Processor for monitoring control flow of program during processing of program, has instruction set, where branch at address leads to error status of processor, and no appropriate start-up instruction is available at address

摘要

The processor has an instruction set containing branch instructions and start-up instructions. The start-up instructions are appropriately assigned to the branch instructions in the instruction set and addresses are allowed in error-free programs as target of the branch instructions, where the appropriate start-up instructions are available at the addresses. A branch at one of the addresses leads to an error status of the processor, where no appropriate start-up instruction is available at the address.
