1. A method for operating a microprocessor, comprising: performing a binary translation by a conversion software implemented in the microprocessor, the binary translation including translating a source instruction in a binary manner into a target instruction, wherein the source instruction is encoded according to a first instruction-set architecture, and wherein the target instruction is encoded according to a second instruction-set architecture; replicating by the conversion software the target instruction translated into the second instruction-set architecture; in the replicated target instruction, replacing a memory area which is to be accessed in the course of executing the target instruction by a second memory area; and executing the target instruction and the replicated target instruction by the microprocessor.
