+>The µITRON 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 µITRON 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 µITRON specification exist.
+ In this release, <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>eCos</I
+></SPAN
+> supports the
+ µITRON version 3.02 specification, with complete
+ “Standard functionality” (level S), plus many
+ “Extended” (level E) functions. The definitive
+ reference on µITRON is Dr. Sakamura’s book:
+ <I
+CLASS="CITETITLE"
+>µITRON 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
