Forward error correction code fec design method and related device

A data processing apparatus, comprising:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
• determine a quantity of transmission lanes for transmitting data;
• determine a plurality of forward error correction (FEC) working areas based on the quantity of transmission lanes, wherein a quantity of the plurality of FEC working areas is the same as the quantity of transmission lanes, and the plurality of FEC working areas are for performing check and error correction on the data;
• evenly allocate data on a transmission lane of the transmission lanes to each of the plurality of FEC working areas;
• and
• process, by using the plurality of FEC working areas, data received by each of the plurality of FEC working areas.

A computer-readable storage medium storing programming instructions for execution by at least one processor, that when executed by the at least one processor, cause a computer to perform operations comprising:

• determining a quantity of transmission lanes for transmitting data;
• determining a plurality of FEC working areas based on the quantity of transmission lanes, wherein a quantity of the plurality of FEC working areas is the same as the quantity of transmission lanes, and the plurality of FEC working areas are for performing check and error correction on the data;
• evenly allocating data on a transmission lane of the transmission lanes to each of the plurality of FEC working areas;
• and
• processing, by using the plurality of FEC working areas, data received by each of the plurality of FEC working areas.
