Sixty percent or more of the share is held by TRON RTOS API for the API of embedded
OS in use. This means TRON specification OS has been the most popular OS for the 25
consecutive times.
̶ TRON Forum has published to its members the "FY 2023 Survey Report on Embedded
Real-time OS Usage Trends" for the first time in four years.
TRON Forum (Location: Shinagawa, Tokyo, Chair: Ken Sakamura, Professor Emeritus, theUniversity of Tokyo), which is a proponent of TRON Project, and aims to establish the Open IoTenvironment that is free of restrictions imposed by organizations or applications by using opensource, open data and Open API, has compiled “FY 2023 Survey Report on Embedded
Real-time OS Usage Trends.” The report shows that approximately 60 percents of the share of"the API of embedded OS in use" is held by API of the T-Kernel specification API including μT-Kernel specification API, etc. and ITRON specification API. This means that the TRON RTOS
family has occupied the topmost share for the 25 consecutive times since the start of thesurvey.
As a result of this survey, the following points can be noted.
・The TRON Real-Time OS (RTOS) family has been recognized as an IEEE Milestone, and theawareness overseas may have increased accordingly.
・TRON RTOSs are gaining wider recognition in Japan as well.
This survey has been held as annual measurements for 25 times so far at the venue of
EdgeTech+ 2023 (Organizer: Japan Embedded Systems Technology Association: JASA, Venue:
PACIFICO YOKOHAMA) and its predecessors. The latest FY 2023 Survey Report summarizes
the result of the questionnaire answered by the respondents through the special website for thissurvey and the visitors to EdgeTech+ 2023 which was held from November 15 to 17, 2023.
