    摘要： To provide an arithmetic logic device that achieves arithmetic processing in a relatively short time on a relatively small circuit scale. [Solving Means] There is provided the logic operation device including a memory device 12 configured to store a lookup table and receive the input of a bit string N bits long, N being an integer of at least 2, the input bit string representing the address in the lookup table at which is stored multiple-bit data of which a part includes a bit representative of the result of a logical operation performed between the bits included in the input bit string. The memory device 12 is accessed so as to output the bits included in the data stored at the address represented by the received bit string.

    [Solving Means]
    There is provided the logic operation device including a memory device 12 configured to store a lookup table and receive the input of a bit string N bits long, N being an integer of at least 2, the input bit string representing the address in the lookup table at which is stored multiple-bit data of which a part includes a bit representative of the result of a logical operation performed between the bits included in the input bit string. The memory device 12 is accessed so as to output the bits included in the data stored at the address represented by the received bit string.

    摘要翻译： 提供一种在相对较小的电路规模上在相当短的时间内实现算术处理的算术逻辑器件。 [解决方案]提供了包括存储器装置12的存储装置12，其被配置为存储查找表并接收N位长的位串的输入，N是至少为2的整数，输入的位串表示地址 在查找表中存储多位数据，其中的一部分包括表示在包括在输入位串中的位之间执行的逻辑运算的结果的位。 访问存储器件12以输出包含在存储在由接收的位串表示的地址处的数据中的位。
