A matrix type bus connection system has a plurality of master devices and a plurality of slave devices. Each slave device has an arbitration circuit. The arbitration circuit stores an address of a master device that made the access the last time, and continues holding a select signal to a selector when access ends. If a new connection request is received, the arbitration circuit compares the address of the master device that is now making the access request with the address of the master device that made the access the last time. If the connection request is from the same master device, a connection control is not performed. The previous connection status is maintained. Thus, the master device can be connected to the slave device without a delay. |
