Three team for I/O aggregator gateway
Green Hills Software has worked with Infineon Technologies and Cetitec to create a cost-efficient, pre-programmed I/O aggregator gateway for vehicle communication networks.
The gateway is based on the Infineon Traveo T2G MCU with the safety-certified µ-velOSity RTOS from Green Hills integrated with Cetitec’s Universal Gateway middleware. This provides a lower-cost, low-latency vehicle I/O aggregator gateway platform for Ethernet-based vehicle networks.
In the vehicle network, the I/O aggregator gateway is positioned between the domain or zonal controller and the vehicle’s sensors and actuators. A less complex wiring harness efficiently translates and forwards CAN and LIN messages to Ethernet messages and controls edge node peripherals including support for GPIO, SPI, UART and PWM signals.
Unlike programmable controllers, the I/O aggregator is pre-programmed for immediate use and enables updates without firmware changes via remote access and configuration through the domain or zonal controller. The combined platform gives system architects a more streamlined option towards realizing lower-cost, optimized safety-certified zonal architectures having to manage many disparate vehicle buses.
The µ-velOSity safety RTOS runs the Cetitec embedded I/O gateway software stack on the Traveo T2G MCU. This dupports the IEEE1722-ACF protocol for Ethernet, CAN and LIN communication and implements the Remote Control Protocol (RCP) for edge-node peripheral control for GPIO, SPI, UART, and PWM.
“The Traveo T2G is the ideal foundation for efficient I/O aggregation in zonal architectures,” said Ralf Ködel, Vice President, Microcontroller Smart Mobility at Infineon. “This I/O aggregator solution is a low-memory, cost-optimized design with a ready-to-use software stack from Green Hills and Cetitec to offer maximum flexibility for our customers.”
“Our long-term collaboration with Infineon and Green Hills translates into cutting-edge initiatives,” said Dr. Michael Back, CEO at Cetitec. “This I/O aggregator solution empowers zonal architectures, while ensuring efficiency, flexibility, and reuse of well-tested components.”
“This production-focused I/O aggregator solution provides our customers timely access to a platform with optimized management of the many different vehicle buses that remain as part of today’s vehicle architectures,” said Dan Mender, VP, Business Development at Green Hills Software. “And, by utilizing the Green Hills µ-velOSity safety RTOS with the MULTI advanced debugger, customers can achieve a lower-cost, faster-time-to-production approach for these system designs.”
The I/O aggregator platform is available today and on show at the embedded world exhibition in Nuremberg this week.
