说明：  ITRON（Industrial the Real-Time Operation System Nucleus，工业实时操作系统中心）提出的实时多任务系统规范。它具有标准的实时内核，适用于任何小规模的嵌入式系统，日本国内现有很多基于该内核的产品，其中消费电器较多，目前已成为日本事实上的工业标准。 ITRON和日本的精密机械工业相结合，使日本在数据系统、工业机器人、办公机器方面处于世界领先地位。
(ITRON (Industrial and the Real-Time Operatio n System Nucleus, industrial real-time operating system) the real-time multi-task system of norms. It is the standard real-time kernel, applies to any small-scale embedded systems. Japan based on the many existing core products, including consumer appliances more, Japan has become the de facto industry standard. ITRON and Japan's precision machinery industry combined, the Japanese data systems, industrial robots, office machinery at the world's leading position.)
