Accelerated compression method and accelerated compression apparatus
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. A 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. When P substrings corresponding to the P instances issued in a first issue cycle are identical, the control circuit sends a first instance and a second instance of the P instances to the string matching processing pipeline for a matching operation and does not send the remaining instances of these P instances to the string matching processing pipeline. In consecutive issue cycles after the first issue cycle, the control circuit does not send any of the P instances to the string matching processing pipeline until the P substrings corresponding to the P instances are not identical.
