The Internet of Things (IoT) has moved beyond the hype, with promising applications materializing and industries transforming through digitalization as well as servitization—that is, delivering a service as an integral part of a product. Since the application spread in today’s IoT is wide and is typically structured in market-oriented groups, a system designer needs IoT system design patterns to assist...
By enabling diverse and large-scale transducers, large-area electronics raises the potential for electronic systems to interact much more extensively with the physical world than is possible today. This can substantially expand the scope of applications, both in number and in value. But first, translation into applications requires a base of system functions (instrumentation, computation, power management,...
The Cyber-Physical Energy Systems (CPES) represent a new class of widely distributed and globally interconnected energy systems that integrate computation processes, communication processes and control processes. The architecture design and verification in a CPES development is a key works. In this paper, a new CPES application architecture is proposed based on the features of energy systems, such...
This paper presents the State-of-the-Art and recent trends of SCADA system Architecture, which is usually three-layer SCADA system architecture depending on open system technology rather than a vendor controlled, proprietary technology. A Real-time Industrial process is simulated (boiling system), and a complete three-layer model SCADA system is developed for this process, supervision control layer,...
This paper presents a multiagent architecture applied to factory automation. These agents detect faults in process automation and allocate intelligent algorithms in field device function blocks to solve these faults. It is also present a dynamic function block parameter exchange strategy which allows agent fieldbus allocation. The objective is to enable problem detection activities independent of...
The purpose of TAFT fault tolerance studies conducted at CNES is to prepare the space community for the significant evolution linked to the usage of COTS components for developing spacecraft supercomputers. CNES has patented the DMT and DT2 fault-tolerant architectures with 'light' features. The development of a DMT/DT2 testbench based on a PowerPC7448 microprocessor from e2v is presented in this...
Multi-core SoC created great opportunities to increase overall system performance while keeping the power in check but also created many design challenges that designers must now overcome. The challenge of doubling performance every two years used to drive superscalar design with more functional units running concurrently or deeper pipeline racing for highest frequency at the cost of higher power...
A high bandwidth critical path monitor (1 sample/ cycle at 4-5 GHz) capable of providing real-time timing margin information to a variable voltage/frequency scaling control loop is described. The critical path monitor tracks the critical path delay to within 1 FO2 inverter delay with a standard deviation less than 3 FO2 delays over process, voltage, temperature, and workload. The CPM is sensitive...
