Abstract: PROBLEM TO BE SOLVED: To optimize system memory addressing in an information processing. SOLUTION: This system 10 provides an addressing mode settable by users according to control information included in an input address. By using coding control information stored in an address replacement control resister (70 to 72) set by the plurality of users, specified bits of the input address are replaced, and it is judged whether what bit value must be used to selectively generate a corresponding replacement address. Since the pipeline of a processor need not be changed, various types of replacement addressing modes can be defined by the users, and executed by using either of a general processor and a dedicated processor.
