Data compression using dummy codes










Image Number 5 for United States Patent #7256715.

Received data is compressed according to an algorithm, which is a modification of the conventional LZW algorithm. A limited number of hash values are formed, and a code memory is searched at locations corresponding to the hash values. If all of the locations contains a valid code, but none of them contains a valid code corresponding to a potential new code, a dummy code is created, and a counter, which indicates the number of codes created, is incremented. The algorithm can be implemented in parallel in hardware.
