Through the collaboration, Renesas Electronics will develop 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 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 Renesas Electronics’ V850 core. The new CPU virtualisation technology will provide support for 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 Renesas Electronics’ V850 core. When combined with virtualization software such as INTEGRITY Secure Virtualization, which support safety standards such as IEC 61508, 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 Electronics has been developing CPU virtualisation technology for the V850 architecture to enable 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.
Green Hills Software has made a contribution to facilitating design procedures in virtualised environments through its virtualization software and the software development environment.
Renesas Electronics considers a full-fledged software development environment incorporating basic software that allows efficient use of virtualization technology to be essential.
The software development environment will be available through Green Hills Software as part of the MULTI product family.
