    摘要: An expansion adapter is used to communicate both PCI and AGP devices to the north bridge chip of a computer. The expansion adapter includes a first AGP bus control module communicable with the north bridge chip via a first AGP bus, and a second AGP bus control module in communication with the first AGP bus control module, communicable with an AGP device via a second AGP bus. The identifying codes of the first and second AGP bus control modules are set to show no AGP device function in order to allow the AGP device to communicate with the north bridge chip via the expansion adapter. The expansion adapter further includes a PCI bus control module in communication with the PCI device and the first AGP bus control module for controlling data transmission between the first AGP bus control module and the PCI device.

    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.

    摘要: The present invention provides a method of hot switching data transfer rate on the bus to hot switch the data transfer rate of the bus between the control chips without the process of RESET. When the bus between the control chips demands a large amount of data transfer, the bus is hot switched to a higher data transfer rate to fulfill the data transfer requirement. Contrarily, when the bus between the control chips demands less amount of data transfer, the bus is hot switched to a lower data transfer rate to save power consumption.

    摘要: A two-way cache system for interfacing with a peripheral device and a method of operating a two-way cache system for carrying out data transmission between a peripheral device and a memory unit. The cache system has a two-way first-in first-out buffer region and a two-way cache controller. The two-way first-in first-out buffer region further has a first cache data region and a second cache data region. The first cache data region and the second cache data region are capable of holding a batch of first cache data and a batch of second cache data. The two-way cache controller receives a read request from the peripheral device. According to the read request, the requested data and data that ensues or comes after the requested data are retained by the two-way first-in first-out buffer (FIFO) region. If the peripheral device continues to request more data by maintaining a FRAME signal line in an enabled state, the first cache data region and the second cache data region are alternately used to read in subsequent data. A check may be made to see if requested data stored inside the two-way cache buffer region is coherent or consistent with data stored inside the memory unit.

    摘要: A bus data interface, structure and method for transmitting the data of a PCI bus is disclosed. The bus data interface comprises a high-bit transmitting buffer, a low-bit transmitting buffer, a multiplexer, a strobe generator, and a data distributor. The strobe generator utilizes the bus request signal and bus grant signal to transmit a data strobe signal in response to the PCI clock. According to the rising edge and falling edge of the data strobe signal, the data distributor retrieves data according to the data strobe signal. Further, the invention is compatible with the original PCI bus and allows the PCI bus to transmit data with a dual speed.
