Context. The article considers the problem of improving the eddy current device for metal identification on the basis of the correlation approach. This approach is convenient for the accumulation of a database of known leading materials, as well as for the comparison of the signal from an unknown metal object with the available standards in the database. The proposed approach allows to determine the type of metal from which the sample is made, without damaging its surface. Objective. The aim of the work is the identification of metals by type on the feedback signals from the eddy current converter, due to the identification of new informative features and the creation of a database of images of metals. Method. The paper presents the results of an experimental study of the proposed approach to increase the reliability of identification of metal objects that are detected using an eddy current device. These studies are conducted on the basis of a radio system that operates on the eddy current principle and has low-frequency magnetic loop antennas. The eddy current method allows the identification of metals by type remotely and without damaging their surface, in contrast to X-ray fluorescence, optical emission or chemical methods. A correlation approach for processing the response signal spectrum from a hidden metal object is proposed. The correlation approach allows to increase the reliability of the identification of metals by type when processing the signal in the spectral region based on the Fourier transform. Studies have been conducted on the example of metals that have similar spectral characteristics (silver, gold, lead). The updated approach allowed to increase the percentage difference between the information parameters of signals – responses from 1.87% to 5.02% for silver and gold, from 2.24% to 4.34% for silver and lead and from 0.36% to 0.7% for gold and lead. Results. The developed radio system is a laboratory model, which consists of an analog part and a digital one. The analog part is an antenna unit, a signal amplifier and a bandpass filter, a digital part – a microcontroller with an ADC for digitizing and transmitting data to a laptop, which software implements the proposed approaches to signal processing. The paper experimentally confirmed the possibility of using a radio engineering system to solve the problem of metal identification within a subset of nonmagnetic and magnetic materials. Conclusions. The development of modern eddy current devices is aimed at increasing the reliability of the identification the hidden metal objects, which is relevant in geophysical exploration, archeology, and law enforcement agencies in the search for hidden non-ferrous metals. The development and improvement of such systems includes both the development the hardware and the discovery new information parameters in the feedback signals from metals. One such direction may be the correlation approach to signal processing in the spectral region.

Context. Implementation of modular arithmetic operations of addition, subtraction and multiplication by a tabular method based on the use of the tabular multiplication code. The object of the study is the process of tabular implementation of basic arithmetic operations on the residues of numbers represented in the system of residual classes. Objective. The goal of the work is to develop methods for the tabular implementation of the arithmetic operations of multiplication, addition and subtraction of the residues of two numbers based on the use of the tabular multiplication code. Method. Tabular methods for implementing integer arithmetic modular operations of addition, subtraction and multiplication are proposed for consideration. In order to reduce the amount of equipment for a tabular operating unit of computer systems that implements modular operations of addition, subtraction and multiplication by reducing the coincidence circuits AND in the nodes of the tables for implementing arithmetic operations based on the code of table multiplication, two methods for performing arithmetic modular operations of addition and subtraction have been developed. These methods are based on the code of tabular multiplication, the use of which will reduce the amount of equipment of the tabular operating unit. Thus, despite the difference in the digital structure of the tables of modular operations of addition, subtraction and multiplication based on the use of the tabular multiplication code, two new tabular methods for implementing arithmetic modular operations of addition and subtraction have been created. Based on them, algorithms for tabular execution of modular arithmetic operations of addition and subtraction have been developed. Using these algorithms, it is possible to synthesize a structurally simple, highly reliable and fast table operating unit that operates in a system of residual classes, which is based on three separate permanent storage devices (read-only memory), each of which implements only one fourth of the corresponding complete table of values of the modular operation, what is earlier in the theory tabular arithmetic was supposed to be impossible. Results. The developed methods are justified theoretically and studied when performing arithmetic modular operations of addition, subtraction and multiplication using tabular procedures. Conclusions. The conducted examples of the implementation of integer arithmetic modular operations of addition and subtraction can be considered as presented experiments. The results obtained make it possible to recommend them for use in practice in the design of computer systems operating in a non-positional number system in residual classes. Prospects for further research may be to create a tabular method for implementing integer arithmetic modular division operations based on the use of the tabular multiplication code.
上下文。实现加法、减法和乘法的模块化算术运算,采用基于表格法的表格乘法代码。研究的对象是对残类系统中表示的数的残进行基本算术运算的表格实现过程。目标。工作的目标是开发基于使用表格乘法代码的两个数字的乘法,加法和减法的算术运算的表格实现方法。方法。提出了实现整数算术加法、减法和乘法的模运算的表格方法,以供考虑。为了减少计算机系统中实现加法、减法和乘法模块化运算的表格操作单元的设备数量,通过减少表节点中用于实现基于表乘法代码的算术运算的重合电路和,开发了两种执行加法和减法算术模块化运算的方法。这些方法都是基于表格乘法的代码,使用表格乘法可以减少表格操作单元的设备数量。因此,尽管基于表格乘法代码的加法、减法和乘法的模块化运算表的数字结构有所不同,但已经创建了两种新的表格方法来实现算术加法和减法的模块化运算。在此基础上,开发了模块化加法和减法运算的表格执行算法。利用这些算法,可以合成一个结构简单、高可靠和快速的表运算单元,该单元运行在剩余类系统中,该系统基于三个独立的永久存储设备(只读存储器),每个设备仅实现模块运算的相应完整表值的四分之一,这在早期的理论表格算法中是不可能的。结果。本文所提出的方法在用表格程序进行算术加法、减法和乘法的模运算时得到了理论证明和研究。结论。所进行的整数算术加法和减法模运算的实现实例可以看作是给出的实验。所得结果有可能推荐它们在残差类的非位置数系统的计算机系统设计中实际使用。进一步研究的前景可能是在使用表格乘法代码的基础上创建实现整数算术模除法的表格方法。

