Zusammenfassung:A method for providing improved data compression efficiency to a data compressor unit is disclosed. Before sending the uncompressed data stream to the data compressor unit, an incoming data byte from the uncompressed data stream is first compared with a preceding data byte from the uncompressed data stream. A first counter value is incremented in response to a match between the incoming data byte and the preceding data byte. A second counter value is then incremented in response to subsequent matches between an incoming data byte and its preceding data byte after the first counter value has reached a preset value. The second counter value is finally sent to the data compressor unit at the completion of a run of the incoming data byte in substitution of a portion of the run. such that the data compressor unit can quickly resume its optimal compression ratio after an occurrence of the run within the uncompressed data stream.
