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 clock generating apparatus and method for generating clock signals of different frequency. The clock generating apparatus and method receives and divides a main clock signal to obtain a reference clock signal. Then, the reference clock signal and the first feedback clock signal are phase-locked to obtain the first clock signal. Moreover, the reference clock signal and the second feedback clock signal are phase-locked to obtain the second clock signal. The reset signal and the first clock signal are received by a divider. The divider then outputs the first feedback clock signal. Another divider receives the reset signal and the second clock signal and then outputs the second feedback clock signal.

摘要： A signal delay device having an internal delay lock loop for calibrating the delay interval. The signal delay device receives an input signal and then outputs the signal after a pre-defined delay period. The input signal varies according to a reference clock signal, and the required delay period is a quarter cycle of the clock signal. The delay device includes a multiplexer, an inverter, a phase detector, a counter and a delay element. During calibration, the phase detector, the counter and the delay element form a delay lock loop that can set up the delay time automatically.

摘要： An apparatus and method capable of programmably delaying a clock of a memory. The apparatus and method utilize the BIOS, external electric switches or other logic devices to selectively delay the clock of the DRAM and/or the internal clock of the north bridge, by which the DRAM has enough setup time at the rising edge of work clock to correctly read out the command word. The north bridge can then correctly receive data from the DRAM module and transfer the data to the CPU or AGP. Therefore, the memory can function normally even if the memory is operated at high speed or with heavy loading.

摘要： The present invention is directed to a stream context cache system, which primarily includes a cache and a mapping table. The cache stores plural stream contexts, and the mapping table stores associated stream context addresses in a system memory. Consequently, a host may, according to the content of the mapping table, directly retrieve the stream context that is pre-fetched and stored in the cache, rather than read the stream context from the system memory.
