ECU virtualization solution eases automotive system development
TheZone-ECU Virtualization Solution Platform, says the company, enables customers to adopt new electrical-electronic (E/E) architectures using MCU-based zone ECUs supporting multiple logical ECUs on one physical ECU. Migration to the new platform maximizes legacy reuse with minimum development effort to leverage gains in lower power consumption and reduced wiring harness weight and complexity in the vehicle.
The ECU virtualization solution platform combines the company’sRH850/U2X MCUS和...一起ETAS的RTA-HVR软件，为具有硬件虚拟化支持的微控制器设计的管理程序。该平台为RH850/U2X MCUS组成的预配置嵌入式软件，工具和交互式演示器环境提供了一个现成的演示器环境，使汽车客户可以为其各个区域ECU项目探索开发的设计选择。
“The transition to a zone architecture increases the design burden by changing the functional role assignments between the central ECU and each zone ECU,” says Satoshi Yoshida, Senior Director, Automotive Digital Products Marketing Division at Renesas. “In addition to the high performance provided by the RH850/U2x MCUs, I am confident that this new ECU Virtualization Solution Platform will give our customers the advantage of easy, fast development of advanced systems with built-in safety and security features.”
作为解决方案的一部分，可用的是RH850/U2X区域ECU启动器套件，该套件提供了RTA-HVR的“现成运行”配置，展示了不同的VM配置（单核，多核和多核/核心）。为每个配置的VM提供了来宾软件图像，包括使用ETAS的RTA-CAR经典Autosar解决方案，包括裸机和来宾图像。它提供了用于外围共享和虚拟Inter-VM网络（“虚拟罐”）的示例虚拟设备。
In addition, a PC-hosted application enables users to observe and interact with the VMs at runtime. The PC application supports numerous actions including:
- Triggering faults in the system at runtime to explore VM behaviour during memory violations, timing overruns etc.
- Updating one VM while the other VMs are running using the no-wait OTA capabilities of the RH850/U2x.
- Exploring the performance impact of alternative VM switching mechanisms
- Enabling developers to see the impact of HW QoS features
The ECU Virtualization Software Platform, including the RH850/U2x Zone-ECU Starter Kit, is available from Renesas starting from the end of May.
