A self-control type bus arbitration circuit and an arbitration method are disclosed, in which a bus arbiter is not needed, but entities commonly connected to a bus share 3 kinds of information, so that the entities can arbitrate the bus ownership use for themselves, and can occupy the bus in accordance with the priorities without mutual conflicts. Further, in order to solve the problem of the limit in the number of the sharing entities, the entities are made to use a clock information contained in the 3 kinds of information, i.e., the clock, the reference pulse and the in-use signal information, in such a manner that the clock is multiplied by an integer within the entities.
