Abstract
Systems and methods schedule periodic and non-periodic transactions in a multi-port bus environment. The method may comprise performing multiple search passes through a first array of endpoints to determine whether dispatch resources are available for active endpoints satisfying a set of sort criteria. When dispatch resources are not available for an endpoint, a sort level may be marked with a marker to indicate that an endpoint has not been serviced. After the active endpoints in the first array have been serviced by dispatching a periodic transaction to the endpoint or by marking a sort level corresponding to the endpoint, a non-periodic transaction may be dispatched to an active endpoint in a second array. In response to receiving an indication that the dispatch resources have become available, a subsequent search pass may be made through the first array, starting with a highest priority sort level that is marked with the marker.
