PORT CONFIGURATION METHOD AND DEVICE FOR HIGH-SPEED PERIPHERAL COMPONENT INTERCONNECT EXPRESS

摘要

Disclosed are a port configuration method and device for a high-speed peripheral component interconnect express. The method comprises: reading a pull-up and/or pull-down level value of a PCIE auxiliary signal line on a PCIE master device, identifying the type of a PCIE board card in accordance with the read pull-up and/or pull-down level value, the PCIE board card being connected to the PCIE auxiliary signal line, and performing pull-up and/or pull-down processing on the PCIE auxiliary signal line by a pull-up and/or pull-down device (101); and configuring the PCIE bus line on the PCIE master device to be a PCIE port matching with the type of the PCIE board card (102). The solution reduces the overhead for identifying the type of the PCIE board card while achieving the purpose of configuring the port type of the PCIE master device in accordance with the PCIE board card type.
