    • PURPOSE: A Reed-Solomon decoder and a decoding method of the decoder are provided which uses a minimum number of multipliers without regard to the number of correctable errors when a polynomial is calculated using the modified Euclid algorithm. CONSTITUTION: A polynomial calculator(204) calculates a syndrome value from received data to constructs a syndrome polynomial. A generator(202) generates a root for the initial error locator polynomial from error information of the input data, and generates a control signal indicating a new root for the initial error locator polynomial whenever new error information is input. The first polynomial developing part(206) develops the initial error locator polynomial using the root and control signal for the initial error locator polynomial to apply the developed initial error locator polynomial to a processor. The second polynomial developing part(208) develops the modified syndrome polynomial using the root and control signal for the syndrome value and the initial error locator polynomial to apply the developed polynomial to the processor.
