摘要： An apparatus and method for updating a check node of a low-density parity check (LDPC) code in order to decode the LDPC code are provided. The method includes the operations of: (a) obtaining a first bit of a first minimum value among input values, the number of input values being equal to the number of degrees of the check node, by performing an AND operation on first bits of the input values, the first bits being most significant bits of the input values; (b) obtaining result values by switching and sequentially performing an XOR operation and an OR operation on the first bit of the first minimum value and each of the first bits of the input values; and (c) performing operations (a) and (b) on the result values set as input values and performing operations (a) and (b) a number of times corresponding to the number of bits of each input value, that is, repeating until last bits are set as input values, to thereby obtain the first minimum value, the last bits being least significant bits of the input values. Accordingly, the complexity of hardware is reduced, and super high-speed processing is possible.
