Reference system using TrustZone for Armv8-M
The subsystem architecture at the heart of the Musca-A1 test chip, is used by all the ecosystem surrounding the new Armv8-M processors. It expands the Arm TrustZone isolation outside of the processor, throughout the system.
Dual asymmetric Cortex-M33 for performance/power dynamic tuning
Having a fast processor active all the time is not efficient for power consumption. The flexible processing architecture of the subsystem at the heart of the Musca-A1 test chip allows a great level of flexibility. It ensures that performance is available when you need it, but doesn’t consume energy when you don’t need it.
Embedded security with TrustZone CryptoCell
Isolation is the secret to get secure systems. In addition to a Root-of-Trust, the Arm TrustZone CryptoCell IP brings an additional level of security for key handling, lifecycle management, encryption, authentication and many other crypto services.
