Evaluating alternative encoding solutions during data compression

Evaluating alternative encoding solutions during data compression

Method and apparatus for compressing data. In accordance with various embodiments, an input string of data bits is received and arranged into fixed-sized chunks. Multiple successive chunks of the input string are compared to previously received chunks of the input string during a single clock cycle....

description Method and apparatus for compressing data. In accordance with various embodiments, an input string of data bits is received and arranged into fixed-sized chunks. Multiple successive chunks of the input string are compared to previously received chunks of the input string during a single clock cycle. At least two alternative encoding solutions are identified based on matches obtained during said comparison. The input string is compressed to form a compressed output string using a selected one of the at least two alternative encoding solutions that achieves a fewer number of bits in said output string.
