Data Compression Utilizing Variable and Limited Length Codes |
摘要 |
According to one embodiment, method for decoding encoded data comprises a hardware module including circuitry to process a data stream. The data stream includes one or more encoded symbols each including a code assigned to a corresponding symbol. A set of least frequently occurring symbols are assigned a common code to encode those symbols within the data stream. Data blocks are generated each containing a data stream portion. One or more encoded symbols within each data block are identified by comparing data block portions to maximum code values for corresponding code lengths to determine a code length for each data block portion. A starting location for the identified encoded symbols within each data block is determined based on the determined code lengths.
