Renesas Electronics Upgrades Model-Based Development Environments For Smoothening Software Development Loads For Multicore Automotive Control Microcontrollers

Renesas Electronics Corporation, a leading supplier of semiconductor solutions, recently updated its ‘Embedded Target for RH850 Multicore” model based development environment for MCUs (Multicore Microcontrollers) for automotive control applications. The update of Embedded Target for RH850 Multicore” model based development environment provides full-on support to system development with multirate control, it is now a regular feature in systems like body and engine control systems. The model-based development environment is possible even with respect to software development scenarios for multicore Microcontrollers. These can easily bring down the rapidly rising software development loads specifically in control system development of self-driving vehicles.

The previous RH850 multicore model-based development environment from Renesas allocated software to multiple cores automatically. Although justified performance was attainable in complicated systems with multirate control, it was compulsory to implement every single thing manually including device drivers and RTOS.

But now, since they need to meet the rapidly expanding requirements for for better engine and vehicle performance as well as reduction of product development period simultaneously, the support for multirate control by development environment makes direct generation of multicore software code from multirate control model possible. It also allow the makers to estimate the execution performance in simulated stage. You can expect accurate estimation of of execution performance in juvenile stages of software development along with feedback of verification results in the model itself.

As the vice president of Shared R&D Division 1, Automotive Solutions Business Unit at Renesas Electronics Corporation, Hiroyuki Kondo, puts it, “Model-based development is becoming increasingly common, and Renesas has now completed an environment that covers from control design through automatic code generation. At the same time, since multicore software is complex, it was difficult to handle such software in earlier model-based development environments. Leveraging our extensive expertise in automotive control use cases, we were able to start working on practical application of this technology early on, and thus succeeded in creating this update. I am confident that our model-based development environment will bring dramatically improved efficiency in software development for multicore microcontrollers.”
