Abstract
A data transmission system has multiple nodes connected to a common transmission medium. Each of the multiple nodes transmits data and the other nodes receive and store the data through the common transmission medium. The received data is read out for information exchange among the nodes. The node has transceiver circuitry for receiving a data frame and transmitting the data frame, receive and transmission control circuitry, receive data frame transmission control circuitry, a receive buffer, an external interface and address conversion memory circuitry. The receive and transmission control circuitry receives a data frame from the transceiver, detects whether or not the data frame designates that node and is received without errors, and transmits a data frame reception start signal and a data frame reception end signal. The data frame transmission control circuitry extracts predetermined received data included in the received data frame in response to the data frame reception start signal, and transmits the predetermined received data in response to the data frame reception end signal. The receive buffer receives and stores the predetermined received data, and the external interface provides a specific address. The address conversion memory circuitry stores an address of the received data stored in the receive buffer and converts the specific address into the address of the received data, thereby generating a conversion address. This considerably shortens the time required to transmit the received data, and improves data transmission speed in the whole system.
