ABSTRACT
The interaction of a cyber-physical system (CPS) may impose additional constraints upon cyber aspects of the system. For instance, sensing and actuation often require nonpreemption to ensure "accuracy" in data acquisition (e.g., radar sensors in automotive a cruise control system). Furthermore, CPS may require that a system adapts to changing environment which requires support for multiple operating modes. A multimode CPS may also enable resource-efficient solution by providing shared processing platforms to subsystems. Recent development [1] of multi-modal fixed-priority schedulability with non-preemption can facilitate multi-modal CPS-based design. In this demo, we present the benefits of such design choices by devloping a simple automotive adaptive cruise control (ACC) system using System objectsTM and Phased Array System ToolboxTM, which provides state-of-the-art tools for radar simulation. The ACC application composes tasks for radar transmission, reception, and controller upon a single processing platform. We consider radar transmission and signalreceiving tasks to have non-preemptible execution regions.
