[Japanese] [English]

The ITRON Project creates standards for real-time operating system specifications for embedded systems and related specifications. Many products have been developed based on the ITRON specifications, and now ITRON is a de-fact standard operating system specification for small-scale embedded systems in Japan. The ITRON Project is promoted by the ITRON Specification Group in the TRON Association, as one of the subproject of the TRON Project.
