Safe and Secure Heterogeneous Compute with L4Re
Today’s embedded systems cover an increasingly large set of functionality and features, consisting of multiple, different processors and subsystems. Those heterogeneous systems run different kinds of operating systems and hypervisors, making it a challenge to flexibly place applications across the whole platform. With L4Re, we abstract from the hardware and provide common interfaces for applications across different kinds of processors. Thereby we enable system integrators to design their system such that hardware as well as software components can be optimized for a given use-case. At the same time the common interfaces allow for rapid, near seamless adaptation when hardware or software requirements change. L4Re is being certified for both security and safety for use in security appliances, automotive and similar use-cases. This talk will present the challenges posed by providing common abstractions for modern heterogeneous architectures and will show how the L4Re Operating System Framework and Hypervisor addresses them.
