New Electronics – Renesas debuts Automotive ECU Virtualization Solution Platform


Renesas Electronics has announced an built-in automotive Eu Virtualization System that will permit designers to combine various applications into a one Ecu (Digital Regulate Device) that are properly and securely separated from just about every other to stay clear of interference. &#13

The solution enables clients to adopt new electrical-digital (E/E) architectures utilizing MCU-based mostly zone ECUs supporting a number of sensible ECUs on 1 actual physical Ecu. Migration to the new platform looks to maximise legacy reuse with the minimum amount of progress exertion to support leverage gains in reduce power consumption and reduced wiring harness fat and complexity in the car or truck.

The European virtualization alternative platform brings together Renesas’ RH850/U2x MCUs collectively with ETAS’ RTA-HVR computer software, a hypervisor designed for microcontrollers with hardware virtualization assist. This system delivers a ready-to-use demonstrator environment comprising pre-configured embedded application, tools and an interactive demonstrator ecosystem for RH850/U2x MCUs, allowing for automotive buyers explore structure selections for the development for their specific Zone-European project.

 “The changeover to a zone architecture improves the design load by shifting the useful job assignments concerning the central Ecu and each individual zone European,” reported Satoshi Yoshida, Senior Director, Automotive Electronic Solutions Internet marketing Division at Renesas. “In addition to the higher general performance delivered by the RH850/U2x MCUs, I am assured that this new Ecu Virtualization Solution System will give our shoppers the benefit of straightforward, quick enhancement of innovative units with developed-in basic safety and protection features.”

“Working together with Renesas, we had been able to leverage the HW capabilities of the RH850/U2x MCUs to supply a large overall performance, lower overhead, embedded hypervisor for automotive purposes that enhances class-leading AUTOSAR OS technologies” stated Nigel Tracey, Vice President of Car or truck Working Programs at ETAS.

The RH850/U2x MCUs which include RH850/U2A and RH850/U2B are supposed to deliver a charge-efficient and substantial-performance remedy for future technology Zone-/Integration-ECUs due to a prosperous set of embedded components that realizes the integration of many ASIL D-compliant software package partitions.

The MCUs are exclusively developed for Zone-applications focusing on decreased Ecu part rely with small re-engineering overhead. RH850/U2x MCUs contain capabilities these as Hypervisor components assistance, Good quality-of-Company (RH850/U2B only) aid, Security & Security features to help independence from interference, and a high-efficiency NoC (Network-on-Chip) construction to assure correct genuine-time behaviour of the particular person integrated applications.

ETAS’ RTA-HVR software performs with the hardware virtualization options of the Renesas RH850U2x MCUs to supply just one or much more virtual equipment (VMs) which are separated from every other in each space (using the RH850U2x memory security unit and guard features) and time (using the RTA-HVR VM scheduler) to fulfill demanding automotive security and stability needs.

RTA-HVR supplies a toolkit to make a digital gadget extension (VDE). Each and every VM includes one particular or more virtual CPU cores, a subset of machine memory place and a collection of peripherals.

The RH850/U2x Zone-Eu Starter Kit is accessible as aspect of the alternative and provides a “ready-to-run” configuration of RTA-HVR showcasing distinctive VM configurations (solitary core, multi-main and multi-VM for each main). Visitor computer software photos are supplied for every of the configured VMs, such as bare steel and visitor images employing ETAS’s RTA-Auto Basic AUTOSAR remedy. It provides illustration virtual devices for peripheral sharing and digital inter-VM networking (a “virtual CAN”).

In addition, a Personal computer-hosted software allows people to observe and interact with the VMs at runtime. The Computer application supports a lot of steps which include:

  • Triggering faults in the procedure at runtime to discover VM behaviour through memory violations, timing overruns and so on.
  • Updating one VM though the other VMs are operating utilizing the no-wait around OTA abilities of the RH850/U2x.
  • Discovering the effectiveness influence of choice VM switching mechanisms
  • Enabling developers to see the impact of HW QoS options

The Eu Virtualization Program System, like the RH850/U2x Zone-European Starter Package, is available from Renesas starting off from the close of May
