Tokyo, Japan and Santa Barbara, U.S.: Renesas Electronics Corp. and Green Hills Software will jointly develop basic software supporting CPU virtualization technology suitable for real-time control applications as well as a software development environment.
Through the collaboration, Renesas will develop the added functions necessary for the efficient operation of virtualization software enabling high-speed real-time control and improving the usability of the software development environment, incorporating these functions into microcontrollers (MCUs) with the V850 CPU core.
Green Hills Software will port the Multi integrated development environment (IDE), which includes components such as a compiler and a debugger that already support the Renesas V850 core. The new CPU virtualization technology will support software that enables multiple applications to run independently and simultaneously on a single CPU, such as the Integrity real-time operating system (RTOS).
The Green Hills IDE will generate compact and high-speed instruction code optimized for the CPU virtualization technology provided by the V850 core. Combined with virtualization software such as Integrity Secure Virtualization, which supports safety standards such as IEC 61508 (Note 1), the software development environment will deliver the means to develop and implement with high efficiency applications with excellent functional safety. There are also plans to include support for the emerging ISO 26262 functional safety standard.
Renesas has been developing CPU virtualization technology for the V850 architecture to enable the control of multiple systems with a single CPU core without mutual interference, allowing high-speed and composite control in fields such as industrial machinery and automotive systems, where real-time control is essential. The software development environment will be available through Green Hills Software as part of the Multi product family.
