The eT-Kernel real-time operating system (RTOS) is designed for embedded systems that require high performance and reliability. eT-Kernel has product certification for the highest safety levels under both the ISO 26262 (for automobiles) and IEC 61508 (for industrial equipment) functional safety standards (the ASIL D and SIL 4 safety levels, respectively). eSOL has also obtained certification that its development processes for RTOS products comply with the IEC 62304 safety standard for medical devices. eT-Kernel is based on the open TRON architecture which is the most widely adopted in embedded systems in Japan and Asian countries.
