The subject of research is the problem of choosing the most efficient hardware architecture that implements the algorithm for deconvolution (recovery) of distorted images. The Wiener filter is taken as the deconvolution algorithm under consideration, due to its efficiency, both in terms of image restoration quality and due to acceptable time complexity. The object of study is the process of determining the time complexity of the considered algorithm for the recovery of damaged images when it is executed on a central processing unit (CPU) and a graphics processing unit (GPU). The main functions of blurring and defocusing of images are considered: Gaussian blur, Bokeh effect, Motion blur or motion blur. The research method is based on an experimental assessment of the dependencies of the algorithm operation time based on the Wiener filter, performed on the CPU and GPU, on the dimension of the image being restored. The results of a computational experiment conducted in order to compare the dependencies of the operating time of the Wiener filter, performed on the central processor and the graphic processor, on the size of the image being restored, are presented. Based on the presented results, it was found that when using images whose dimensions do not exceed 1920 * 1080, the Wiener filter is more expedient to implement on the CPU, and when restoring images that are larger than 1920 * 1080 - on the GPU.

The article proposes a concept system of connected together and arising from one another views on the creation and practical use of shore control center (SCC) by autonomous unmanned underwater vehicles (AUV). Within the framework of the above concept, the threats having the most significant impact on the AUV control, as well as the methods and means to counter these threats, are determined. The information passing and processing in a system for collecting, transmitting and displaying information (SCTDI) are considered as a parallel set of independent routes, information on which flows to the SCC AUV. In terms of the theory of flows and queuing systems (QS), in a dynamic sense, the system of collecting, transmitting and displaying information (SCTDI) deals with the composite flows, which are non-stationary in general, possibly with after-effect (correlation). Fines are in force at all levels of information collecting and transmitting and even imposed on a decision maker (DM) who makes a decision to use the AUV. Considered are the possible options for coordinating decisions developed by the SCC and AUV automated control systems, in which the decisions are made by the artificial intelligence created by man. The lower level consists of a collection, a series of convolutions and contractions, and finally, the Z-scene itself, messaging, situation, and just the situation is the subject of cognitive identification in the X-scene by the decision-making system. That is, the decision block includes an automated subsystem and a decision maker, which interact in a dialog mode.

The development of electrochemical impedance spectroscopy method in the field of high-frequency signals is proposed using an amplitude-phase approach to analyze the parameters of various biological sensors. Unlike the standard high-frequency analog electrochemical impedance spectroscopy systems interfaces based on quadrature demodulation, the use of peak and phase detectors allows improving the basic metrological parameters, as well as simplifying the analog interface with a wide bandwidth of the biological sensor interrogation signal. The circuit design of the phase detector, as part of the general system, is considered on the components of the technological process TSMC 0.35um SiGe. The key feature of this block is the maximum speed due to the rejection of feedbacks. A large range of output voltages and a low speed of their change allow the use of standard analog input modules for inputting phase detector signals to a computer for subsequent digital processing. The final accuracy of biological sensor signal phase detection is maintained at an acceptable level due to the introduction of additional elements in the basic circuit and the digital algorithms presented in the work. The shown variant of carrying out the correction has immunity to nonlinearities of the output characteristic of phase detection for large phase deviations of the signal of the biological sensor. The process technology used in the design is classified as economical, which makes it possible to potentially reduce the electrochemical impedance spectroscopy systems cost of production and introduction of a mass application.

In this article, we propose methods for designing fault-tolerant structures for Field Programmable Gate Arrays (FPGAs) by forming an internal structure of macro cells (LUTs), with the possibility of correcting single reversible faults in the circuit’s gates. To improve fault tolerance, the failure tolerance of a typical macro cell was assessed, the most vulnerable areas were identified and the most vulnerable parts of the macrocell were protected by means of triple modular redundancy methods. Depending on the expansion of the protected area, various versions of the built-in redundancy were obtained, and various options for minimizing the built-in redundancy were proposed. Experimental work was carried out to form fault-tolerant ISCAS'85 combinational circuit designs in the basis of fault-tolerant FPGAs.

Currently, issues of development of power efficient hardware blocks for digital signal processing (DSP) devices gain special importance. This is due to the rapid flourishing of wearable electronics, the Internet of things (IoT), network and telecommunication systems. The key component of many DSP devices is a finite impulse response (FIR) filter. It is not surprising that currently a large number of scientific papers are devoted to the development of power efficient FIR filters. The article proposes an original approach to the issue solution. As a methodological basis, modular arithmetic was chosen, already proven as an effective mathematical apparatus for the development of high-speed DSP devices. Another solution was the use of the FIR filter transposed form and methods for constructing the reduced blocks of the multiconstant multipliers. The experimental part demonstrated the efficiency of the block reduction methods of the multiconstant multiplication from the point of view of the filter power consumption. The article also made recommendations for the use of the proposed methods for specific implementations of the FIR filters.

The efficiency of algorithms of the adaptive temporal sampling (ATS) is defined by compressibility of an analog signal. For the purpose of prior assessment of compressibility of measuring signals the dependence of the current clock period of measurement in case of ATS from dynamic properties of a signal is considered. Depending on a priori known characteristics of dynamic properties of signals and the given error of approximation select a method of interpolation or extrapolation. In article the dependence of the current clock period of measurement on differential properties of a signal for an ideal algorithm of ATS of interpolation type is received. Restoration of a signal after ATS an interpolation polynomial of Lagrange n-oh of a level is supposed. The quality of approximation is set by criterion of uniform approximation. It is shown that the analysis of ideal ATS of interpolation type comes down to the analysis of the equivalent on value of a section of approximation of ideal ATS of extrapolation type.

The efficiency of algorithms of the adaptive temporal sampling (ATS) is defined by compression ratio of an analog signal. For the purpose of prior assessment of compressibility of measuring signals the dependence of the current clock period of measurement in case of ATS from dynamic properties of a signal is considered. Based on the dependence of the current clock period of measurement on dynamic properties of a signal received earlier, formulas for assessment of value of a clock period of measurement in case of interpolation are received by Lagrange's polynomial of a 0th level and a class of the signals restricted to the selected structural model. The functional dependence of the current clock period of measurement from structural properties of a signal, in case of Lagrange's polynomial of a 0th level, allows to determine the average duration of a clock period of measurement in case of ATS. Value of average duration of a clock period of measurement in case of ATS allows to estimate value of compression ratio a priori. As assessment of an error of approximation it is selected, often used in case of restoration of signals, criterion of uniform approximation.

Proposed technical solutions allow to set the amplitude of the clock signal individually for each functional unit.
