Abstract
PURPOSE: To utilize a common bus with a high efficiency by constituting a system so that each channel can be accepted through the common bus by connecting successively interrupt transfer lines and giving priority levels to I/O controller.
CONSTITUTION: In the system where plural I/O controllers 2-1 to 2-n connected on common bus 3 and CPU having microprocessor 1 are connected to perform the data transfer through common bus 3, interrupt signal transfer line 6 where plural controllers 2-1 to 2-n are connected successively in series is provided. Further, priority levels are given to controllers 2-1 to 2-n in the connection order to this transfer line 6, and interrupt signals are detected by interrupt control circuit 4 provided iun CPU, and sense signals are transmitted to interrupt signal transfer line 5. Then, on condition that interrupt signals are not generated from other controllers having priority levels higher than its own level and its own interrupt signal has been generated, each of controllers 2-1 to 20n transmits the channel to common bus 3 synchronously with sense signals
