ABSTRACT:
An address converting method for use in a data processor with a virtual memory. The method includes a step for generating effective addresses by the use of address registers, and a step for deciding whether or not an operating mode which is defined for each process is in an activated state. The method also includes a step responsive to a positive determination at the previous step for determining whether or not an address register having a specific reference number was used in the generation of the effective addresses, and a step responsive to a negative determination at the foregoing step for converting an effective address into a physical address. Furthermore, the method includes a step which is responsive to a positive decision of the step determining register use for treating the effective address generated as a physical address, and a step for accessing a memory by the physical address resulting from the conversion step or that from the physical address step.
