Solar blind detectors based on AlGaN heterostructures grown on sapphire by Molecular Beam Epitaxy and with a dielectric interference filter deposited on the back side are demonstrated to provide record spectral selectivity. Rejection ratios of 2 x 10(4), a ...
Networks-on-Chip are emerging as a widely accepted alternative for the traditional bus architectures. However, their applicability by the system designers is far away from being intuitive due to their lack of predictability. This communication predictabili ...
While the Global Positioning System (GPS) is best known for its positioning applications, another way to use GPS is as a time reference for telecommunication networks synchronization. However, as every new communication standard is more demanding, the prec ...
One of the biggest challenges that are facing the Very Large Scale Integrated Circuits (VLSI) technologies today is the significant performance gap (3× to 9×) between full custom circuits and Application Specific Integrated Circuits (ASICs) designed in the ...
The LHCb experiment is one of the four large particle detectors currently under construction at the LHC accelerator at CERN. It is a forward single-arm spectrometer dedicated to precision measurements of CP violation and rare decays in the b quark sector. ...
Software Distributed Shared Memory (DSM) systems based on virtual memory techniques traditionally use the hardware page as the consistency unit. The large size of the hardware page is considered to be a performance bottleneck because of the implied false s ...
Multimedia interfaces increase the need for large image databases, capable of storing and reading streams of data with strict synchronicity and isochronicity requirements. In order to fulfill these requirements, the authors consider a parallel image server ...
Loosely coupled multiprocessor systems communicate by message passing. Traditional implementations of message passing architectures are based on communication controllers accessing local memory through DMA channels. The authors describe a completely new co ...
