It helps to split the embedded application various projects which creates the need to partition system resources. And it simplifies the consistent configuration of access rights across the system, for example when using an MPU (memory protection unit).</p> -<p>The following section describes several uses cases that benefit from <b>CMSIS-Zone</b>.</p> -<h2><a class="anchor" id="UseCase_MPU"></a> -MPU Protection</h2> -<p>Focused on a single core microcontroller one might want to utilize the memory protection unit (MPU) capabilities to segregate parts of an application. Thus the need to partition the system resources accordingly arises.</p> -<div class="image"> -<img src="mpu.png" alt="mpu.png"/> -<div class="caption"> -MPU Protection</div></div> - <h2><a class="anchor" id="UseCase_TrustZone"></a> -TrustZone Partitioning</h2> -<p>TrustZone extensions add another degree of segregation which must be handled consistently. In this case one has to handle MPU settings per security context and SAU configuration.</p> +<p>The following SoC diagram exemplifies step 1 and step 2 of this workflow.</p> <div class="image"> -<img src="trustzone.png" alt="trustzone.png"/> +<img src="Partitioning_Hardware.png" alt="Partitioning_Hardware.png"/> <div class="caption"> -TrustZone Partitioning and MPU Protection</div></div> - <h2><a class="anchor" id="UseCase_MultiCore"></a> -Multi-Core Partitioning</h2> -<p>Beside traditional single cores asymetric and hybrid multi-core devices contribute to increasing development complexity for embedded systems.
