PURPOSE:To make the using priority of a common resource uniform by varying the priority of the common resource in accordance with the requesting state of respective processors. CONSTITUTION:The processors 2-4 are provided with flip-flops 40-42 as their storage means and a main memory device 5 is connected to the processors 2-4 in common. A receiving signal is transmitted to the processors 2-4 through receiving signal lines 11-12 which are signal transmission lines and then returned to the processors 4-2 through receiving signal lines 13-15 which are transmission lines. The FFs 40-42 are inverted at their state every input of the using right of the device 5, a receiving signal in one direction is used only for the processor having '0' FF value and a receiving signal in the reverse direction is used only for the processor having '1' FF value. |
