Abstract: A method can be used for verifying an execution of a compiled software program stored in a program memory of a processor and executed by the processor. A write operation includes assigning a destination address in a register of the processor and writing a datum at a location pointed to by the destination address contained in the register. A verification operation includes reassigning the same destination address in the same register, reading the datum contained at the location pointed to by the destination address contained in the register after the reassignment, and comparing the read datum and the written datum.
