Abstract

The invention relates to the technical field of equipment interconnection, and discloses quick interconnect equipment of peripheral components and a method thereof for matching with different communication terminals. The equipment comprises a detecting unit used for detecting an addressing space and a label bit wide supported by communicated opposite equipment, and a packing unit used for packinga communicated transmission layer protocol packet according to the addressing space and the label bit wide supported by the opposite equipment and detected by the detecting unit. Adaptive compatibility can be realized by aiming at a root complex or end equipment of the quick interconnection system of different peripheral components, and the system bandwidth performance can be optimized.

Description

technical field [0001] The invention relates to equipment interconnection technology, in particular to a peripheral device fast interconnection equipment and a method for matching with different communication terminals. Background technique [0002] The PCI-E (Peripheral Component Interconnect Express) system is a third-generation high-performance I / O bus that is based on the PCI-E protocol and is used to interconnect peripheral devices such as computing and communication platform applications. It can be applied to mobile The bus that interconnects all peripheral I / O devices such as equipment, desktop computers, workstations, servers, embedded computing and communication platforms. The PCI-E protocol supports two addressing formats of 32bit / 64bit space addressing. Different devices may support or be compatible with different addressing formats, or may only support one addressing format and are not compatible with other addressing formats. In this regard, the PCI-E protocol ...
