This paper presents a novel reconfigurable control method for an aircraft with potential actuator failures. A Variable Structure Model Reference Adaptive Control (VSMRAC) scheme is deployed to counteract the adverse effects when the actuator failure occurs. Combined with exponential reaching law, the convergence rate is improved and the chattering is reduced. This approach ensures that the refe...

Software reconfigurability of air interfaces, the actual reconfiguration processes and the procurement of reconfiguration software are posing substantial threats to the system integrity of wireless communication system. These threats are investigated and reported in this paper and mechanisms to ensure secure reconfiguration procedures are described. The security mechanisms documented form part ...

In these days, many dynamically reconfigurable architectures have been introduced to fill the gap between ASICs and softwareprogrammed processors such as GPPs and DSPs. These reconfigurable architectures have shown to achieve higher performance compared to software-programmed processors. However, reconfigurable architectures suffer from a significant reconfiguration overhead and a speedup limit...

In FPGA-based control system design, partial reconfiguration is especially well suited to implement preemptive systems. In real-time systems, the deadline for critical task can compel the preemption of noncritical one. Besides, an asynchronous event can demand immediate attention and, then, force launching a reconfiguration process for high-priority task implementation. If the asynchronous even...

This paper examines the implementation of pipelined applications using run-time reconfiguration. Throughput and latency of pipelined applications can be significantly improved when reconfiguration is performed at the level of individual pipeline stages, as opposed to configuration of the entire FPGA. If reconfiguration and execution can be performed simultaneously, the performance of a pipeline...

— To prevent from topology changes, failures, or overloads, network management requires frequently computation and reconfiguration of established connections. When the number of established connections in the network is very large, the optimization of the reconfiguration task is essential to have short latency. When the communications using these connections are real-time, traffic interruption ...

Programmable networks allow third parties to reprogram networking devices. By opening up the execution environment of routers, firewalls, gateways, etc., users and service providers can adapt the behavior of these devices to meet their own specific needs. Programmable networks are therefore an interesting technology to build adaptive networks and to support the increasing evolution of networkin...

This report presents a configuration memory architecture that offers fast FPGA reconfiguration. The underlying principle behind the design is the use of fine-grained partial reconfiguration that allows significant configuration re-use while switching from one circuit to another. This technique makes use of existing on-chip configuration fragments in order to construct later circuits thereby red...

Dynamic reconfiguration to the changing environment is an essential aspect of ubiquitous mobile terminals. While striving towards reconfigurability in mobile devices, we must understand the technical constraints involved in reconfiguration. Variations in factors, such as, terminal size, memory, power usage, network coverage play a vital role in dynamic reconfiguration. With the proliferation of...
