Abstract
A black box recorder for an autonomous vehicle includes an interface configured to receive data from an engine control unit (ECU) device. The data includes first data and second data. The black box recorder further includes an error correction code (ECC) engine configured to determine a first parity size associated with the first data based on a characteristic of the first data and a second parity size associated with the second data based on a characteristic of the second data. The first parity size is different than the second parity size. The ECC engine is further configured to generate a convolutional low-density parity-check (CLDPC) codeword that includes the first data, the second data, first redundancy data associated with the first data, and second redundancy data associated with the second data. The first redundancy data has the first parity size, and the second redundancy data has the second parity size.
