Abstract
(EN)
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).

La présente invention a pour objet un système de microcontrôleur électronique comportant : · plusieurs processeurs (CPU1, CPU2, CPU3); · au moins une interface d'échange avec au moins un périphérique (LCD, USB, PCIe, MAC), ledit périphérique étant maître utilisateur dudit système de microcontrôleur électronique; · des moyens d'accès (CT) à un espace mémoire partagé; · une matrice d'interconnexion (M) pour interconnecter ladite interface d'échange, lesdits processeurs (CPU1, CPU2, CPU3) et lesdits moyens d'accès (CT) à un espace mémoire partagé. Le système de microcontrôleur électronique comprend par ailleurs des moyens de gestion d'applications impliquant un niveau de sécurité et d'intégrité garanti et d'applications présentant un niveau de sécurité et d'intégrité non garanti. Selon l'invention, ladite interface d'échange coopère avec une cellule d'isolation sécurisée de la mémoire (SMIC) située entre ledit périphérique maître utilisateur (LCD, USB, PCIe, MAC) et la matrice d'interconnexion (M).
