Zubko I. Improvement of models and method of increasing the efficiency of components of functionally-oriented special purpose systems

The work is devoted to the increase of speed and reliability of functionally-oriented computer systems of special purpose. The theme of the dissertation research, related to the improvement of methods and models for increasing the efficiency of components of functionally-oriented systems, is based on the integration of information converters to increase speed, reliability and energy efficiency in special purpose calculators. In carrying out research the following scientific and practical results were obtained. Improved model that converts binary code into unicarp Barker codes. The distinctive features of the model are expanded functionality in 2 times by integrating in it the functions of converting unipolar Barker codes into binary code, and when executed in a single crystal, reliability increases 103..104 times, as well as reliable functioning in the presence of noise barriers. Advanced model of special purpose calculator based on the piecewise linear approximation of control signals. A distinctive feature of the model is the increased speed by reducing the time of implementation of the control function by reducing the time of transient processes in 2·103 times The model of special purpose calculator on the basis of digital-analog transformations has got further development. A distinctive feature of the model is the expansion of functional capabilities by 3 times due to the piecewise linear approximation of special-purpose control signals, in addition, reliability increases in 103..104 times when executed in a single crystal. The method for improving the design of multi-component discrete devices has been further developed. The method is determined by a set of techniques in which the principles of conditional simulation are used, the properties of the theory of dimensions, conditional criteria, comparative analysis, and tools based on the visualization of dependencies between parameters. It includes: the creation of a generalized mathematical description, for linking the technical parameters, based on the characteristics of the subject of the study; visualization of dependencies of technical parameters in dimensionless coordinates on the basis of conditional criteria; analysis of visual data. A feature of the method is the identification of overloaded components, which provides increased reliability and longer operating time, preventing the possibility of failure of elements. Based on the synthesis, a physical experimental model for verifying the performance of the proposed transducer was constructed. Its feature is the established method of verifying performance, which, in line with traditional procedures, includes: developed algorithms for generation of input sequences using Arduino Uno and processing of input data by the hardware model in the FPGA module; procedure for outputting results to the monitor using microcomputer; comparison of the received two codes, as a result of the transformation of hardware and software simulation, comparison with the corresponding reference values in the event of their mismatch.
