A conduit for communication SoC carries out a variety of duties, including highly reliable data processing for vehicle control and a lot of random data exchange with cloud services and other services.
Vehicle control is crucial to guaranteeing safety, and it’s imperative to safeguard and separate mission-critical data. A communication hub SoCs conduct a variety of duties, including data processing for vehicle control, which demands a high level of reliability, as well as massive amounts of random data communication with cloud services and others.
The same in-vehicle network, despite the fact that different data types are used, is used to transfer all data, creating physical crossings and causing security concerns. Renesas created security technology that examines incoming packets to the SoC to solve this problem. It evaluates if they contain crucial information before allocating them to various channels and control operations within the network accelerator.
This shields in-vehicle data connectivity from a range of security risks and avoids interference with data that needs high reliability. In addition to serving as a data router and a central processing unit between different vehicle network domains, gateways facilitate communication within a vehicle network system.
Gateways enable communication within a car network system and so serve as both a data router and a central processing unit connecting vehicle network domains.
The gateway is responsible for converting information, data, or other communications from one protocol or format to another. Some gateway functions may be performed by a router. An Internet gateway is a device that connects an enterprise network to the Internet.
The Global automotive communication gateway SoC market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Renesas Creates Technologies for Automotive Communication Gateways SoCs Renesas Electronics Corporation (TSE: 6723), a leading provider of advanced semiconductor solutions, announced today that it has developed four technologies for system-on-chip (SoC) devices for in-vehicle communication gateways.
These SoCs are expected to play a critical role in creating the next-generation electrical/electronic (E/E) architecture in automotive systems.
SoCs for automotive gateways must have both high performance for implementing new applications such as cloud services and low power consumption when not in use. They must also provide a quick CAN response to support speedy start-up.
Furthermore, these SoCs must include power-efficient communication technology that allows network functions as a gateway to be performed with minimum power, as well as security technology that allows safe connection outside the vehicle.
To meet these requirements, Renesas developed an architecture that dynamically changes the circuit operation timing to match the vehicle conditions while optimising performance and power consumption, fast start-up technology by partitioning and powering only essential programmes, a network accelerator with a power efficiency of 10 gigabits per second/watt (Gbps/W), and (4) security technology that prevents communication interference by recognising and protecting against malicious code.
The R-Car S4 system on chips and power management ICs launched by Renesas Electronics Corporation, a leading provider of advanced semiconductor solutions, are ideal for next-generation car computers, communication gateways, domain servers, and application servers.
With E/E architectures evolving into domains and zones, Renesas’ innovative solution satisfies the high needs of the automobile sector for high performance, high-speed networking, high security, and high functional safety levels.
The technology also greatly increases development productivity by allowing software reuse and incorporating the newest, top-of-the-line PMICs created specifically for the R-Car S4. Advanced power modes that permit extremely low power operation are offered by the new PMICs for R-Car.
The RAA271041 PMIC accepts the vehicle’s 12V power source and offers first-stage control while supporting wide operation for load dump and cold cranking pulses.
The RAA271005 is a Safe 11-channel PMIC that scales down the output of the RAA271041 to the several supply voltages required by the R-Car S4 and its accessories, including LPDDR4x memory. From the vehicle battery down to system voltage, the RAA271041 and RAA271005 PMICs offer a whole power solution.
A proof of concept (PoC) exhibiting a communication gateway ECU based on an open standard software model employing a SOA on in-vehicle SoC (System on Chip) components from Renesas Electronics was released by eSOL.
The PoC is intended to pave the way for the creation of central computing ECUs for complex automotive functions like V2X communication and tackles the problem of supporting the most cutting-edge automotive designs.
The PoC uses heterogeneous eMCOS profiles and the Renesas R-Car S4 SoC’s heterogeneous multiprocessor architecture to run on the multikernel eMCOS RTOS platform. Real-time performance, energy efficiency, and system adaptability are all features of this design.
Functionalities like V2X, OTA, and other new services for the driver are made possible by connecting the ECUs with a communication gateway that connects the control units to one another and securely connects the car to the cloud.
These heterogeneous computing systems’ software will be created using the SOA, and after booting, the heterogeneous hardware will be controlled safely and securely by eSOL’s eMCOS RTOS platform. Due to the distinctive multikernel architecture of each eMCOS profile, it offers the highest possible multicore performance and FFI.
At the same time, it ensures information sharing between programmes on all heterogeneous cores with its lightweight inter-process communication characteristics.
The IPMMU and heterogeneous security hardware are both supported by the current eMCOS board support package for the R-Car S4 to allow the RTOS to safely control all peripherals.
A high-performance 3-port Ethernet switch from Renesas with support for the most recent IEEE TSN standard is also supported, the R-Switch 2. Several eMCOS profiles are utilised in the PoC. The high-performance 8x Arm Cortex-A55 cores run the eMCOS Hypervisor, and the Cortex-R52 core launches an eMCOS AUTOSAR profile based on an AUTOSAR Classic platform.
Additionally, two RH850 G4MH cores are used to attach the AUTOSAR Classic Platform. The eMCOS hypervisor virtualizes the high-performance 8x Cortex-A55 cores in real-time to host AUTOSAR AP guests on Linux or eMCOS POSIX.
This type 1.5 hypervisor also allows for the simultaneous hosting of native POSIX processes, which is a benefit over legacy type 1 hypervisors.
The central gateways will support an increasing number of data bus systems as a hub for communications among the various ECUs. By enabling cloud connectivity, these bus systems will aid in the establishment of intricate communication networks. They will also check for Over-The-Air (OTA) software updates for car systems and transmit them to the appropriate locations.