Context. The problem of synthesizing pulsed neural networks based on an evolutionary approach to the synthesis of artificial neural networks using a neuropathic mechanism for constructing diagnostic models with a high level of accuracy is considered. The object of research is the process of synthesis of pulsed neural networks using an evolutionary approach and a neuropathic mechanism. Objective of the work is to develop a method for synthesizing pulsed neural networks based on an evolutionary approach using a neuropathic mechanism to build diagnostic models with a high level of accuracy of work. Method. A method for synthesizing pulsed neural networks based on an evolutionary approach is proposed. At the beginning, a population of pulsed neural networks is generated, and a neuropathic mechanism is used for their encoding and further development, which consists in separate encoding of neurons with different activation functions that are determined beforehand. So each pattern with multiple entry points can define the relationship between a pair of points. In the future, this simplifies the evolutionary development of networks. To decipher a pulsed neural network from a pattern, the coordinates for a pair of neurons are passed to the network that creates the pattern. The network output determines the weight and delay of the connection between two neurons in a pulsed neural network. After that, you can evaluate each neuromodel after evolutionary changes and check the criteria for stopping synthesis. This method allows you to reduce the resource intensity during network synthesis by abstracting the evolutionary changes of the network pattern from itself. Results. The developed method is implemented and investigated on the example of the synthesis of a pulsed neural network for use as a model for technical diagnostics. Using the developed method to increase the accuracy of the neuromodel with a test sample by 20%, depending on the computing resources used. Conclusions. The conducted experiments confirmed the operability of the proposed mathematical software and allow us to recommend it for use in practice in the synthesis of pulsed neural networks as the basis of diagnostic models for further automation of tasks of diagnostics, forecasting, evaluation and pattern recognition using big data. Prospects for further research may lie in the use of a neuropathic mechanism for indirect encoding of pulsed neural networks, which will provide even more compact data storage and speed up the synthesis process.

Context. The behavior of the system is included in the basic concepts that characterize its functioning. In an event-driven system, behavior is modeled using a state machine. Known classifications of behavior take into account the genus and type of automaton. At the same time, in modern systems, control automata are integrated into hierarchies and have a number of new properties that are not reflected in their classifications. Objective. The purpose of the work is to systematize the forms of specifying the behavior of integrated systems and methods for changing the behavior in the process of their use. The novelty of the proposed classification lies in taking into account the behavior of new types of non-binary, semantic, controlled and changeable individual automata and the structures of these automata. Method. The essence of behavior is presented as the ambiguity of reactions to the input signals of the control automaton, which manifests itself in a certain pattern of changing its states and outputs. When classifying behaviors, the expediency of exploratory behavior is determined. Such ways of achieving the goal as adaptation, change or absorption of the environment, change in the goals of behavior are noted. According to the level of complexity of behavior, systems with predetermined, regulated, organizing, predictable and autonomous behavior are distinguished. Along with the automaton model of behavior, the importance of modeling behavior in the form of a combination of statements is noted. The importance of describing the possible and emergency behavior of the system is noted. A classification of the system’s behavior in terms of constancy and variability is proposed. The structure and principles of the implementation of changeable behavior within the framework of the processes of external control of the automaton and its selfgovernment are described. Based on the concept of arity of behavior, the functional and technological behavior of a finite automaton are singled out. As part of the classification of behavior by the level of formation, the switching, combinational and automatic behavior of states, as well as the behavior of the automaton in the contours of activity and the typical behavior of the automaton in the hierarchy, are described. Experiments. With the use of the proposed classification features, the behavior of control devices of monitoring systems for power transformer parameters, object temperature control and integrated hierarchical systems is analyzed. Results. The proposed classification describes the directions for specifying behavior in complex integrated systems according to 13 main and 84 detailing features, which facilitates the process of designing behavior and highlights new system capabilities. Conclusions. The actual problem of systematization of the behavior of control devices of systems has been solved.

