Dynamic partial reconfiguration (DPR) allows us to adapt hardware resources to meet time-varying requirements in power, resources, or performance. In this paper, we present two new DPR systems that allow for efficient implementations of 1D FIR filters on modern FPGA devices. To minimize the required partial reconfiguration region (PRR), both implementations are based on distributed arithmetic. ...

Evolvable hardware combines the powerful search capability of evolutionary algorithms with the flexibility of reprogrammable devices, thereby providing a natural framework for reconfiguration. This framework has generated an interest in using evolvable hardware for fault-tolerant systems because reconfiguration can effectively deal with hardware faults whenever it is impossible to provide spare...

Dynamic reconfiguration increases the availability of distributed applications by allowing them to evolve at run-time. This report deals with the formal specification and model-checking verification of a dynamic reconfiguration protocol used in industrial agent-based applications. Starting from a reference implementation in Java, we produced a specification of the protocol using the Formal Desc...

In this paper we discuss different aspects of system reconfiguration and their relation to the specific requirements from the application domain. Two projects – one from the video processing the other one from the IP networking domain – are introduced that make different use of runtime reconfiguration by either changing individual processing units or the logical interconnect structure of the sy...

 Abstract—Dynamic reconfiguration is essential part of software evolution. Several approaches to support dynamic reconfiguration have been proposed in the literature. These approaches are different in various criteria. The goal of this work is to make a comparative study between various dynamic reconfiguration approaches by exploring the features of these approaches and to classify them with r...

Open and dynamic characteristics of distributed software systems make user requirements and hardware resources change more rapidly, which make their evolution or reconfiguration inevitable, especially during their execution. A critical issue for those distributed systems is the specifying and analysis dynamic reconfiguration process of their architectures. In this paper, we proposed a method of...
