METHOD FOR PARALLEL DATA INTEGRITY CHECKING OF PCI EXPRESS DEVICES

摘要

An apparatus and method for supporting PCI Express is disclosed. A physical layer has a PCI Express interface for receiving data from a PCI Express compatible communication medium. The data is in the form of a packet. A data link layer (502) is disclosed for verifying a CRC value (506) and a sequence number (508) received within the packet. A transaction layer (504) is disclosed for receiving the packet from the data link layer and for processing thereof. The transaction layer (504) processes (512) at least some of the packet data in parallel to the data link layer (502).
