Abstract
A method and a circuit of automatic control of the execution of a program by a microprocessor, including: assigning a digital decrement or increment to at least one function of the program; assigning a digital increment, respectively decrement, to at least one section considered as critical as to the program execution and called by the function; setting a counter to a first value; decrementing, respectively incrementing, the counter once per function before a call to a critical section; incrementing, respectively decrementing, the counter on each correct execution of a section; and comparing the current value of the counter with a predetermined critical threshold.
