Abstract:
	The ITRON Subproject is to define and promote a standard
	operating system specification for embedded systems.  A series
	of ITRON real-time kernel specifications has been defined and
	published so far.  Among them, the $\mu$ITRON specifications,
	which are designed for small-scale embedded systems, have been
	aimplemented for a large number of microcontroller units (MCUs)
	and have been utilized in numerous applications.  In this
	paper, we describe the current status and recent results of
	the ITRON Subproject, after reviewing the design principles
	and the history of the ITRON specifications.  Then, we discuss
	the future directions of the subproject.
