Abstract
A bus arbitration scheme for controlling access or mastership of a bus is disclosed. Priority of access to the bus is based not only on the time relationship of the requests for use of the bus arriving at the arbiter but also on the relative priority of each request. Thus a higher priority request will gain access to the bus before a lower priority one even if this latter request arrived at the arbiter first. The arbitration scheme is implemented by a series of logic gates.
