Problems solved by technology

[0021] The disadvantage of the existing implementation technology is that although the de-skew of the data is realized, the sliding window and the window comparator used in the first method need to provide multiple buffer intervals and complex output control units, which require more resources, and the operation complex
Method 2. It uses RAM pointer control, which needs to realize the forward and backward movement of the pointer. At the same time, each channel needs independent pointer control, which causes waste of resources and reduces efficiency.

Abstract

The invention provides a multi-channel aligning de-bias method and a device. The method comprises the following steps: detecting data reaching a plurality of channels, and controlling the cache of all channel data according to detected tag blocks; and meanwhile, reading data from initial positions of all channel data of the cache. According to the invention, the complexity in multi-channel aligning de-bias design is reduced, the efficiency is improved and resources are saved.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and a device for aligning and de-offsetting multi-channel data of a high-speed data service medium independent layer. Background technique [0002] With the continuous development of communication technology, the carrying capacity of data services is getting stronger and stronger. From 10M / 100M services to 1G / 10G services and now to 40G / 100G services, the transmission bandwidth is getting higher and higher. In order to adapt to high-bandwidth transmission capabilities, data transmission has corresponding changes. Taking the Ethernet data service as an example, according to the medium-independent data interface of the data link layer and the physical layer in the OSI seven-layer model defined by OSI (Open System Interconnect) / IEC (International Electrotechnical Commission), 10M / 100M The Ethernet interface is MII (Medium Independence Interface, Media Independent Interfac...
