Abstract
An accelerated compression method and apparatus are provided. The accelerated compression apparatus includes a look-ahead buffer, a string matching processing pipeline and a control circuit. The string to be compressed extracted from the data register is stored to the look-ahead buffer. P instances are issued in parallel from the look-ahead buffer in each issue cycle. When P substrings corresponding to the instances are identical to each other, one of the P instances is sent to the string matching processing pipeline for a matching operation by the control circuit, and the remaining instances of the P instances are prevent from being sent to the string matching processing pipeline.
