A control system applying reconfigurable computers has been designed and built for the active alignment system of ATF at KEK. The system measures the relative position of accelerator components with a high precision allowing remote correction of the misalignments. A control system that acquires the data and permits the position control was developed. The system was built using reconfigurable lo...

New analytical and the speedup models for evaluating the performance of a generic reconfigurable coprocessor (RC) system are presented. We present a generic performance model for the speedup of a generic RC system. We demonstrate how different parameters of speedup model can affect the performance of reconfigurable system (RS). In addition, we implement our pre-developed speedup model for a sys...

The design, fabrication and measurement of a reconfigurable fishnet metamaterial based on a new method of tuning by changing unit cell geometry is reported. Retractable elements are added to the unit cell utilizing pneumatically actuated switching. It is shown that the pneumatic actuation approach can unite a number of metallic elements into a complex conducting structure. Experimental demonstr...

based on a fundamental unit that can perform at a very high level of abstraction a multi-level controller and sensor hub that is completely software reconfigurable, including basic and ancillary functionality. In this scheme, each unit can act as a single complex controller as part of a locally controlled mesh, which in turn can be part of a wider distributed or hierarchical control network. Al...

A novel reconfigurable membership function circuit (RMFC) for analog fuzzy logic controller (FLC) is presented. The reconfigurable characteristic makes it more suitable in industrial control applications when compared with the MFC proposed in [1]. By proper signal arrangement, the RMFC can re-sample the same input current in different configuration, which reduces the number of MFC in analog FLC...

We present a framework for real-time tracking of objects. Our system consists of multiple cameras and a control unit that communicate through a network. Each camera has a generalpurpose processor and a reconfigurable hardware unit embedded in it. Therefore, some computation can be performed at the point of data collection. We argue that collocating the computation with the data at vision sensor...

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 ...

Most existing techniques for reconfigurable processors focus on the computation model. This paper focuses on increasing the granularity of Efficient Energy Saving units without compromising flexibility. This is carried out by matching the granularity to the degree-of-freedom processing in most wireless Networks. A design flow that accelerates the exploration of tradeoffs among various architect...

An equivalent circuit approach is adopted in this paper to analyze a novel varactor loaded phasing line, specifically designed to improve the frequency agility features of reconfigurable aperture-coupled reflectarray cell, through the use of a couple of microstrip radial stubs. The proposed analysis method is fruitfully implemented to perform a fast and preliminary investigation on the improvem...

Coarse grained reconfigurable architecture (CGRA) has become an important solution for high performance computing because of its high speed up ratio for computation intensive applications, fast configuration, good adaptability and low power consumption. However, the traditional performance analysis method of register transfer level modeling is simulating, which is still widely used. To overcome...
