Accelerated compression method and accelerated compression apparatus
An accelerated compression method and apparatus are provided. The accelerated compression apparatus includes a look-ahead memory, a string matching processing pipeline and a control circuit. According to an issue pointer, the control circuit issues sub-strings of a string to be compressed from the look-ahead memory to the string matching processing pipeline for a matching operation to obtain a matched length and a matched offset. The control circuit determines a new retiring position according to the matched length corresponding to a retire pointer. When the new retiring position exceeds an issuing position pointed by the issue pointer, the control circuit resets the string matching processing pipeline.
