This thesis presents two families of novel waveguide-integrated components based on millimeter-wave microelectromechanical systems (MEMS) for reconfigurable systems. The first group comprises V-band (50–75 GHz) and W-band (75–110 GHz) waveguide switches and switchable irises, and their application as switchable cavity resonators, and tunable bandpass filters implemented by integration of novel ...

We are presenting a novel reconfigurable system architecture: the Strategically Programmable System (SPS). The motivation for such a system is the needs of today’s high flexibility, high performance computing. SPS contains versatile blocks embedded into fully reconfigurable logic. Dedicated blocks fixed on the chip perform the bulk of the computations; hence the reconfiguration time of the syst...

This paper presents recent work on reconfigurable all-digital radio architectures. We leverage the flexibility and scalability of synthesized digital cells to construct reconfigurable radio architectures that consume significantly less power than a software defined radio implementing similar architectures. We present two prototypes of such architectures that can receive and demodulate FM and FR...

As modern areas of application for coarse-grained reconfigurable systems digital signal processing, multimedia in embedded devices, and wireless communication can be mentioned among others. These fields include different algorithms with varying complexity and speed requirements. In this paper a new highly parameterizable coarse-grained reconfigurable architecture called weakly programmable proc...

ÐThe Linear Array with a Reconfigurable Pipelined Bus System (LARPBS) is a newly introduced parallel computational model, where processors are connected by a reconfigurable optical bus. In this paper, we show that the selection problem can be solved on the LARPBS model deterministically in O……log logN†= log log logN† time. To our best knowledge, this is the best deterministic selection algorith...

A new reconfigurable active router architecture is presented in this paper. It consists of a software part and a hardware part. The software part is a set of kernel-space and user-space modules running on a linux-PC. An FPGA PCI-based board with a Virtex-1600E FPGA forms the hardware part. The integration of reconfigurable hardware into standard PC hardware allows for on-the-fly reconfigurable ...

Efficient management of distributed resources, under conditions of unpredictable and varying workload, requires enforcement of dynamic resource management policies. Execution of such policies requires a relatively fine grain control over the resources allocated to jobs in the system. Although this is a difficult task using conventional job management and program execution models, reconfigurable...

The paper presents a new stochastic model for mesh-based reconfigurable computing. Under the conditions of several statistical assumptions, closed formulae of probability and mathematical expectation are derived for each type of connections. Both the theoretical deduction and simulation results are given to verify our approach. The elementary research can be applied to implement and optimize th...

In this work we present a survey of different papers about reconfigurable computing and its applications. These papers treat very different reconfigurable-computing applications: cryptography, computer vision, SOPC, microprocessor architecture, self-timed circuits, sensor systems, detection of ultrasonic emissions, FPGA compilation aspects (like data-dependent loops), and motion estimation. As ...

This dissertation focuses on the dynamic behavior of the reconfigurable architec-tures. We start with a survey of the existing work with the aim of categorizing the current research and identifying the future trends. The survey discusses the design issues of the reconfigurable architectures, the run-time management strategies and the design methodologies. The second part of our work focuses on ...
