system A is inputted to a receiving interface 1, is stored temporarily and also is checked. Its output is set to a control code decoder 2, and a control code is decoded ad also is sent to a message assembling part 5. Subsequently, in a control coe encoder 4, various control codes are generated and added to convert a transmission message format of the system A into a format of a system B, and its output is sent to the assembling part 5. Subsequently, in the assembling part 5, a data part required for the system B is received from in the message, also the code from the encoder 4 is received, is assembled for the system B, and is transmitted to the system B from a transmitting buffer 6.
