Nowadays on latest Cortex-A9 processors, embedded system designers are enabled to use simultaneously multi O.S. instances for real time control and user interface on the same SOC. Two main concerns of this architecture are real-timeness and system integrity. This lecture describes how to meet those requirements by using ARM TrustZone technology. Performance tests are also detailed providing an overview on the solution reliability.
