英飞凌谈车用RISC-V芯片：将颠覆行业格局

Core Viewpoint - The automotive industry is undergoing a transformation driven by software-defined vehicles (SDVs) and the adoption of RISC-V architecture, which is expected to redefine the industry's landscape and enhance collaboration between hardware and software [2][4][19]. Group 1: Key Priorities for Future Vehicles - Future vehicles require flexible platforms that can scale across computing domains to meet diverse performance, safety, and energy needs [3]. - The shift from distributed software to regional and centralized computing will simplify development processes and optimize costs for automakers [3]. - The transition to regional architecture will reduce wiring complexity and costs while improving latency and integration [3]. Group 2: Software Ecosystem - The software ecosystem is crucial for SDVs, with AUTOSAR being a leading standard supported by major OEMs and suppliers [4]. - The development of a RISC-V AUTOSAR software ecosystem is underway, with collaborations among various tech companies [4][5]. - Automotive-grade Linux (AGL) is being adapted for safety-critical applications, with community projects aimed at certifying Linux-based systems for critical use cases [4][5]. Group 3: Open Hardware - RISC-V's open, royalty-free instruction set architecture allows OEMs to gain long-term control and avoid reliance on single suppliers, fostering interoperability and innovation [8]. - The ability to optimize hardware and software co-design is a significant advantage of open hardware, enabling OEMs to customize RISC-V cores for specific vehicle needs [8]. - Building a resilient supply chain through open standards can facilitate easier vendor changes and reduce investment risks [8]. Group 4: Collaboration through Standards - Standardization is essential for ensuring system interoperability and scalability in the automotive industry [10]. - A unified standard can reduce complexity and enhance compatibility across the ecosystem, promoting cross-industry collaboration [10]. - The introduction of a common CPU safety concept could enhance reliability and security in automotive systems [12][13]. Group 5: Modularization - Modularization in semiconductor design allows for specific decisions regarding safety, reliability, and real-time performance [15]. - Chiplet technology enables clear hardware isolation between components that require different safety standards [16]. - Modularization supports the introduction of innovations from outside the automotive industry while maintaining necessary constraints [15]. Group 6: Regional Adaptability - Future vehicles must be customized to meet varying regulatory, safety, environmental, and consumer demands across different regions [17]. - A balance between localized customization and a consistent global architecture is crucial for efficiency [17]. - RISC-V's architecture can support regional adaptations while maintaining cost-effectiveness [18]. Group 7: Industry Momentum - The momentum for RISC-V in the automotive sector is growing, with suppliers actively discussing implementation details with OEMs [18]. - The automotive industry recognizes the unique advantages of RISC-V, indicating a strong commitment to its adoption [18].
