17 results about "Prefix code" patented technology

A prefix code is a type of code system distinguished by its possession of the "prefix property", which requires that there is no whole code word in the system that is a prefix (initial segment) of any other code word in the system. It is trivially true for fixed-length code, so only a point of consideration in variable-length code.

Fast prefix decoding

The present disclosure provides a method of decoding a prefix coded bitstream, the bitstream comprising prefix coded symbols, the symbols being of multiple different types. The method comprises: obtaining a first set of N bits of a prefix coded bitstream, wherein N > 2, wherein the first set of N bits contains at least part of a prefix code, wherein a prefix code is associated with a symbol, wherein a plurality of symbols form a set of symbols, the set of symbols comprising a leading symbol of a first type and at least one symbol of a second type, the second type different to the first type, wherein each symbol indicates a type of the following symbol, wherein a final symbol in the set of symbols indicates that the following symbol is of the first type; performing a first coding operation on the first set of N bits, wherein the first coding operation associates multiple prefix codes with multiple symbols. If the first coding operation obtains the leading symbol and final symbol in the set of symbols, then the method further comprises: obtaining a second set of N bits of the prefix coded stream, wherein the second set of N bits includes any undecoded bits of the first set of N bits. If the first coding operation does not obtain the final symbol in the set of symbols, then the method further comprises: iteratively performing a second coding operation until the final symbol in the set of symbols is obtained, wherein the second coding operation comprises obtaining a first set of P bits of the prefix coded stream, wherein 1 < P < N, wherein the first set of P bits includes any undecoded bits of the first N bits, wherein the second coding operation associates one prefix code in the first set of P bits with one symbol.

55 ABSTRACT Decoding of variable-length prefix code data of an image data stream A computer processing system for decoding an image data stream which includes 5 variable-length character-strings representing symbols which have been encoded in accordance with a variable-length prefix encoding scheme. The symbols represent image data. The computer processing system comprising processing logic configured to receive the image data stream and query an acceleration table on the computer processing system with a fixed number of characters of the received image10 data stream to identify an entry of the acceleration table. Each of a plurality of the entries of the acceleration table indicates a decoded symbol to be returned, and the acceleration table has multiple entries which indicate the same decoded symbol represented by a character-string having fewer than said fixed number of characters. The computer processing system is further configured to, if the identified entry 15 indicates a decoded symbol, output the decoded symbol indicated by the identified entry for use in forming an image.
