Abstract
PURPOSE:To reduce the transmission delay of data as well as the load given to a relaying information processing part, by adding a data input/output terminal and a clock terminal to the master and slave information processing parts respectively and connecting these two terminals to a bidirectional serial data line and a clock signal line respectively so that data can be transferred directly between the slave information processing parts. CONSTITUTION:Then a slave information processor A transmits data to another information processing part, the transmitting part of the part A confirms whether a bidirectional serial data line is kept under a busy or non-busy state to turn the non- busy state into a busy state. Thus a clock signal transmitting circuit of a master information processing part transmits a clock signal to a clock signal line. The transmitting part of the part A sends a transmitter identification code to the bidirectional serial data line to show the transmitter synchronously with the clock signal received from the master information processing part. While a transmission control part of the part A compares the signal transmitted from the transmitting part with the signal received by the receiving part from the bidirectional serial data line. Then various control signals are sent to the transmitting part when the number of discordant bits exceeds a reference level.
