Overview


eSOL was among the first companies to introduce a real-time operating system (RTOS) for multi-core processors: the eT-Kernel MCE (*Multi-Core Edition). The eT-Kernel MCE incorporates eSOL’s unique Blended Scheduling technology, which allows both Symmetrical Multi-Processing (SMP) and Asymmetrical Multi-Processing (AMP) subsystems to coexist on a single system. It offers high compatibility with Linux with its POSIX support. A system protection feature for protecting memory and CPU time is provided to streamline systems integration and ensure real-time determinism, as well as high reliability for multi-core system deployments. The eT-Kernel MCE is widely used in systems such as car navigation systems and printers.


In anticipation of increased use of many-core processors in embedded systems in the future, eSOL developed eMCOS as the world’s first commercially available RTOS that supports many-core processors for embedded systems. Many-core processors achieve optimal energy efficiency and performance scalability by increasing or decreasing the number of cores in use according to processing requirements. Thanks to their features, many-core processors are ideal for advanced embedded systems requiring precise control with minimal power consumption, such as image recognition, cyber-physical security and devices, medical, and energy systems as well as networking, automotive, transportation, and robots.

Based on the advanced technical skills and practical know-how cultivated by developing these products, eSOL is a leading provider of software development solutions for multi-core and many-core processors.
