In this paper, we thoroughly consider the technique of conversion of procedural programs in C to configuration files for field-programmable gate arrays used in the toolkit for programming of reconfigurable and hybrid computer systems. The creation of parallel program in the COLAMO (Common Oriented Language for Architecture of Multi Objects) language using the analysis results of information dependences in the initial procedural program and its further conversion to a parallel and pipeline form are the distinctive characteristics of the technique. We addressed the methods of scalar splitting and array extension by iterations, which are applied for the fulfillment of the single assignment and unique substitution rules in parallel program and the saving of information communications of the initial procedural program. The technique of conversion of automatically created parallel program to the scalable parallel and pipeline form is presented. The “Procrustes” preprocessor adapts the form for different architectures and configurations of reconfigurable and hybrid computer systems. Owing to the described methodology, it is possible to synthesize a resource-independent scalable COLAMO-application, which can adapt to available computational resource by changing of several constants in automatic mode without any considerable modification of the program source code. Then, the scalable COLAMO-applicationis translated by the COLAMO-translator into field-programmable gate arrays configuration files for the specified reconfigurable computer resource.

In this article, we consider the stages of development of a novel application toolkit for reconfigurable computer systems, its architecture and operation principles. The toolkit provides the translation of procedural programs in C to configuration files for field-programmable gate arrays in 6 stages. The conversion of procedural program in C to parallel program in COLAMO (Common Oriental Language for Architecture of Multi Objects) is performed using four additional programs: the “Angel ” translator and three preprocessors called the “Mermaid ”, the “Procrustes” and the “Nutcracker ”. At the first stage, the “Angel ” translates the C program into the absolutely parallel program in the COLAMO language. During the second stage, the information dependences of the initial C program are analyzed, scalar variables are split, and arrays are stretched by iterations. Then, at the third stage, the COLAMO code is converted to the parallel and pipeline form using the partition of arrays and loops into the vector and strea components. The fourth stage involves the transformation of the COLAMO program to the scalable parallel and pipeline form. The optional fifth stage, which is aimed at the reduction of the base subgraph, is executed only in the case of the lack of hardware resource for the structural implementation of the base subgraph of a problem. At the sixth stage, the COLAMO program is transformed to the unique computational structure and several cadrs designed for the architecture of the chosen reconfigurable computer system. The distinctive feature of the developed toolkit is the support of the resource-independent computing, which allows for the scaling of calculations in both cases of increase (induction) and decrease (reduction) in available hardware resources.

The development and optimization of a hybrid system composed of photovoltaic panels, wind turbines, converters, and batteries connected to the grid, is first presented. To generate the maximum power, two maximum power point tracker controllers based on fuzzy logic are required and a battery controller is used for the regulation of the DC voltage. When the power source varies, a high-voltage supply is incorporated (high gain DC-DC converter controlled by fuzzy logic) to boost the 24 V provided by the DC bus to the inverter voltage of about 400 V and to reduce energy losses to maximize the system performance. The inverter and the LCL filter allow for the integration of this hybrid system with AC loads and the grid. Moreover, a hardware solution for the field programmable gate arrays-based implementation of the controllers is proposed. The combination of these controllers was synthesized using the Integrated Synthesis Environment Design Suite software (Version: 14.7, City: Tunis, Country: Tunisia) and was successfully implemented on Field Programmable Gate Arrays Spartan 3E. The innovative design provides a suitable architecture based on power converters and control strategies that are dedicated to the proposed hybrid system to ensure system reliability. This implementation can provide a high level of flexibility that can facilitate the upgrade of a control system by simply updating or modifying the proposed algorithm running on the field programmable gate arrays board. The simulation results, using Matlab/Simulink (Version: 2016b, City: Tunis, Country: Tunisia, verify the efficiency of the proposed solution when the environmental conditions change. This study focused on the development and optimization of an electrical system control strategy to manage the produced energy and to coordinate the performance of the hybrid energy system. The paper proposes a combined photovoltaic and wind energy system, supported by a battery acting as an energy storage system. In addition, a bi-directional converter charges/discharges the battery, while a high-voltage gain converter connects them to the DC bus. The use of a battery is useful to compensate for the mismatch between the power demanded by the load and the power generated by the hybrid energy systems. The proposed field programmable gate arrays (FPGA)-based controllers ensure a fast time response by making control executable in real time.
