ABSTRACT:
Embodiments are provided in which a method is described for a processor to perform a task of accessing a PCI-X device via a PCI-X bridge, the PCI-X bridge including a processing circuit. The processor builds M read/write control blocks (RWCBs), M being a positive integer. Then, the processor signals the processing circuit and switches to another task. In response, the processing circuit fetches and processes the M RWCBs, one RWCB at a time, to access the PCI-X device. After processing the M RWCBs, the processing circuit interrupts the processor. In response, the processor obtains the result of the processing of the M RWCBs.
