Title: Towards Efficient Real-Time Embedded Cyber-Physical Systems
Abstract:
Embedded systems are computer systems designed for specific control functions within larger systems, often with real-time constraints --- e.g., deadline requirements. Real-time embedded systems are pervasive often without being noticed. Such systems range from portable devices such as smartphones, to large stationary installations like traffic lights, to systems controlling nuclear power plants. The demand for embedded systems is expected to expand fast in the near future. By 2015, more than 4 billion units of embedded devices will be shipped, which will create 2 trillion in revenue. Much of this growth is currently being propelled by the emerging trend of building more sophisticated and intelligent cyber-physical systems (CPSs), which often integrate and coordinate multiple networked computational and physical elements. Many CPSs have multiple dependent networked components, each implementing a specific functionality. Moreover, CPS are expected to actively interact with environment, human beings, and other external devices. These properties often result in complex inter- and/or intra-component dependencies. Unfortunately, existing research on real-time embedded systems has been limited to simple systems for which dependencies do not exist; this limits the practical applicability of such research. In practice, dependencies are currently dealt with by over-provisioning systems, which is an economically wasteful practice. In this talk, I will present predictable multicore real-time embedded system design, analysis, and implementation methods that enable sophisticated multicore-based CPSs that contain common types of dependencies to be efficiently designed and built. I will show that the proposed methods are able to avoid over-provisioning systems and to reduce the number of needed hardware components to the extent possible while providing timing correctness guarantees.
