Xilinx® provides multiple frameworks to facilitate application development on Versal ACAP as follows:
- Hypervisor Framework
- Xilinx supports the Xen hypervisor, a critical item needed to support virtualization on the Versal ACAP. For details, refer to Use of Hypervisors.
- Security Framework
- The Versal device supports authentication, encryption, and other cryptographic features as a part of the security framework. To understand more about the security framework, see the Security chapter.
- TrustZone Framework
- TrustZone technology allows and maintains isolation between secure and
non-secure hardware and software within the same system.
Xilinx provides TrustZone support through the Arm® trusted firmware (ATF) to maintain isolation between secure and non-secure worlds. If implementing a trusted execution environment (TEE) on a Versal device, ATF is one of the major components of a TEE. See this whitepaper for an overview of a TEE architecture.
- Multiprocessor Communication Framework
- Xilinx provides the OpenAMP framework for the Versal device to allow communication between the different processing units.
- Power Management Framework
- The power management framework allows software components running across different processing units to communicate with the power management unit.
