This paper describes a supervision system for photovoltaic power plants. Data from devices of photovoltaic plant are collected and analyzed monitoring the plant behavior. The supervision system can control the device varying their functionality. It integrates different features which are usually demanded to single separated subsystems and specific functionality devoted to the security of the installations...
This paper focuses on the optimization process of the HEVC/H.265 video decoder on suitable architectures for mobile devices. The solutions developed to support the new HEVC/H.265 features are shown together with the achieved performance. The HEVC/H.265 decoder complexity has been evaluated and the most demanding modules have been optimized with Single Instruction Multiple Data (SIMD) instructions...
In this paper an optimized implementation of the HEVC video decoder is shown. The solutions developed to support the new features of HEVC are shown together with the achieved performance. The HEVC decoder complexity has been evaluated and the most demanding modules have been optimized exploiting SIMD instructions. Even though the here described concepts have a general value, the effectiveness of the...
In this paper an efficient FPGA implementation of a packet pre-filtering algorithm based on Bloom filter is presented. In high speed link the traffic classification involves a very large amount of data per each packet processed (header and payload analysis). This leads to use hardware with high computational power and very expensive, in order to support requirement of real-time classification. Our...
This paper describes a supervision system able to handling the data collection from photovoltaic implants, their analysis allowing providing prevision and control of energy production. The supervision system integrates different functionality usually demanded to single subsystems and advanced features devoted to the implants maintenance and security. The supervision system is able to interact with...
In this paper a single phase inverter grid connected implementation is presented. The proposed solution is based on the calculation of the input line fundamental harmonic using a DSP processor. Our aim is to increase the inverter performance through a better synchronization with the grid and achieving a unitary power factor even in case of distorted input line, usually present in industrial environments...
In this paper, the implementation of a DSP controlled ac-dc matrix converter is presented. A Phase Locked Loop is used to synchronize the high frequency ac voltage synthesized by the matrix converter with the three phase input line. This solution allows obtaining a stable output dc voltage even in case of non ideal input phases, which is the typical actual input in an industrial environment. Experimental...
