Abstract

PURPOSE:To perform transfer processing in string unit for a variable string data efficiently, by deleting the entry of a string in an associative storage means where at least a part is removed with a string newly stored. CONSTITUTION:If string data requested from an operation device 3 is not present in a variable length string buffer 4, the next address in a variable length string buffer 4 of string data transferred finally from a main storage device 1 is stored in a register 6. That is, the string data newly transferred to the variable length string buffer 4 is stored from the address of register 6, and the entry in the associative storage device 5 of the string data where a part of it is removed is removed by storing this data. Thus, the transfer processing in the string unit of the variable length string data can efficiently be realized.
