Abstract

The invention relates to a double-channel redundant data exchange method and system based on an Aurora protocol. The system comprises a first Aurora protocol module Aurora_0, a second Aurora protocol module Aurora_1, a receiving side module Rx_top, a redundancy elimination module Rd_arbiter, a data caching module dma_ctrl, a data arrangement sending module Tx_engine, a data analysis receiving module Rx_engine, a data shunt sending module Wr_arbiter and a sending side module Tx_top. Two independent working interfaces, namely the first Aurora protocol module Aurora0 and the second Aurora protocol module Aurora1, are used, the accuracy of data in a link is improved, one path of external data which is verified preferentially is input into the redundancy elimination module Rd_arbiter, data caching is achieved, the data throughput can be controlled, data loss cannot be caused, and the two paths of redundant data in the cache are judged according to the judgment condition, so that redundancy removal operation is realized, and the transmission mode improves the data stability at a high rate.

Description

technical field [0001] The invention relates to the technical field of high-speed communication equipment, in particular to a dual-channel redundant data exchange method and system based on the Aurora protocol. Background technique [0002] With the popularization of communication technologies such as 5G, the demand for real-time data processing, transmission speed, and high bandwidth of communication equipment is gradually increasing. The low-speed transmission bus traditionally used in embedded systems has the advantages of strong stability and simple operation. However, due to the limitation of transmission bandwidth, it is easy to become a bottleneck in data transmission; traditional high-speed protocols used between devices have the advantages of high bandwidth and low delay, but due to poor interface versatility, complex transmission protocols, and gradually increasing data transmission channels, Increased the difficulty and cost of development. [0003] In order to c...
