A novel and useful system and method of fast history compression in a pipelined architecture with both speculation and low-penalty misprediction recovery. The method of the present invention speculates that a current input byte does not continue an earlier string, but either starts a new string or represents a literal (no match). As previous bytes are checked if they start a string, the method of the present invention detects if speculation for the current byte is correct. If speculation is not correct, then various methods of recovery are employed, depending on the repeating string length. |
