To get efficient HW management in 2D Reconfigurable Systems, heuristics are needed to select the best place to locate each arriving task. We propose a technique that locates the task next to the borders of the free area for as many cycles as possible, trying to minimize the area fragmentation. Moreover, we combine it with a look-ahead heuristic that allows(More)
Hyperspectral imaging is a new emerging technology in remote sensing which generates hundreds of images, at different wavelength channels, for the same area on the surface of the Earth. Over the last years, many algorithms have been developed with the purpose of finding endmembers, assumed to be pure spectral signatures in remotely sensed hyperspectral data(More)

This research work presents a novel proposal to get hardware multitasking in 3D FPGAs. Such architectures are still academic, but recent advances in 3D IC technologies allow foreseeing true 3D FPGAs in the near future. Starting from models for the 3D FPGA and for the tasks, an efficient technique for managing the 3D reconfigurable resources is proposed.(More)
Due to the emergence of highly dynamic multimedia applications there is a need for flexible platforms and run-time scheduling support for embedded systems. Dynamic Reconfigurable Hardware (DRHW) is a promising candidate to provide this flexibility but, currently, not sufficient run-time scheduling support to deal with the run-time reconfigurations exists.(More)
Dynamically Reconfigurable Hardware (DRHW) platforms present both flexibility and high performance. Hence, they can tackle the demanding requirements of current dynamic multimedia applications, especially for embedded systems where it is not affordable to include specific HW support for all the applications. However, DRHW reconfiguration latency represents(More)
—Hyperspectral remote sensing attempts to identify features in the surface of the Earth using sensors that generally provide large amounts of data. The data are usually collected by a satellite or an airborne instrument and sent to a ground station that processes it. The main bottleneck of this approach is the (often reduced) bandwidth connection between(More)
