ABSTRACT:
A plug-in logic board for use in an arbitration mechanism is disclosed. The disclosed arbitration mechanism includes two or more request processing units, two or more grant processing units and a common broadcast medium. The request processing units and the grant processing units use the common broadcast medium to control the coupling between requesters and resources on a first come, first served basis. The disclosed logic board includes a request processing unit coupled to the common broadcast medium, a grant processing unit coupled to the common broadcast medium, and an input/output unit coupled to an electronic operating device. The input/output unit passes a resource type request signal from the electronic operating device to the request processing unit, and passes a status signal received from the electronic operating device to the grant processing unit. The input/output unit further outputs a grant signal received from the request processing unit to the electronic operating device. The disclosed logic board further includes a means, responsive to said resource type request signal, said status signal, and said grant signal, for coupling a requester type electronic operating device to a resource type electronic operating device using a resource access path.
