ABSTRACT:
An embodiment of the present inventions is a method for encoding/decoding data of variable length format and is used to omit unnecessary pieces of data for the purpose of improving processing performance, reducing the size of data on communication paths and efficiently using limited physical memory. As examples of such variable length encoding, BER compression and UTF-8 encoding of UNICODE text, etc., are cited. While the amount of data can be reduced through encoding, before the data is actually used, it is necessary to restore (decode) it to the original data, which requires a great deal of processing time. One aspect of the present invention is improving decoding by reducing the processing time required to decode the encoded data.
