<dd><p class="Body"><a name="85622"> </a>The following example shows the configuration for a multiprocessor system with three CPUs. The master is CPU 0, and shared memory is configured from its dual-ported memory. This application has 20 tasks using shared-memory objects, and uses 12 message queues and 20 semaphores. The maximum size of the name database is the default value (100), and only one user-defined memory partition is required. On CPU 0, the shared-memory pool is configured to be on-board. This memory is allocated from the processor's system memory. On CPU 1 and CPU 2, the shared-memory pool is configured to be off-board. <a href="c-smo4.html#87285">Table&nbsp;6-6</a> shows the values set on the <b class="guiLabel"><font face="Helvetica, sans-serif" size="-1" class="sans">Params</font></b> tab of the properties window for <b class="symbol_UC">INCLUDE_SM_OBJECTS</b> in the project facility. <p class="table">
