Safe and secure virtualization for embedded microcontrollers with µ-visor
First implementation of µ-visor available on Renesas RH850/U2A MCU provides the essential foundation for ECU consolidation in automotive designs.

The Renesas RH850/U2A is the first MCU with embedded flash that integrates a hardware-based virtualization-assisted function while maintaining the fast, real-time performance that customers expect of the RH850 products. The hardware virtualization function supports ISO 26262 ASIL D functional safety, enabling greater levels of system integration of the safety applications of automotive OEMs and Tier 1s into a single, unified MCU-based electronic control unit (ECU). To support ASIL D, the hardware-based virtualization technology allows customers to implement multiple software services with different functional safety levels on the RH850/U2A MCU that can run concurrently without interference while maintaining the hard real-time deterministic performance required to control modern and future vehicle functions. µ-visor from Green Hills Software fully supports all of these advanced capabilities.

“Green Hills Software’s virtualization technology for application processors is already in production in tens of millions of vehicles today,” said Matthew Slager, Vice President of Asia-Pacific Operations at Green Hills Software. “By extending our virtualization technology expertise and experience into the MCU market with µ-visor and working with Renesas, Green Hills Software can offer best-in-class performance, functional safety and cybersecurity on the RH850/U2A, allowing automotive customers to achieve the challenging goals of developing and deploying highly performant and entirely safe and secure ECU consolidation.”
