Renesas Electronics a annonc\u00e9 une plate-forme de virtualisation d’ECU automobile int\u00e9gr\u00e9e qui permet aux concepteurs d’int\u00e9grer plusieurs applications dans un seul ECU (unit\u00e9 de contr\u00f4le \u00e9lectronique) qui sont s\u00e9par\u00e9s les uns des autres en toute s\u00e9curit\u00e9 pour \u00e9viter les interf\u00e9rences. La solution permet aux clients d’adopter de nouvelles architectures \u00e9lectriques-\u00e9lectroniques (E\/E) en utilisant des ECU de zone bas\u00e9s sur MCU prenant en charge plusieurs ECU logiques dans le m\u00eame ECU physique. La migration vers la nouvelle plate-forme maximise la r\u00e9utilisation de l’historique avec un effort de d\u00e9veloppement minimal pour tirer parti des gains en termes de consommation d’\u00e9nergie et de r\u00e9duction du poids et de la complexit\u00e9 du faisceau de c\u00e2bles dans le v\u00e9hicule.<\/p>\n

La plate-forme de solution de virtualisation ECU combine les microcontr\u00f4leurs RH850\/U2x de Renesas avec le logiciel RTA-HVR d’ETAS, un hyperviseur con\u00e7u pour les microcontr\u00f4leurs avec prise en charge de la virtualisation mat\u00e9rielle. Cette plate-forme fournit un environnement de d\u00e9monstration pr\u00eat \u00e0 l’emploi comprenant des logiciels int\u00e9gr\u00e9s pr\u00e9configur\u00e9s, des outils et un environnement de d\u00e9monstration interactif pour les microcontr\u00f4leurs RH850\/U2x, permettant aux clients automobiles d’explorer les choix de conception pour le d\u00e9veloppement de leur propre projet Zone-ECU.<\/p>\n

\u00ab\u00a0La transition vers une architecture de zone augmente la charge de conception en modifiant les attributions de r\u00f4les fonctionnels entre l’ECU central et chaque ECU de zone\u00a0\u00bb, a d\u00e9clar\u00e9\u00a0Satoshi Yoshida, directeur principal, Division du marketing des produits num\u00e9riques automobiles chez Renesas. \u00ab\u00a0En plus des hautes performances fournies par les microcontr\u00f4leurs RH850\/U2x, je suis convaincu que cette nouvelle plate-forme de solution de virtualisation de calculateur offrira \u00e0 nos clients l’avantage d’un d\u00e9veloppement simple et rapide de syst\u00e8mes avanc\u00e9s avec des fonctionnalit\u00e9s de s\u00e9curit\u00e9 int\u00e9gr\u00e9es.\u00a0\u00bb<\/p>\n

\u00ab En travaillant avec Renesas, nous avons pu tirer parti des capacit\u00e9s mat\u00e9rielles des microcontr\u00f4leurs RH850\/U2x pour fournir un hyperviseur int\u00e9gr\u00e9 hautes performances et \u00e0 faible surcharge pour les applications automobiles qui compl\u00e8te les technologies AUTOSAR OS de pointe \u00bb, a d\u00e9clar\u00e9\u00a0Nigel Tracey, vice-pr\u00e9sident de Syst\u00e8mes d’exploitation des v\u00e9hicules chez ETAS.<\/p>\n

Le logiciel\u00a0RTA-HVR d’ETAS<\/a>\u00a0fonctionne avec les fonctionnalit\u00e9s de virtualisation mat\u00e9rielle des microcontr\u00f4leurs Renesas RH850U2x pour fournir une ou plusieurs machines virtuelles (VM). Les machines virtuelles sont s\u00e9par\u00e9es les unes des autres dans l’espace (\u00e0 l’aide de l’unit\u00e9 de protection de la m\u00e9moire du RH850U2x et des fonctions de protection) et dans le temps (\u00e0 l’aide du planificateur de machines virtuelles RTA-HVR) pour r\u00e9pondre aux exigences strictes de s\u00e9curit\u00e9 automobile. RTA-HVR fournit une bo\u00eete \u00e0 outils pour cr\u00e9er une extension de p\u00e9riph\u00e9rique virtuel (VDE). Chaque machine virtuelle comprend un ou plusieurs c\u0153urs de CPU virtuels, un sous-ensemble d’espace m\u00e9moire de p\u00e9riph\u00e9rique et une collection de p\u00e9riph\u00e9riques.<\/p>\n

Kit de d\u00e9marrage RH850\/U2x Zone-ECU<\/p>\n

Le kit de d\u00e9marrage d\u00e9di\u00e9 RH850\/U2x Zone-ECU est disponible dans le cadre de la solution. Le nouveau kit fournit une configuration \u00ab\u00a0pr\u00eate \u00e0 l’emploi\u00a0\u00bb de RTA-HVR pr\u00e9sentant diff\u00e9rentes configurations de VM (mono-c\u0153ur, multic\u0153ur et multi-VM par c\u0153ur). Des images logicielles invit\u00e9es sont fournies pour chacune des machines virtuelles configur\u00e9es, y compris des images \u00ab\u00a0bare metal\u00a0\u00bb et invit\u00e9es utilisant la solution RTA-CAR Classic AUTOSAR d’ETAS. Il propose des exemples de p\u00e9riph\u00e9riques virtuels pour le partage de p\u00e9riph\u00e9riques et la mise en r\u00e9seau virtuelle entre VM (un \u00ab\u00a0CAN virtuel\u00a0\u00bb).<\/p>\n
