Abstract: With the gradual shift of electronic and electrical architecture from distributed to centralized and the proposal of the concept of "software-defined vehicles", service-oriented architecture has also been applied and implemented in automotive electronic development and software design. Based on the next-generation centralized electronic and electrical architecture, this article develops and designs a vehicle-mounted intelligent gateway controller using the NXP dedicated gateway control chip S32G399. The data processing and routing forwarding of the controller's local area network and Ethernet have been efficiently achieved by leveraging the low-latency communication engine, data packet forwarding engine, hardware acceleration engine of the chip, and the protocol stack of the automotive development system architecture based on the classic platform. The automotive development system architecture protocol stack based on the classic platform is deployed on the Cortex-M7 core, and the automotive development system architecture protocol stack based on the adaptive platform is deployed on the Cortex-A53 core. The signal to service is deployed and implemented based on the service-oriented software architecture. The transformation and processing of signals and services are achieved on the Cortex-M7 and Cortex-A53 cores, which greatly enhanced the intelligence of the gateway controller.
