EFFICIENT CHIEN SEARCH METHOD IN REED-SOLOMON DECODING, AND MACHINE-READABLE RECORDING MEDIUM INCLUDING INSTRUCTIONS FOR EXECUTING THE METHOD |
摘要 |
An efficient Chien search method in Reed-Solomon decoding is adapted to be implemented in a processor having a parallel processing instruction set. The method includes the following steps: (a) calculating an error evaluation value; (b) subjecting the error evaluation value to mapping processing so as to find an index adjusting value; (c) storing a symbol index into an error location memory corresponding to a location index; (d) updating the location index according to the index adjusting value; (e) updating the symbol index; and (f) repeating steps (a) to (e) a particular number of times. The method primarily aims to reduce program flow branching so as to enhance the computation efficiency of the Chien search process.
