TIER IV Advances Level 4 Autonomous Driving SoC Research

TIER IV Advances AI Chip Development

TIER IV Level 4 Autonomous Driving SoC research is being advanced through participation in the Japan Science and Technology Agency’s Next-Generation Edge AI Semiconductor Research and Development Program. The TIER IV initiative will lead logic design for an AI chip intended to process inference efficiently for end-to-end autonomous driving AI. The project targets Level 4 applications and includes an objective to open-source the resulting design assets and associated toolchain, creating a foundation for broader industry participation in autonomous driving semiconductor development.

Open Ecosystem Built Around Autoware

Under the initiative, TIER IV will independently design an AI chip that supports Autoware, its open-source autonomous driving software platform, and evaluate the chip’s effectiveness within a software-defined system-on-chip. The work will also cover an open-source compiler and related toolchain, creating an opportunity for semiconductor manufacturers to use platform technologies developed by the company. The broader objective is to accelerate commercialization of SoCs for Level 4 autonomous driving through an open ecosystem, while enabling closer integration between autonomous-driving software and semiconductor technologies.

Addressing Real-Time Autonomous Driving Requirements

Level 4 autonomous driving places continuous demands on AI models operating under real-world and real-time constraints. The research therefore seeks an approach that complements existing high-performance computing technologies while advancing power efficiency, adaptability, transparency, and verifiability. By combining autonomous-driving software support with chip logic and an open development toolchain, the project is intended to address both processing requirements and the practical ecosystem needs associated with deploying advanced autonomous driving systems. The participation of Japan’s science and technology research framework further supports development of next-generation edge AI semiconductor capabilities.
