    • A modulo N calculating method for an M1*M2-bit binary integer, wherein N, M1 and M2 are integers, includes the steps of dividing the M1*M2-bit binary integer into M1 bits and performing AND operation on each M1 bits and a specific binary integer; and changing a value of an output register depending on the AND operation result and storing the value thereto. A modulo N calculating apparatus includes an input unit for receiving an M1*M2-bit binary integer, wherein N, M1 and M2 are integers; and an AND operation unit for performing AND operation on the M1*M2-bit binary integer and a specific binary integer. Furthermore, when the M1 and the N may be 4 and 3, respectively, the specific binary value may be 1010 or 0101.
    • 用于M1 * M2位二进制整数的模N计算方法,其中N,M1和M2是整数,包括以下步骤:将M1 * M2位二进制整数除以M1位,并对每个M1位和 具体的二进制整数; 并根据AND运算结果改变输出寄存器的值并存储该值。 模N计算装置包括用于接收M1 * M2位二进制整数的输入单元,其中N,M1和M2是整数; 以及AND运算单元,用于对M1 * M2位二进制整数和特定二进制整数进行AND运算。 此外,当M1和N分别为4和3时,特定的二进制值可以是1010或0101。
