><P
>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
