This paper analyzes the errors entailed by the signal amplitude inequality when measuring the phase shift among low frequency harmonic signals for algorithmic sum-difference methods. It is shown that additional phase shifts of summary and difference signals caused by the inequality of compared signals in some methods affect the errors, whereas in others they do not. A method in which there is no additive component of the error has been found. This method has been admitted to be the best to measure small phase shifts. The method for measuring the phase shift, which enables to avoid errors due to amplitude inequality of compared signals has been proposed.

The FPGA-based accelerators and reconfigurable computer systems based on them require designing the application-specific processor soft-cores and are effective for certain classes of problems only, for which application-specific processor soft-cores were previously developed. In Self-Configurable FPGA-based Computer Systems the problem of designing the application-specific processor soft-cores is solved with use of the C2HDL tools, allowing them to be generated automatically. In this paper, we study the questions of the self-configurable computer systems efficiency increasing with use of the partially reconfigurable FPGAs and Chameleon C2HDL design tool. One of the features of the Chameleon C2HDL design tool is its ability to generate a number of application-specific processor soft-cores executing the same algorithm that differ by the amount of FPGA resources required for their implementation. If the self-configurable computer systems are based on partially reconfigurable FPGAs, this feature allows them to acquire in every moment of its operation such a configuration that will provide an optimal use of its reconfigurable logic at a given level of hardware multitasking.

Computer systems performance is today improved with two major approaches: general-purpose computer computing power increase (creation of multicore processors, multiprocessor computer systems, supercomputers), and adaptation of the computer hardware to the executed algorithm (class of algorithms). The last approach often provides application of hardware accelerators - ASIC-based and FPGA-based, also named reconfigurable, and is characterized by better performance/power consumption ratio and lower cost as compared to the general-purpose computers of equivalent performance. However, such systems have typical problems. The ASIC-based accelerators: 1) they are effective only for certain classes of algorithms; 2) for effective application there is a need to adapt algorithms and software. The FPGA-based accelerators and reconfigurable computer systems (that use FPGAs as a processing units): 1) the need in the process of writing a program to perform computing tasks balancing among the general-purpose computer and FPGA; 2) the need of designing application-specific processors soft-cores; and 3) they are effective only for certain classes of problems, for which application-specific processors soft-cores were previously developed. This paper covers the scope of questions regarding concept of design, architecture, and proof of concept of the Self-Configurable FPGA-Based Computer Systems - an emerging type of high-performance computer systems, which are deprived of specified challenges. The method of information processing in reconfigurable computer systems and its improvements that allow an information processing efficiency to increase are shown. These improvements are used as a base for creating a new type of high-performance computer systems with reconfigurable logic, which are named self-configurable ones, and a new method of information processing in these systems. The structure of self-configurable FPGA-based computer system, the rules of application of computer software and hardware means necessary for these systems implementation are described. Major processes on the stages of program loading and execution in the self-configurable computer system are studied, and their durational characteristics are determined. On the basis of these characteristics, the expressions for evaluating the program execution duration in the self-configurable computer system are obtained. The directions for further works are discussed.

In these article the mathematical model of multi-agent CFS is proposed for describe of behavior of moving objects, interacting under wireless communication link on 802.11 standard. It has shown that the more important criteria for CFS, consisting of mobile objects, is the stability of communications. The stable transmission rate is achieved by reducing the asymmetry of the link between the cyber-physical components. This will ensure the rhythmical loading of the computing board processors (CPU or/and GPU) on cyber object. The models of camera's matrices and computing boards for unmanned vehicles (UMV) are analyzed and proposed. The methods of avoidance the dropping of rate due to interference from the connecting to the ether of new access points, non-containing to CFS, are presented. The research and results contributes to the improving quality of transmission and processing data from wireless cyber-physical components.

Measurement of RLC-parameters of objects non-electric nature (for example, biological, agricultural, environmental, etc.) with high metrological characteristics is an essential element for building a cyber-physical systems analytical purposes. The reliability of the measurement results of the equipment can be provided only by periodic metrological control over the exploitation conditions. Traditionally analytical RLC-meters are calibrated by means of standard samples and it leads to significant problems in their metrological assurance and complicates whole procedure.

Big data and high performance computing are seen by many as important tools that will be used to advance science. However, the computational power needed for this promise to materialize far exceeds what is currently available. This paper argues that the von Neumann computational model, the only model in everyday use, has inherent weaknesses that will prevent computers from achieving the envisaged performance levels. First, these weaknesses are explored and the properties of a computational model are identified that would be required to overcome these weaknesses. The performance benefits of implementing a model with these properties are discussed, making a case that a computational model with these properties has the potential to address the needs of high performance computing. Next, the paper presents a proposed computational model and argues that it is a viable alternative to the von Neumann model. The paper gives a simplified outline of an architecture and programming language that express the proposed computational model. The main feature of this computational model is that it processes variables as they become defined. These variables can be processed in any order and simultaneously, avoiding bottlenecks and enabling high levels of parallelism. Finally, the computational model is evaluated against the properties identified as desirable, showing that it is possible to design an architecture and programming language that do not have the weaknesses of the currently dominant von Neumann model. The paper concludes that the weaknesses which limit the performance of current computers can be overcome by exploring alternative computational models, architectures and programming languages, rather than by working towards incremental improvements to the existing dominant model.
