Tornado facilities execute primarily on a host system, with shared access to a host-based dynamic linker and symbol table for a remote target system. <a href="c-overview1.html#85690">Figure 1-1</a> illustrates the relationships between the principal interactive host components of Tornado and the target system. Communication between the host tools and VxWorks is mediated by the target server and target agent (<a href="c-overview1.html#85690">Figure 1-1</a>). <div class="frame"><h4 class="EntityTitle"><a name="85690"><font face="Helvetica, sans-serif" size="-1" class="sans">Figure 1-1: Tornado Development Environment</font></a></h4><dl class="margin"><div class="Anchor"><a name="85740"> </a><img class="figure" border="0" src="images/c-overviewa.gif"></div></dl></div></p><dd><p class="Body"><a name="83934"> </a>With Tornado, the cycle between developing an idea and the opportunity to observe its implementation is extremely short.
