<div class="textblock"><p><b>CMSIS-Zone</b> defines methods to describe system resources and to partition these resources into multiple projects and execution areas. The system resources may include multiple processors, memory areas, peripherals and related interrupts. The system resources and partition assignments are stored in <a class="el" href="zoneFormat.html">Zone Description Format</a> (XML based).</p>
<p><b>CMSIS-Zone</b> includes a utility that manages these XML files. This utility:</p>
<ul>
<li>displays all available system resources including memory and peripherals</li>
<li>allows to partition memory and assign resources to sub-systems.</li>
<li>supports the setup of secure, non-secure, and MPU protected execution zones with assignment of memory, peripherals, and interrupts.</li>
<li>provides a data model for generation of configuration files for tool and hardware setup.</li>
</ul>
<p>The following diagram explains the development work flow when using the <b>CMSIS-Zone</b> management tool.</p>
<div class="image">
<img src="Partitioning_Workflow.png" alt="Partitioning_Workflow.png"/>
<div class="caption">
CMSIS-Zone development workflow</div></div>
<p> The CMSIS-Zone utility reads a <a class="el" href="zoneFormat.html#rzone">.rzone</a> file that defines the overall system resources of an SoC system. An interactive GUI supports the system partitioning. The assignments of the various partitions (also called zones) saved in the <a class="el" href="zoneFormat.html#azone">.azone</a> file.</p>
<p>The combined information of resources and assignments can be exported to multiple <a class="el" href="zoneFormat.html#rzone">.rzone</a> files that represent a sub-system. By using file templates the CMSIS-Zone utility can create tool or hardware configuration files.</p>
<p>It is possible to uses these steps multiple times which allows to split a complex SoC design with multiple processors into smaller sub-systems. For example a multi-core device can be partitioned in steps:</p>
<ul>
<li>Step 1: split the multi-processor system into single processor sub-systems.</li>
<li>Step 2: create the partitions for secure and non-secure execution.</li>
<li>Step 3: configure MPU protected execution zones.</li>
</ul>
<p>The following SoC diagram exemplifies step 1 and step 2 of this workflow.</p>
