A method of operating a data compression circuit includes receiving and storing a plurality of data blocks until a cache is full and writing the data blocks that have been stored in the cache to a buffer memory when the cache is full. The method also includes performing forced literal/literal encoding on each of the data blocks regardless of repetitiveness of each data block when the cache is full.

Method of operating data compression circuit and devices to perform the same

A data compression method includes receiving an input data stream including a previous data block and a current data block, and executing a first comparison of a part of the previous data block with part of a previous reference data block, and a second comparison of the current data block with a current reference data block, where the first and second comparisons are executed in parallel. The method further includes selectively, based on results of the first and second comparisons, outputting the current data block or compressing an extended data block, where the extended data block includes the part of the previous data block and the current data block.
