An automotive platform solution from Renesas Electronics Corp. and TTTech Computertechnik AG provides an electronic control unit (ECU) development platform for advanced driver assistance systems (ADAS). The platform integrates Renesas’ RH850/Plx automotive control microcontroller (MCU) and R-Car system-on-chips (SoCs) with TTTech’s TTIntegration software platform to enable highly complex automotive solutions, including automated driving. The platform achieves parallel, multi-vendor development and integration of individual software components. Centerpieces of TTTech’s ADAS platform are TTIntegration and Deterministic Ethernet. TTIntegration is located and runs as middleware between the CPU level and the integrated applications. It provides each application with the CPU time and memory it needs, while separating or even abstracting hardware from applications. Delivering an AUTOSAR environment for various operating systems enables system manufacturers to move applications between the embedded cores more easily. TTIntegration supports various safety levels simultaneously. A strict partitioning concept ensures at any time that a bug or defect in one application cannot harm any other or cause a collapse of the whole ECU. The concept grants “Freedom of Interference” as demanded by the highest automotive development safety norms. The platform solution uses TTTech’s Deterministic Ethernet, a reliable and real-time capable Ethernet backbone solution, for the communication.
