<h1>On-Demand Paging<a class="headerlink" href="#on-demand-paging" title="Permalink to this heading"></a></h1>
<p>The NuttX On-Demand Paging feature permits embedded MCUs with some
limited RAM space to execute large programs from some non-random
access media. If the platform meets certain requirements, then
NuttX can provide on-demand paging: It can copy .text from the
large program in non-volatile media into RAM as needed to execute
a huge program from the small RAM. Design and porting issues for
this feature are discussed in a separate document. Please see the
<a class="reference internal" href="../../components/paging.html#ondemandpaging"><span class="std std-ref">NuttX Demand Paging</span></a> design document
for further information.</p>
