Analysis of the deterministic principle in EDMS and its application in the automotive industry

EDMS (formerly AOS) is a deterministic middleware framework designed to address the unique challenges of the automotive field, especially in the context of ADAS and autonomous driving, providing developers with the tools and integration capabilities needed to create high-performance and high-safety applications. Determinism in EDMS is reflected in two aspects: time determinism and data determinism. Time determinism focuses on the predictability and repeatability of system behavior relative to time, and data determinism focuses on the consistency and predictability of system behavior in data processing. In addition, deterministic recalculation and simulated driving provide a powerful solution for AD development and accelerate the development of AD systems.
