Providing efficient lossless compression for small data blocks in processor-based systems is provided. In one aspect, a method comprises receiving a plurality of input words. Each mask of a plurality of masks is applied to each unassigned input word to generate a corresponding plurality of patterns. For each mask, if a most frequently occurring pattern exists among the plurality of patterns, the most frequently occurring pattern and an uncompressed data portion of each unassigned input word are stored in association with a prefix associated with the mask. The prefix is also assigned to each unassigned input word corresponding to the most frequently occurring pattern. A compressed output block is generated, comprising prefixes assigned to the plurality of input words, the most frequently occurring patterns associated with the assigned prefixes, and uncompressed data portions corresponding to one or more input words of the plurality of input words.
