<h1><a id="general-description" name="general-description">General Description</a></h1>
<p>A port is target-specific implementation of the RTOS. Port contains a number of
definitions and declarations that reflect target processor and cross-compiler
features. Any port consists of two parts:</p>
<ul class="simple">
<li>Common part;</li>
<li>Target-specific part;</li>
</ul>
<p>Any official Release, Sample or user project that uses the RTOS includes these
two parts and <a class="reference" href="../releases/index.html">project-dependent</a> part also.</p>
<div class="section">
<h2><a id="common-part" name="common-part">Common Part</a></h2>
<p>Common part contains main RTOS definitions and declarations such as RTOS kernel,
interprocess communication services and little support library. All Common sources
stand at <tt class="docutils literal"><span class="pre">Common</span></tt> subfolder.</p>
</div>
<div class="section">
<h2><a id="target-specific-part" name="target-specific-part">Target-specific Part</a></h2>
<p>Target-specific part describes target processor-specific and toolkit-dependent
features  of the RTOS:</p>
<ul class="simple">
<li>Target-level configuration macros;</li>
<li>Critical section definition;</li>
<li>Some performance-critical functions;</li>
<li>Interrupt and interrupt service routines support;</li>
<li>Target processor specific process's constructor;</li>
<li>Idle process declaration.</li>
</ul>
<p>Target-specific sources located at <tt class="docutils literal"><span class="pre">&lt;PortName&gt;</span></tt> subfolder where <em>PortName</em>  descends
from target processor and cross-compiler names.</p>
<p>Subfolders <tt class="docutils literal"><span class="pre">Common</span></tt> and <tt class="docutils literal"><span class="pre">&lt;PortName&gt;</span></tt> are placed to folder <tt class="docutils literal"><span class="pre">scmRTOS</span></tt> <a class="footnote-reference" href="#id5" id="id2" name="id2">[1]</a>.</p>
