Press Release
Tokyo, Japan, April 3, 2018
TRON RTOS API holds 60 percent or more of the share of the API ofembedded OS in use. TRON specification OS has been the most popular
embedded OS for the 22 consecutive years.
— TRON Forum has published the “FY2017 Survey Report on Embedded
Real-time OS Usage Trends” to its members, and plans to sell it to corporate
customers from the middle of April.

TRON Forum (Location: Shinagawa, Tokyo, Chair: Ken Sakamura, Dean of INIAD(Information Networking for Innovation and Design), Toyo University) is a proponent ofTRON Project, and aims to establish the Open IoT environment that is free ofrestrictions imposed by organizations or applications by using open source, open dataand open API.
It has compiled “FY2017 Survey Report on Embedded Real-time OS Usage Trends.” The
result shows that approximately 60 percent of the share of "the API of embedded OS inuse” is held by T-Kernel specification API (including μT-Kernel specification API) andITRON specification API. The result shows that TRON RTOS family has occupied thetopmost share for the 22 consecutive years since the start of the survey. Also, in thebreakdown of embedded OS usage in different application fields, TRON RTOS family
occupies the topmost share in the IoT-related devices.
This survey has been held as periodic annual measurement for 22 times so far at thevenue of Embedded Technology (ET, organized by Japan Embedded Systems Technology
Association: JASA) and its predecessor. The latest FY2017 Survey Report summarizes
the result of the questionnaire answered by the respondents through the special website
for this survey or on the premise of ET2017 (Embedded Technology 2017) which washeld in PACIFICO YOKOHAMA from November 15 to 17, 2017.
TRON Forum publishes the whole content of the survey result on the members-only
web pages for Executive Committee/A-/i-/B-/Academic members. If corporations and themembers other than the above need the survey result, “Limited to a division-only
readership version (100,000 yen excluding tax)” and “Company-wide readership version(200,000 yen excluding tax)” will be on sale through the web shop(http://www.personal-media.co.jp/webshop/) operated by Personal Media Corporation,
one of the Executive Committee members of TRON Forum, from the middle of April.

TRON Forum Research and Study WG conducted this survey. Comments from theWG Chair are in TRONWARE VOL.170, the TRON & IoT technology information
