Arbitration requests are received that belong to respective bus types. Each of the types is associated with a programmed value representing a potential number of times that requests of that type may win arbitration events that occur in a given time period. For at least some arbitration events that occur in the given time period, the invention updates a counter value for at least some of the types, the counter value for each of the types being set initially to the programmed value, and chooses a winning type in each of the arbitration events based on at least some of the counter values of the types of requests that are contending in the arbitration event.
