Video: ARM TrustZone Video Application Note

For a demo of how easy it is to model and use ARM TrustZone in OVP platforms.There is also an Application Note that you can read that explains everything you see in this video.

This video has several sections. Its contents are listed after the image below. Click on the section links to view the video from the start of that section.
