Zusammenfassung:PROBLEM TO BE SOLVED: To provide address processing in two or more address spaces with a different length of address field. SOLUTION: One method as an example for allocating addresses IO, MEM0, MEM1, SPEC in the two or more address spaces with the different length of address field defines an address type, allocates a value in the first bit in a higher order of the address field to identify the first address type, allocates the second bit in a lower order of the address field to identify the address of the first address type, and inserts an additional bit with a different number between the first bit and the second bit in the two or more address spaces.
