Title: Data transferring system with priority control and common bus
IPC: G06F13/37
Filed: 1976-11-11
Abstract: A data transferring system having a plurality of devices using a common bus, wherein the devices send out a requesting signal to a requesting signal line for requesting a transfer of data, and in the devices a priority order is assigned to the transference of the data. The system further provides a common control unit for the plurality of devices so as to control the common bus by receiving the requesting signal on the requesting signal line and then sending an acknowledging signal for the transfer of data. Each of the plurality of devices receives the acknowledging signal so that the device which sends out the requesting signal carries out the transfer of data. At least one of the plurality of devices, except for the device having the highest priority order, has a detecting circuit for detecting the requesting signal on the requesting signal line. The device having the detecting circuit detects the requesting signal and prevents the sending out of the requesting signal from its own device and the device which is prevented from sending the requesting signal by the detecting circuit transfers the acknowledging signal to a following device. At least one of the plurality of devices, except for the device having the detecting circuit, is placed on the opposite side of the control unit with respect to the device having the detecting circuit.
