    • An apparatus includes a unit dividing a region into blocks having a predetermined bit length and generating addition data having the predetermined bit length corresponding to coordinate data, a unit storing storage data having the predetermined bit length, a unit generating composite data having a bit length twice the length of the predetermined bit length by connecting the addition data to the storage data, and storing the composite data, and a unit repeating an operation of designating the bit length of the composite data as the predetermined bit length, instructing to generate the addition data, and instructing to generate and store the composite data. The number of different bits between a bit string of a location corresponding to the input coordinate data and a bit string of a reference location tends to increase as a distance between the location corresponding to the coordinate data and the reference location increases.
    • 一种装置包括将区域划分成具有预定位长度的块并产生具有与坐标数据相对应的预定位长度的附加数据的单元,存储具有预定位长度的存储数据的单元,具有位长度两倍的单位生成单元 通过将加法数据连接到存储数据,并存储合成数据的预定位长度的长度,以及重复指定复合数据的位长度的操作的单元作为预定位长度,指示生成相加数据 并指示生成和存储复合数据。 对应于输入坐标数据的位置的位串与参考位置的位串之间的不同位的数目趋向于随着对应于坐标数据的位置和参考位置之间的距离增加而增加。

    • A data partitioning apparatus receives stream data and stores with previous-and-subsequent information that specifies data previous and subsequent to the data. Then, for groups, each of which contains the data that are stored and that are partitioned into the number of the groups, the data partitioning apparatus stores top information specifying data located at the top in a corresponding group and end information specifying data located at the end in the corresponding group. Then, when new data is stored, the data partitioning apparatus specifies data previous and subsequent to the new data and stores the new data by associating it with the previous-and-subsequent information that specifies the data previous and subsequent to the new data. Then, when data is inserted, the data partitioning apparatus updates information for each group such that the difference between the number of data belonging to each group is equal to or less than one.
