Method and apparatus for data processing

A computer program, designed for carrying out a method for processing an operating sequence of instructions of a program in a processor,

• wherein each instruction is represented by an assigned instruction code which comprises one execution step to be processed by the processor or a plurality of execution steps to be processed successively by the processor, comprising:
• determining an actual signature value assigned to a current execution step of the execution steps of the instruction code representing the instruction of the operating sequence:
• determining, in a manner dependent on an address value, a desired signature value assigned to the current execution step;
• and
• if the actual signature value does not correspond to the desired signature value, omitting at least one execution step directly available for execution and an execution step indirectly available for execution.

A method for providing an instruction code representing one or a plurality of instructions of an operating sequence of a computer program which is provided for being carried out in a processor, wherein the instruction code representing a respective instruction comprises one execution step to be executed by the processor or a plurality of execution steps to be executed successively by the processor, comprising:

• translating a program text representing the operating sequence into the instruction code;
• defining an inception execution step assigned to the operating sequence in the instruction code;
• and
• allocating a signature change value to the inception execution step.

A compiler product,

• designed for creating a computer program,
• by compiling a program text representing the operating sequence in order to provide the instruction code representing the operating sequence,
• and furthermore designed to define an inception execution step assigned to the operating sequence and to allocate a signature change value to the inception execution step, said computer program being designed for carrying out a method for processing an operating sequence of instructions of a program in a processor,
• wherein each instruction is represented by an assigned instruction code which comprises one execution step to be processed by the processor or a plurality of execution steps to be processed successively by the processor, comprising:
• determining an actual signature value assigned to a current execution step of the execution steps of the instruction code representing the instruction of the operating sequence;
• determining, in a manner dependent on an address value, a desired signature value assigned to the current execution step;
• and
• if the actual signature value does not correspond to the desired signature value, omitting at least one execution step directly available for execution and an execution step indirectly available for execution.
