ABSTRACT:
Data processing apparatus having an execution unit, a flow controller having a program counter, and a program counter sensor, which is connected to a data bus and to the program counter. The program counter sensor has a logic unit that ascertains the address of an instruction which is to be executed next from data transferred via the data bus, and a comparator, which compares the ascertained address with a content of the program counter and triggers an alarm signal if there is any discrepancy.
