The Lightweight TrustZone-assisted Hypervisor (LTZVisor) allows multiple operating systems to run in the same hardware platform. LTZVisor uses the ARM TrustZone technology to guarantee robust isolation between components with different levels of criticality consolidated on the same hardware platform. TrustZone virtualizes the physical core as two virtual cores, providing two completely separate execution domains: secure and non-secure (normal) world. The non-secure world acts as a virtual machine (VM) under the control of a hypervisor running in the secure world side.  

TrustZone technology is specified by ARM and implemented by platform vendors. The specification has some components that are "implementation-specific", which means the TrustZone implementation changes from vendor to vendor, and can impose some challenges and issues when porting a TrustZone-assisted framework for a different platform., this project aims to port LTZVisor to the i.MX 6Quad SABRE board as well as extending the existent asymmetric multiprocessing (AMP) solution for supporting a quad-core configuration.
