Actually multi-core processors designs are limited in power consumption and performance. Consequently, it is not possible to optimize further the performance without increasing power consumption. The main challenge in multi-core processors is the fact that they have heterogeneous hardware components. This article will study different technologies for implementing multi-core processors in FPGA devices. The minimum requirement to ensure low power consumption is parallelism. The purpose of this study is to highlight the latest methodologies used in terms of environment, clock signal, testing, flexibility, cost, availability and power consumption.

In everyday life the production and broadcast of material goods, computer and management in global communication cannot be realized without an electrical power source, the output of which is associated with environmental and safety problems. Current methods for providing electricity departing from limited natural resources, such as oil, gas, coal, etc. Simultaneously every day we face not only with the increasing prices for them, but also the problem of environmental pollution, which brings their burning. Fortunately there is a solution, and it is the use of renewable energy sources, such as biomass, solar energy, wind power, etc. Because of the benefits obtained from their use on dozens of regions in the world are directed to the use of these resources, especially solar energy. This energy is collected through solar panels and back into thermal or electric energy. Systems that convert the energy of sunlight into electricity are called photovoltaic systems. In this paper we will focus on the structuring of data collection about technologies and parameters to use photovoltaic systems in Albania. In order that these data collected be managed with high efficiency, it is appropriate that they are stored in a DB. DB Design brings genuine analysis of the current situation, but the future forecast for our country can be done on its basis. So on the basis of the studying of the DB, can be judge the economic and ecological benefits that come from the use of solar energy. The consumer can judge the energy efficiency, technology used, methods of installation, etc. Responsible institutions can deal with completing the updates of data for the completion of a DB at the national level.
