PURPOSE:To reduce the processing time, by reading in the continuity of the next string in advance in the incorporating process of string, when rearranging each unit data in ascending (or descending) order depending on the value of key in the data. CONSTITUTION:When the data which is the objective of classification and incorporation processing is inputted from the input unit 1, the read-in means 5 reads in it in the input buffer 31, the string forming means 6 shares the string to the output buffer 32 and writes in it to the greater memory unit 2. When the sharing is finished, n sets of strings are fetched to the input buffer 31 from the greater memory unit 2. The state of usage of the buffer 3 is memorized in the memory means 4, the string finishing the vacant buffer in the fastest way is assigned with the buffer instruction means 8, and the string required next is fetched in advance with the read-in means while incorporating the string with the incorporating means 9. |
