Problems solved by technology

[0003] However, when the SerDes is applied at a high rate, the system needs to perform link training such as pre-emphasis and receive equalization, but these link trainings are often relatively slow, and usually the order of magnitude of time consumed by each SerDes training is seconds, thus Affects the initialization time of the entire system

Abstract

Embodiments of the present invention provide a device and system with a multi-channel binding interface and a quick initialization method thereof. The device with multi-channel binding interface of the present invention includes: a port, a control state machine and a processor; the port includes a plurality of interfaces of different types bound; the processor includes a training processing module for training a plurality of interfaces of different types The control state machine is used to trigger the training processing module to train the first interface among multiple different types of interfaces, so as to provide the device with an available link to other devices via the first interface, and the processor passes the first interface on the available link. When an interface further initializes the device, the training processing module is triggered to train at least one second interface among multiple interfaces of different types; the bandwidth of the first interface is sufficient for further initializing the device. The embodiment of the present invention can realize fast initialization of a system with a multi-channel binding interface.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a device and system with a multi-channel binding interface and a quick initialization method thereof. Background technique [0002] With the rapid development of data broadband networks, it is necessary to continuously increase the communication bandwidth between systems. The current trend is that communication protocols, such as Ethernet, bus and interface standards (Peripheral Component Interface Express, referred to as: PCIE), etc., use multi-lane (lane) binding Serializer / Deserializer (Serializer / Deserializer, referred to as: SerDes) ) technology as a physical layer interface, that is, a multi-channel bonding interface to meet the increase in bandwidth demand. Each type of interface may use a different communication protocol or have a different maximum data transfer rate. [0003] However, when the SerDes is applied at a high rate, the system needs...
