Invasive Computing For Predictability Of Multiple Non-Functional Properties: A Cyber-Physical System Case Study

The predictability of non-functional execution qualities is of utmost importance for the successful introduction of multi-core architectures in embedded systems requiring guarantees rather than best effort behavior. Due to the exclusive utilization of claimed resources, invasive computing provides isolation of applications on multi-core systems. This provides composability that allows to characterize and analyze individual applications statically and independent from others. In this paper, we demonstrate the principles of this resource-aware computing paradigm as an enabler for predictability of multiple non-functional properties, i.e., timing and reliability, applied to a cyber-physical system. In particular, we present the application and multi-processor implementation of a reliable and time-predictable acceleration of object detection algorithms for hard real-time control of an inverted pendulum.
