Abstract:
1. A method comprising: accessing a sample data set including a plurality of fixed-length sample bit fields; determining numbers of remaining bits in each of the plurality of fixed-length sample bit fields, a number of remaining bits indicating a number of bits in a fixed-length sample bit field after removing leading zeros from the sample bit field; generating a plurality of prefix code mappings, each prefix code mapping associating a prefix code with each number of remaining bits after removing leading zeros from the sample bit fields; selecting a prefix code mapping; receiving a fixed-length bit field; determining a most significant bit of the fixed-length bit field; removing zeros preceding the most significant bit from the fixed-length bit field; determining a number of remaining bits in the fixed-length bit field after removing the zeros; identifying a prefix code associated with the number of remaining bits in the fixed-length bit field based on the selected prefix code mapping; appending the prefix code to the remaining bits in the fixed-length bit field; appending leading zeros before the prefix code to generate a bit field having a length that is an integer multiple of a byte of data; and storing the generated bit field having the length that is the integer multiple of the byte of data.
