Variable length cldpc encoder and method of operation in an autonomous vehicle

An apparatus comprising:

• an interface configured to receive data from a device, the data including first data and second data;
• and
• an error correction code (ECC) engine configured to determine a first parity size associated with the first data and a second parity size associated with the second data, the first parity size different than the second parity size, and to generate a convolutional low-density parity-check (CLDPC) codeword that includes the first data, the second data, first redundancy data, and second redundancy data, wherein the first redundancy data is associated with the first data and has the first parity size, and wherein the second redundancy data is associated with the second data and has the second parity size.

An apparatus comprising:

• means for receiving data from a device, the data including first data and second data;
• and
• means for determining a first parity size associated with the first data, for determining a second parity size that is associated with the second data and that is different than the first parity size, and for generating a convolutional low-density parity-check (CLDPC) codeword that includes the first data, the second data, first redundancy data, and second redundancy data, wherein the first redundancy data is associated with the first data and has the first parity size, and wherein the second redundancy data is associated with the second data and has the second parity size.
