Abstract: In embodiments of the present invention, a PCI bus to PCE Express protocol conversion module includes a process implemented by control logic to convert streaming PCI information to PCI Express packets. In one embodiment, an agent may transfer PCI data and associated byte enables to a first queue, which may temporarily store the PCI data and associated byte enables in a quad word format. A decoder may determine whether the PCI byte enables are combinable, contiguous, and/or active, and, using state machines, transfer a quantity of the PCI data and associated byte enables from the first queue to a second larger queue. The state machines may break the PCI stream to arrive at the quantity of PCI data being transferred. The second queue may have at least one location to temporarily store the quantity of data and byte enables in at least one packet having a PCI express format.
