Abstract
A data processing system includes a plurality of nodes connected to a shared data path, one of said plurality of nodes being a commander node to initiate a transaction on said shared data path, and one of said plurality of nodes being a responder node. The system also includes means for providing, by said responder node, a response to said commander node indicating unavailability of said responder node and for providing an acknowledgement of said transaction over said shared data path; and means, directly responsive to said response indicating that said responder node is unavailable to respond to said transaction, for retrying said transaction. In this manner, a retry mechanism can be implemented on a bus which does not directly support a retry signal.
