摘要： In accordance with the present invention, a resource allocation array has at least one resource input line (Aj), at least one request for resource input line (Ri) and at least one cell (12) coupled to the at least one resource input line and to the at least one request for resource line. The resource allocation array assigns one resource to one request for the resource. The one resource and the one request for the resource are both of a group of at least one resource and of a group of at least one request for the resource, respectively. The availability and unavailability of the resource is represented by a first and a second predetermined resource signal, respectively. The assertion and non assertion of the request for resource is represented by a third and a fourth predetermined request for resource signal, respectively. The at least one resource input line is associated with one of the at least one resource signals. The at least one request for resource input line is associated with one of the at least one request for resource signals. The cell generates a predetermined signal, toggles the resource signal from the first to the second predetermined resource signal, and toggles the request for resource signal from the third to the fourth predetermined request for resource signal if the one resource signal and the one request for resource signal correspond in logic state to the first and to the third predetermined signals, respectively.
