As the penetration rate of intelligent vehicles rises, Advanced Driver Assistance Systems (ADAS) and Autonomous Driving Systems (ADS) impose increasingly stringent requirements on storage reliability, real-time performance, and security. Automotive-grade eMMC, with its balanced performance and cost advantages, has emerged as a core storage component supporting the stable operation of these two systems, providing critical safeguards for intelligent driving data processing.
ADAS Applications
In ADAS, automotive-grade eMMC undertakes dual responsibilities of real-time data interaction and core algorithm storage. Functions such as adaptive cruise control and lane departure warning require continuous collection of real-time data from cameras and radars. Leveraging the HS400 high-speed mode, automotive-grade eMMC achieves a maximum read speed of 400MB/s, ensuring rapid algorithm model invocation and zero-latency transmission of decision-making instructions. Meanwhile, certified to AEC-Q100 standards, it operates stably in extreme temperatures ranging from -40℃ to 105℃, resisting vehicle vibrations and electromagnetic interference, thus preventing system misjudgments caused by data loss.
Autonomous Driving Systems Support
For ADS, automotive-grade eMMC focuses on supporting high-precision map storage and dynamic data caching. The 128GB-class automotive-grade eMMC can store static high-precision map data covering major urban agglomerations, while reserving buffer space for dynamic traffic information. Thanks to its execute-in-place (XIP) feature, map data can be run directly without being copied to RAM, with loading latency kept below 50ms, ensuring trajectory control accuracy in complex scenarios such as ramp navigation. In addition, its built-in hardware encryption and secure boot functions prevent algorithm data tampering and malicious program injection, building a solid security defense for ADS.
Long-Lifecycle Design
The long-lifecycle design of automotive-grade eMMC is tailored to meet the full-lifecycle needs of intelligent driving. Equipped with global wear-leveling algorithms and high erase-cycle endurance, it satisfies the high-frequency data read/write and OTA upgrade requirements of ADAS/ADS. Some high-spec products boast an erase lifespan of up to 30,000 cycles, far exceeding conventional storage standards. Moreover, emergency power-off protection and ECC error correction technologies ensure the complete retention of driving data, providing reliable data support for fault tracing and algorithm optimization.
In summary, with its extreme environmental adaptability, high-speed data transmission, and robust security protection, automotive-grade eMMC serves as the data security cornerstone of ADAS and ADS, playing an irreplaceable supporting role in the evolution of intelligent driving technologies.
