Abstract:
In a PCI bus system for transferring write data in the form of write data bursts comprising a plurality of contiguous words, said PCI bus system having at least one PCI bus for coupling at least one PCI data source to said PCI bus system, and a PCI bus target coupled to said PCI bus for receiving and transferring said write data from said PCI data source, said PCI bus target queuing operation commands in a command queue, a method for limiting fracturing of said write data, comprising the steps of:sensing fracturing of said write data; upon said fracture sensing step sensing said fracturing by said PCI bus target, blocking access to said PCI bus; subsequent to said blocking step, monitoring completion of said queued operation commands of said PCI bus target; and upon said completion monitoring step indicating a predetermined number of said operation commands remain queued at said PCI bus target, allowing grants of access to said PCI bus by said at least one PCI data source.
