<p>The subject of the present invention is an electronic microcontroller system comprising: · several processors (CPU1, CPU2, CPU3); · at least one interface for exchange with at least one peripheral (LCD, USB, PCIe, MAC), said peripheral being user master of said electronic microcontroller system; · means of access (CT) to a shared memory space; · an interconnection matrix (M) for interconnecting said exchange interface, said processors (CPU1, CPU2, CPU3) and said means of access (CT) to a shared memory space. The electronic microcontroller system moreover comprises means for managing applications involving a guaranteed level of security and integrity and of applications exhibiting a nonguaranteed level of security and integrity. According to the invention, said exchange interface cooperates with a secure isolation cell of the memory (SMIC) situated between said user master peripheral (LCD, USB, PCIe, MAC) and the interconnection matrix (M).</p> |
