阅读说明：本技术 一种数据传输方法和装置 (Data transmission method and device ) 是由 何向 于 2019-05-15 设计创作，主要内容包括：本申请实施例公开了一种数据传输方法,包括：第一芯片接收第二芯片器件发送的第一数据流；所述第一数据流为采用第一前向纠错FEC码型编码的数据流；所述第一芯片器件对所述第一数据流再进行至少一次编码,得到第二数据流；其中,所述第二数据流为至少采用所述第一FEC码型和第二FEC码型编码的级联FEC码流。可见,FEC码型的转换过程得以简化,FEC码型转换时所要耗费的时延及设备功耗都得以减小,从而数据传输效率得以提高。此外,本申请实施例还公开了一种数据传输装置。(The embodiment of the application discloses a data transmission method, which comprises the following steps: the first chip receives a first data stream sent by a second chip device; the first data stream is a data stream coded by a first Forward Error Correction (FEC) code pattern; the first chip device encodes the first data stream at least once again to obtain a second data stream; and the second data stream is a cascade FEC code stream coded by at least adopting the first FEC code pattern and the second FEC code pattern. Therefore, the conversion process of the FEC code pattern is simplified, the time delay consumed during the conversion of the FEC code pattern and the equipment power consumption are reduced, and the data transmission efficiency is improved. In addition, the embodiment of the application also discloses a data transmission device.)
