ADDRESS CONVERSION SYSTEM

PURPOSE:To develop an information processing system superior in productivity and high in reliability by detecting access to data by a logic pointer, and converting a code to an instruction code to make access to the data by converting logic address to a physical address by a compiler. CONSTITUTION:The compiler recognizes a specific variable as a pointer variable in which the logic address is attached, and generates an object code to call an address conversion mechanism 3 according to a decided connecting specification for the reference of the data indicated by the logic address. And the object code to make access to the data is generated by the physical address 4 that is a conversion result. Normally, a value in which one time of conversion is applied can be used as it is for a short period. Therefore, the compiler can manage the effective period of a converted physical address by a context in a program targeted to be compiled. In such a way, it is possible to eliminate a redundant address conversion code and to improve the execution efficiency of the program.
