摘要： 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.

摘要： A delayed transaction method and system to handle multiple delayed transactions in a PCI system is disclosed. When the responder accepts a first and second request from an initiator but can not immediately respond to the first and second request, the responder generates a first and a second defer identifier corresponding to the initiator, respectively. When data transfer between the responder and the initiator corresponding to the first request is completed and data is ready for transfer corresponding to the second request, the responder immediately issues a second buffer identifier along with the data requested corresponding to the second request. Thus, data transfer between the initiator and the responder based on the second buffer identifier corresponding to the second request can proceed.

摘要： A processing method, a chip set and a controller for supporting message signaled interrupt. A memory write transaction on a PCI bus is monitored. When the address of the system memory specified in the interrupt message of the write transaction is located at a range of a reserved interrupt address, the interrupting service sequence is performed. The reserved interrupt address is located in an address of a system memory. Thus, the data to be processed and the system-specified message are written in the buffer and arranged in sequence. The problem of “write buffer latency” is resolved, and is irrelevant to the level of the PCI bus. Many system specified messages can be stored in the system memory, so that multiple system message signaled interrupts issue from different peripheral components can be processed in the same interrupt service routine.

摘要： A data transaction method between control chips. Data buffers of the control chips of the control chipset have fixed size and amount. In addition, read/write acknowledge commands are asserted in sequence according to read/write commands, by which the control chips can detect the status of the buffers within another control chips. When a control chip asserts a command, the corresponding data must be ready in advance. Therefore, the signal line for providing the waiting status, data transaction cycle and stop/retry protocol can be omitted. Accordingly, commands or data can be continuously transmitted without waiting, stop or retry, the performance is improved.

摘要： Method and apparatus for arbitrating access to a pci bus by a plurality of functions in a multi-function master. The arbitrating method is performed among the multiple functions of a multi-function master. The arbiter includes a rotating inquiry scheduler (RIS) and a heuristic inquiry initiator (HII). The RIS receives the local inquiry signal from the functional circuit and stores it. According to the local inquiry signal, a bus inquiry signal is generated and sent to the HII, and is sent to the PCI bus to request a use of the PCI bus. If the PCI bus responds a delay transaction termination, the HII can repeatedly send the bus inquiry signal to the PCI bus until the PCI bus grants the privilege to use the PCI bus. The HII then informs the RIS, which arranges the functional circuit to transmit data through the PCI bus.
