Problems solved by technology

However, there is a limitation in this structure in practical applications. When the Qsgmii peer interface fails, for example, the port sequence of the peer Qsgmii is out of sequence, or there are multiple ports containing k28.1 codes, the reception of the local Qsgmii The side cannot recognize the error of the Qsgmii interface of the opposite end, and will still receive the data of the Qsgmii interface of the opposite end

Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0044] The data processing method provided by the embodiment of the present invention improves the existing receiving side Qsgmii receiving side, and improves the shifting module so that the shifting module can move 1 bit or 10 bits at a time, and at ports 1, 2, and 3 A k28.1 code detection module is added to the channel, so that the channels of ports 1, 2, and 3 on the receiving side can recognize the k28.1 code, and feed back and output a code_error signal to the mobile module of the previous stage. When the 1, 2, and 3 ports of the Qsgmii receiving side of the local end receive the k28.1 code, they will consider the code stream to be wrong, so that the shift module will move 10 bits of data at a time, and re-synchronize the sync process to avoid receiving wrong data from the...

Abstract

The embodiment of the invention discloses a data processing method and device. According to an error type, a shifting operation type of first data is determined; according to the shifting operation type, a shifting operation is carried on the first data to obtain second data; and the second data is distributed to a plurality of ports.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data processing method and device. Background technique [0002] 4 Serial Gigabit Media Independent Interface (Qsgmii, Quard Serial Gigabit Media Independent Interface) uses fewer pins to interconnect the physical layer phy with the port rate of 4 channels at 10 / 100 / 1000 and the media access control layer mac. The Qsgmii interface is a 5G serial high-speed serdes interface. [0003] Prior art Qsgmii interface, such as figure 1 As shown, the receiving end completes synchronization by identifying the k28.1 code on the serial code stream. After identifying the k28.1 code on the serial code stream, determine the position of port 0, followed by ports 1, 2, and 3. Location. However, there is a limitation in this structure in practical applications. When the Qsgmii peer interface fails, for example, the port sequence of the peer Qsgmii is out of sequence, or there ar...
