>The &micro;ITRON specification
defines a highly flexible operating system architecture designed
specifically for application in embedded systems. The specification addresses
features which are common to the majority of processor architectures and
deliberately avoids virtualization which would adversely impact
real-time performance. The &micro;ITRON specification
may be implemented on many hardware platforms and provides significant
advantages by reducing the effort involved in understanding and
porting application software to new processor architectures. </P
><P
>Several revisions of the &micro;ITRON specification exist.
	In this release, <SPAN
CLASS="emphasis"
><I
CLASS="EMPHASIS"
>eCos</I
></SPAN
> supports the
	&micro;ITRON version 3.02 specification, with complete
	&#8220;Standard functionality&#8221; (level S), plus many
	&#8220;Extended&#8221; (level E) functions. The definitive
	reference on &micro;ITRON is Dr. Sakamura&#8217;s book:
	  <I
CLASS="CITETITLE"
>&micro;ITRON 3.0, An Open and Portable Real-Time Operating
	  System for Embedded Systems</I
>. 
	The book can be purchased from the IEEE Press, and
	an ASCII version of the standard can be found online at
