Peripheral high-speed interconnection interface PCIe board card, cable, verification system and computer

Abstract

The invention provides a peripheral high-speed interconnection interface PCIe board card. The peripheral high-speed interconnection interface PCIe board card comprises a substrate; one or more PCIe slots, wherein each PCIe slot is provided with an auxiliary signal pin and a plurality of data path pins; the more than one data path connector group is arranged in one-to-one correspondence with the more than one PCIe slot, each data path connector group is provided with more than one data path connector, and the data path connectors are in one-to-one correspondence communication connection with at least part of data path pins in the corresponding PCIe slot; and the auxiliary signal connector is in communication connection with more than one auxiliary signal pin of the PCIe slot. According to the peripheral high-speed interconnection interface PCIe board card provided by the invention, any number of data path pins in the to-be-expanded PCIe slot can be introduced into the corresponding data path connectors, so that the PCIe port can be used or verified freely and flexibly.

Description

technical field [0001] The invention relates to the technical field of PCIe communication, in particular to a peripheral high-speed interconnect interface PCIe board, cable, verification system and computer. Background technique [0002] Currently, the maximum number of data path pins supported by a PCIe port is PCIe X16. In addition, there are PCIe ports with data path pins such as PCIeX8, PCIe X4, PCIe X2, and PCIe X1. In the CPU chip design process of the central processing unit, a PCIe X16 port is generally designed as multiple ports supporting various data path pins of X8, X4, X2 and X1, that is, one X16 can be configured as one X16 port, or Can be configured as 2 X8 ports, or 8 X2 ports, or 16 X1 ports, or a combination of multiple ports with different channel pin count widths, such as 1 X8 port, 1 X4 port and 2 X2 ports The combination. Based on this design idea, it is necessary to expand a PCIe X16 slot into multiple PCIe slots for use or verification no matter in ...
