Except that the first prefix code is preconfigured, the generator generates a current prefix code by adding one to the adjacently previous prefix code and then shifting left by a certain number of bits. When the current prefix code is generated, the generator simultaneously judges whether the adjacently previous prefix code is identical to the current prefix code from the high bit, if yes, the error information is outputted; otherwise the prefix codes corresponding to the sorted code lengths are generated. The sequence regulator is used to receive the prefix codes corresponding to the sorted code lengths, and regulates the sequence of the prefix codes corresponding to the sorted code lengths according to the position correspondence relationship recorded by the sort indexer to obtain the prefix codes corresponding to the code lengths. The solution can report error in time. | 12-08-2011 |
