摘要: The present invention consists of a method managing an electronic microcontroller system, the system comprising two processors (CPU1, CPU2) with first processor (CPU1) intended for execution nonsecure application (Appli1) exhibiting nonguaranteed level functional security and integrity, second (CPU2) dedicated to secure (Appli2) implementing code data, involving guaranteed said being able implement function; means access (CT) shared memory space (MEM). According invention, comprises unit (MMU1) configured in such way that it implements write control, so as manage (MEM), is not modifiable when its function.
