The specification addressesfeatures which are common to the majority of processor architectures anddeliberately avoids virtualization which would adversely impactreal-time performance. The µITRON specificationmay be implemented on many hardware platforms and provides significantadvantages by reducing the effort involved in understanding andporting application software to new processor architectures. </P><P>Several revisions of the µITRON specification exist. In this release, <SPANCLASS="emphasis"><ICLASS="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: <ICLASS="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<AHREF="http://www.itron.gr.jp/"TARGET="_top">http://www.itron.gr.jp/</A>.The old address <AHREF="http://tron.um.u-tokyo.ac.jp/TRON/ITRON/"TARGET="_top">http://tron.um.u-tokyo.ac.jp/TRON/ITRON/</A>still exists as a mirror site. </P></DIV></DIV><DIVCLASS="NAVFOOTER"><HRALIGN="LEFT"WIDTH="100%"><TABLESUMMARY="Footer navigation table"WIDTH="100%"BORDER="0"CELLPADDING="0"CELLSPACING="0"><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top"><AHREF="compat-uitron.html"ACCESSKEY="P">Prev</A></TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="ecos-ref.html"ACCESSKEY="H">Home</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top"><AHREF="compat-uitron-over-ecos.html"ACCESSKEY="N">Next</A></TD></TR><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top">µITRON</TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="compat-uitron.html"ACCESSKEY="U">Up</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top">µITRON and <SPANCLASS="emphasis"><ICLASS="EMPHASIS">eCos</I></SPAN></TD></TR></TABLE></DIV></BODY></HTML>⌨️ 快捷键说明
