A PCI(Peripheral Component Interconnect) express packet detector including a descrambling function is provided to classify each hierarchical packet on a PCI express protocol, and to distribute the packets on a hierarchical basis, thereby reducing unnecessary use of a buffer. A physical layer packet detector(310) detects physical layer packets from PCI express packets received in parallel in 16 bits through a physical layer serializer/deserializer. A descrambling unit(340) descrambles the PCI express packets. A data link layer packet detector(320) detects data link layer packets from the packets outputted from the descrambling unit(340). A transaction layer packet detector(330) detects transaction layer packets from the packets outputted from the descrambling unit(340). |
