nibblepacked
Nibblepacked is a term used to describe data that is stored by packing two 4-bit nibble values into a single 8-bit byte, creating a dense representation for small integers or hexadecimal digits. It is not a formal standard, but a descriptive concept found in documentation and codebases that require space-efficient storage.
In a nibblepacked sequence, each byte comprises a high nibble and a low nibble. For example, the
Applications of nibblepacking include compact storage for BCD digits, streams of hexadecimal digits, sensor data in
Advantages of nibblepacked representations include reduced memory usage and potential improvements in cache efficiency. Limitations include
