A ring connection which has been used for connecting processors connected far from each other, is improved in latency, throughput and operational function and is applied to attain high speed connection between processors. A plurality of modules such as processors are connected with rings having a plurality of signal lines. An independent signal line for a flag for acquiring a transmission right is provided. A transmission right is requested by setting the flag, and reception and transmission operations and transfer operation in the ring are operated in parallel by confirming later the advance acquisition of the transmission right based on the detection of no setting of the received flag.
