Extended T-Kernel RTOS
Contact us

eT-Kernel™ is an upgraded version of open source RTOS T-Kernel 2.0, extended with unique eSOL technology for embedded systems. Taking advantage of the specific T-License2.0 of T-Kernel 2.0, it can be commercialized without making the software open-source. Source code is provided to eSOL customers however to allow more efficient development and integration.

eT-Kernel Compact has been certified to the following Functional Safety standards.
  • ISO 26262 ASIL D (For automotive)
  • IEC 61508 SIL 4 (For industrial equipment)

In addition, the eSOL RTOS product development process has been certified in compliance with IEC 62304: 2006 Medical Device Software-Software Life Cycle Processes, which are safety standards for the development and maintenance of medical device software.

Product Line of eT-Kernel Safety Package

The core of all eT-Kernel profiles, eT-Kernel Compact, has been certified to the following Functional Safety standards.

  • ISO 26262 ASIL D (For automotive)
  • IEC 61508 SIL 4 (For industrial equipment)

Open source T-Kernel has been extended

As an RTOS vendor, eSOL has put great effort and know-how into enhancing T-Kernel 2.0 (distributed by TRON Forum) source code as a basis. When compared to open source T-Kernel, eT-Kernel offers the following additional features:

  • "Logical File System (LFS)" offers transparent access to multiple file systems
  • "Exception Manager" offers problem-solving support while the system is running
  • "Target Shell" adds extended commands, useful for final system maintenance and inspection
  • Multi-core compatibility using a unique scheduling method makes it possible to mix SMP and AMP
  • System protection function helps to ensure multi-core system quality and reliability
  • Unique verification in addition to standards test suite

Compatibility with T-Kernel is retained

eT-Kernel retains backward-compatibility with TRON Forum’s T-Kernel 2.0. eSOL is certified by Tron Forum to distribute a modified version of their product, so that you can use eT-Kernel with peace of mind.

Compact real-time OS

eT-Kernel Compact is analogous to μITRON compact RTOS with remarkable real-time capability.

Multi-core compatible, able to mix SMP and AMP

A multi-core compatible version called eT-Kernel MCE (*Multi-Core Edition) is available. Even when using the eT-Kernel MCE, an ideal profile can be selected from the option above. A unique "Blended Scheduling" technology allows mixing SMP-type programs and AMP-type programs in a single system. Also, a system protection function helps to ensure complex multi-core system quality and reliability.

Development environment - eBinder®

eBinder is available as a development environment for T-Kernel based embedded software development. It can be used for development with eT-Kernel Compact and eT-Kernel MCE. There is no need to learn how to use new development tools when you change your OS or profile, increasing the efficiency of the development process.

Logical File System supports POSIX file system APIs

A Logical File System (LFS) is provided, providing ANSI/POSIX file system APIs. It is fully integrated with the provided thread-safe C library. It can be called from anywhere, including processes and kernel applications including system programs. FAT file system is integrated as a standard file system that can be used via POSIX interface.

Successfully implemented in various fields

eT-Kernel has been successfully deployed in a wide range of diverse fields. It is also being used for numerous products that are currently under development.

Adoption Examples
