The electrical circuit modelling of a photovoltaic module and the implementation MPPT controller on Field Programmable Gate Array (FPGA) is investigated in this article. The maximum power point location is always unknown at any instant from the PV cells thus necessitate the design of locating this maximum point using some controller. The widely used P and O algorithm is implemented on FPGA system...
In this paper, we propose the FPGA implementation of a watermarking algorithm in the spatial domain. The paper put emphasis on Quantization Index Modulation based watermarking approach using dither sequences. The cost-effective data embedding algorithm can conceal watermark into original cover image coming from a sensor more rapidly than software implementation and the embedded image is effortlessly...
