Abstract
A packet communication system suitable for a high speed bus, and a method of controlling the system. A data bus is divided into a control bus for receiving data for contention control and a transmission bus for receiving only communication data including destination data. Each terminal interface transmits the contention control data to the control bus in the transmission cycle prior to transmission of its packet to perform contention control. Thus, exclusive occupation authority of the transfer bus is acquired prior to packet transmission. Each terminal interface finishes the contention control in the cycle prior to the data transmission cycle to previously make a reservation for the use of the bus, and outputs the packet following the DLA onto the transmission bus in the next data transmission cycle.
