摘要： The present invention includes two variations of an apparatus which generate a version of the IORC* bus signal that is supplied to the read strobe input of a floppy disk controller that is asserted at the appropriate time during verify cycles between the floppy disk controller and a DMA controller. These designs allow an 82077 floppy disk controller to operate properly in FIFO mode when it is being used with software that does not require generation of this signal. The designs include use of a PAL and certain bus signal inputs to generate a signal which is asserted at the appropriate times during verify transfers. This signal is combined with the regular IORC* bus signal to produce the signal that is provided to the read strobe input of the floppy disk controller.

摘要： A first input signal is received at a data input of first synchronizer, the first data input to be synchronized to a clock. A second input signal is received at a data input of second synchronizer, the second signal to be synchronized to the clock. Transitions are prevented from being received at a clock input of the first synchronizer and from being received at a the clock input of the second synchronizer in response to the first input signal having the same logic value as a first output signal at an output of the first synchronizer and the second input signal having the same logic value as a second output signal at an output of the second synchronizer.

摘要： A technique is disclosed for facilitating data processing in a computer system. The technique utilizes logic to implement a dual mode design for PCI/PCI-X computer systems that enables optimal efficiency in regardless of which mode the system is operating in. The technique involves the implementation of two sets of transmitting and receiving elements, one tuned to PCI protocol timing and the other to PCI-X protocol. Therefore, allowing the system to process both PCI and PCI-X transactions without adversely affecting the other functional mode. The technique also enables an operator to adjust the clock timing separately for each protocol without having a detrimental affect on the other operating protocol.

摘要： A method for processing a PCI-X transaction in a bridge is disclosed, wherein data is retrieved from a memory device and is stored in a bridge then delivered to a requesting device. The method may comprise the acts of allocating a buffer in the bridge for the PCI-X transaction, retrieving data from a memory device, wherein the data comprises a plurality of cachelines, storing the plurality of cachelines in the buffer, wherein the plurality of cachelines are tracked and marked for delivery as the plurality of cachelines are received in the buffer, and delivering the plurality of cachelines to the requesting device in address order, the plurality of cachelines transmitted to the requesting device when one of the plurality of cachelines in the buffer aligns to an ending address of an allowable disconnect boundary (ADB) and the remaining cachelines are in address order.
