  • Publication number: 20130326097
    Abstract: A semiconductor device capable of implementing system configurations corresponding to various PCIe topologies is provided. A RAM stores one or more configuration registers that define function information of a PCIe device. A Link control unit decodes a request received from a PCIe host and outputs a decoded result to a CPU. The CPU reads a corresponding configuration register from the RAM based on the decoded result received from the Link control unit, and generates a response to the request and causes the Link control unit to transmit the response. Thus, system configurations corresponding to various PCIe topologies can be implemented.
