Abstract
A method of conducting delayed data transaction on a PCI system and its associated devices. The delayed data transaction is carried out using a PCI system to transmit data between an initiator and a responder. Both the initiator and the responder are coupled to a PCI bus. The delayed transaction in the PCI system includes a number of steps. To begin with, the initiator will send out a request to use the PCI bus so that data transmission can be conducted with respect to the responder. If the responder accepts the request but unable to secure the requested data soon enough, the responder will generate a defer identifier that corresponds to the requesting initiator. Next, a stop signal and the defer identifier generated by the responder will be returned to the initiator, indicating that the request has been accepted. When the requested data is ready in the responder, the responder will forward the defer identifier again. The initiator picks up the defer identifier and prepares according to the buffer identifier in it. Then, data transmission between the initiator and the responder begins.
