FPGA Implementation of JPEG and JPEG2000-Based Dynamic Partial Reconfiguration on SOC for Remote Sensing Satellite On-Board Processing
This paper presents the design procedure and implementation results of a proposed hardware which performs different satellite Image compressions using FPGA Xilinx board. First, the method is described and then VHDL code is written and synthesized by ISE software of Xilinx Company. The results show that it is easy and useful to design, develop and implement the hardware image compressor using ne...
متن کاملOptimal Reconfiguration of Solar Photovoltaic Arrays Using a Fast Parallelized Particle Swarm Optimization in Confront of Partial Shading
Partial shading reduces the power output of solar modules, generates several peak points in P-V and I-V curves and shortens the expected life cycle of inverters and solar panels. Electrical array reconfiguration of PV arrays that is based on changing the electrical connections with switching devices, can be used as a practical solution to prevent such problems. Valuable studies have been perfor...

متن کاملDynamic Reconfiguration in a GNSS Software Defined Radio for Multi-Constellation Operation
Recent advances in the US GPS constellation have resulted in additional signals being made available for both military and civil applications. The modernized GPS signal structure now includes signals broadcast on three frequencies with both the legacy GPS modulation codes, additional civilian codes, and also additional military codes on L1 and L2. In the next few years, GNSS users will also be ...
متن کاملDesign of a Reconfigurable Platform for Navigation Signal Simulation
Navigation signal simulator can generate signals consistent with real GNSS (Global Navigation Satellite System) signals, which can be processed by GNSS receivers in the same manner as it processes satellite signals in a real testing environment. The simulator can offer a high-fidelity means of testing GNSS receivers and other related systems. Such tests can be carried out in laboratories due to...
