“…The OS and Application layers are implemented on the Application Processing Unit, which has a dual-core Cortex-A9. Since the selected MPSoC-FPGA has no isolation mechanism, we have used Protection Units (PUs) IP cores, as proposed in our previous work [46]. These PUs provide isolation support between PS-PL and PL-PL communication for MPSoC-FPGAs of the AMD-Xilinx series 7 family.…”

“…For safety issues, the various units responsible for different components are isolated through the Protection Unit proposed by authors in Ref. [46]. In fact, with the proposed solution, the slave-client nodes, such as the DMS, X-ray tube, and the HV module, must only implement the FSMs required for controlling the internal modules and setting them for the safe mode.…”

Cyber-Physical Systems (CPSs) combine computation, networking, and physical processes. A CPS consists of various independent subsystem components with different interfaces and protocols defined by vendors. Utilizing different interfaces and protocols with the necessity for flexible, dependable, and extensible CPSs poses new challenges for controlling, communicating, and synchronizing the components. In this paper, we propose a Centralized Control Unit (CCU) for CPSs and the associated Communication Infrastructure that enable the support of subsystem components as "plug-and-play" modules. Our CCU consists of a hardware-software architecture that handles physical signals as well as real-time and non-real-time tasks implemented on a single MPSoC-FPGA. To enforce the dependability and flexibility of the communication between components of different vendors, we model the Communication Infrastructure in layers with communication classes. In addition, we propose three vendor-agnostic application protocols, which are also implemented in the CCU. To validate our work, we have implemented and integrated the CCU with the communication infrastructure into an open-interface Computed Tomography (CT) scanner, where sensors/actuators can be added in a "plug-and-play" fashion. We have also evaluated the effort of integrating an additional detector into our scanner. The CCU runs on an AMD-Xilinx Zynq-7000 XC7Z045, and it uses only 10% of the hardware resources.
