Abstract
A competition arbitration system in which chances for using a resource of a computer such as a bus or the like among devices are fair is provided. Pulses are sequentially generated periodically from a pulse generating circuit. It is assumed that first device outputted first bus request signal and second device continuously outputted second bus request signal before rising timing of the first pulse. When a bus arbiter outputs a bus grant signal to the first device at the rising timing of the first pulse, the bus master of the first device outputs a bus use acknowledgment signal. Then a use grant inhibiting circuit receives the acknowledgment signal and outputs an inhibition signal for inhibiting use of other devices. Thus, the first device holds the use right of a bus and bus use requests of other devices are reserved.
