Renesas Electronics updates model-based development environment to significantly simplify software development for multi-core automotive control microcontrollers
The RH850's model-based development environment supports the development of multi-cycle control (multiple control cycles) systems.
Tokyo, Japan, June 14, 2018 – Renesas Electronics Corporation (TSE: 6723), the world's leading supplier of automotive semiconductor solutions, today announced the update of its "Embedded Target for RH850 Multicore" model-based development environment. A multi-core microcontroller (MCU) for developing automotive control applications. The updated development environment will support the development of multi-cycle control (multiple control cycle) systems that are already common in systems such as engine and body control. Even in the software development scenario of multi-core MCUs, this model-based development environment is practical and can reduce the burden of increasingly complex software development, especially for the development of control systems for autonomous vehicles.
Renesas Electronics' early RH850 Multicore model-based development environment automatically distributed software to multiple cores. Although performance can be verified, in complex systems with multi-cycle control, all software must be implemented manually, including RTOS and device drivers. . Now, in order to meet the ever-increasing requirements for engine and vehicle performance, and to shorten product development time, multi-cycle control supported by the development environment can directly generate multi-core software code from the multi-cycle control model, thereby enabling evaluation and execution in simulation. performance. Not only can performance be estimated at the earliest stages of software development, but the results can be easily fed back to the model itself. The integrity of system development is improved early in the development process, and the burden of developing larger and more complex software systems can be significantly reduced. Renesas Electronics is accelerating the practicality of a model-based development environment for multicore processor software development and, as advocated by the Renesas AutonomyTM concept, leads the development of green electric vehicles.
Renesas Electronics will begin offering the updated "Embedded Target for RH850 Multicore" model-based development environment in the fall of 2018. For this release, Renesas Electronics will demonstrate the development environment at the 2018 MathWorks Automotive Symposium at the Shinagawa Tokyo Convention Center on Tuesday, July 3, 2018.
"The model-based development is becoming more and more common," Renesas Electronics has built an overlay from control design to automatic code generation, said Hiroshi Hiroshi, vice president of collaborative research and development at Renesas Electronics Automotive Solutions. Development environment. At the same time, due to the complexity of multi-core software, it is difficult to process this software code in the early model-based development environment. With the expertise in the use of automotive control scenarios, we have been researching this technology for a long time. Practical application and successful implementation of the development environment update. I believe that our model-based development environment will significantly improve the efficiency of multi-core microcontroller software development."
Key features of the updated "Embedded Target for RH850Multicore" model-based development environment
Support multi-cycle control, which can significantly reduce the development burden of multi-core software
Control function development requires multi-cycle control, such as intake/exhaust cycles in engine control, fuel injection and ignition cycles, and vehicle status verification cycles. These are all different cycles. The control mode can generate RH850 multi-core code, and the technology can be directly generated into multi-core code by applying multi-cycle control. Even models with multiple cycles (such as engine control) can directly generate multi-core code. Renesas Electronics also offers an option for the RH850 Integrated Development Environment CS+, a cycle accuracy simulator that accurately measures time and aligns with the actual system. Use this option to estimate the performance of a multicore MCU model in the early stages of software development. This will significantly shorten the software development cycle.
Compliance with JMAAB Control Modeling Guidelines for Industry Practice Standards Based on Automotive Model Development
JMAAB (Japan MBD Automotive Advisory Committee) is an organization dedicated to promoting model-based development of automotive control systems. The organization recommended several control models in the JMAAB Control Modeling Guidelines. Among them, the Simulink® scheduler block provided by Renesas Electronics in this update conforms to the (Alpha) type, and a scheduling layer is set in the upper layer. This allows it to follow the multi-cycle single-task approach without the operating system, execute the core specifications in the Simulink® model and synchronize, then automatically generate RH850 multi-core code for deterministic operation.
Overall operational verification of multi-system integrated ECUs
With the continuous improvement of the degree of control of automotive electronics, the ECU (Electronic Control Unit) of smaller-scale systems is also developing toward integration. By supporting multi-cycle control, it is now possible to make multi-core microcontrollers easier to operate small systems with different control cycles to verify the operation of the entire ECU that integrates multiple systems.
This fall, the new model-based development environment enables support for dual-core Renesas Electronics RH850/P1H-C MCUs, while support for up to six-core RH850/E2x series MCUs is also planned. In addition, Renesas Electronics plans to deploy this development environment to the entire Renesas Autonomy platform, including the "R-Car" series SoC. Renesas Electronics is committed to further improving the efficiency of model-based software development, including model-based parallelization tools from partner companies, and strengthening related performance evaluations that support multi-cycle control, including evaluation of operating systems. Looking ahead, as the complexity and scale of the industry continue to increase, Renesas Electronics plans to apply the model-based design expertise accumulated in automotive electronics development to the growing "RX" family of industrial applications.
The CAT6A 10Gig UTP modular jacks provide transmission performance beyond 500MHz and Alien Crosstalk requirements exceeding the industry standards set by ANSI/TIA-568-C.2 for supporting the operation of 10Gig Ethernet applications (10GBASE-T). It is designed with a shielded termination cap which minimizes additional AXT from neighboring connectors. It also features twisted pair separation posts which minimize the untwisting of pairs to allow for efficient installation and long-term peak performance. The modular jacks are also backward compatible supporting current CAT6, CAT5e, and voice network applications.