上下文。系统的行为包含在表征其功能的基本概念中。在事件驱动的系统中,行为是使用状态机建模的。已知的行为分类考虑了自动机的属和类型。与此同时,在现代系统中,控制自动机被集成到层次结构中,并具有许多在其分类中没有反映出来的新属性。目标。这项工作的目的是将指定集成系统行为的形式和在使用过程中改变行为的方法系统化。该分类的新颖之处在于考虑了新型非二元、语义、受控和可变的个体自动机的行为以及这些自动机的结构。方法。行为的本质表现为控制自动机对输入信号的反应的模糊性,这种模糊性表现为改变控制自动机的状态和输出的某种模式。在对行为进行分类时,确定了探索性行为的权宜之计。实现目标的方式有适应、改变或吸收环境、改变行为目标等。根据行为的复杂程度,可以区分预定行为、调节行为、组织行为、可预测行为和自主行为。随着行为的自动机模型,以语句组合的形式对行为建模的重要性被注意到。指出了描述系统可能和紧急行为的重要性。提出了系统行为的恒常性和可变性分类方法。描述了在自动机及其自治的外部控制过程框架内实现可变行为的结构和原理。基于行为唯一性的概念,选取了有限自动机的功能行为和技术行为。作为形成层次行为分类的一部分,描述了状态的切换、组合和自动行为,以及自动机在活动轮廓中的行为和自动机在层次中的典型行为。实验。利用所提出的分类特征,分析了电力变压器参数监测系统、对象温度控制系统和综合分层系统的控制装置的行为。结果。该分类根据13个主要特征和84个详细特征描述了复杂集成系统中指定行为的方向,从而促进了设计行为的过程并突出了新的系统功能。结论。解决了系统控制装置行为系统化的实际问题。分类特征为使用标准解来描述系统的行为提供了指导,从而简化了过程并降低了设计其功能结构的复杂性。

Context. The problem of optimal control of the flow parameters of a transport system of a conveyor type in the presence of stepwise regulation of the speed of the conveyor section belt is considered. The object of the study is the analytical model of the transport conveyor, which was used as a foundation for the synthesis of optimal control algorithms for the flow parameters of the transport conveyor. The purpose of the work is to develop methods for designing systems for optimal control of the flow parameters of a transport conveyor, taking into account the transport delay with stepwise regulation of the flow parameters of the transport system. Method. An analytical model of the conveyor section has been developed, taking into account the stepwise regulation of the values of the flow parameters of the transport system. When building a model of a conveyor section to determine the dependencies between the flow parameters of the transport system, equations in partial derivatives are written. For the synthesis of algorithms for optimal control of the speed of the conveyor section belt, a control quality criterion is introduced. Using the Pontryagin maximum principle, the problem of optimal control of the flow parameters of the conveyor section is posed. For the transport system, the Hamilton function is written, which takes into account the criterion of control quality, imposed restrictions and differential relationships between the system parameters. A technique for synthesizing an algorithm for optimal control of the speed of a conveyor section belt is demonstrated. The conditions for switching the speed of the conveyor belt are determined. Results. The developed model of the conveyor section is used to synthesize an algorithm for optimal control of the flow parameters of the transport system with stepwise switching of belt speed modes.

Context. The pairwise comparison method is a component of several decision support methodologies such as the analytic hierarchy and network processes (AHP, ANP), PROMETHEE, TOPSIS and other. This method results in the weight vector of elements of decision-making model and is based on inversely symmetrical pairwise comparison matrices. The evaluation of the elements is carried out mainly by experts under conditions of uncertainty. Therefore, modifications of this method have been explored in recent years, which are based on fuzzy and interval pairwise comparison matrices (IPCMs). Objective. The purpose of the work is to develop a modified method for calculation of crisp weights based on consistent and inconsistent multiplicative IPCMs of elements of decision-making model. Method. The proposed modified method is based on consistent and inconsistent multiplicative IPCMs, fuzzy preference programming and results in more reliable weights for the elements of decision-making model in comparison with other known methods. The differences between the proposed method and the known ones are as follows: coefficients that characterize extended intervals for ratios of weights are introduced; membership functions of fuzzy preference relations are proposed, which depend on values of IPCM elements. The introduction of these coefficients and membership functions made it possible to prove the statement about the required coincidence of the calculated weights based on the “upper” and “lower” models. The introduced coefficients can be further used to find the most inconsistent IPCM elements. Results. Experiments were performed with several IPCMs of different consistency level. The weights on the basis of the considered consistent and weakly consistent IPCMs obtained using the proposed and other known methods have determined the same rankings of the compared objects. Therefore, the results using the proposed method on the basis of such IPCMs do not contradict the results obtained for these types of IPCMs using other known methods. Rankings by the proposed method based on the considered highly inconsistent IPCMs are much closer to rankings based on the corresponding initial undisturbed IPCMs in comparison with rankings obtained using the known FPP method. The most inconsistent elements in the considered IPCMs are found. Conclusions. The developed method has shown its efficiency, results in more reliable weights and can be used for a wide range of decision support problems, scenario analysis, priority calculation, resource allocation, evaluation of decision alternatives and criteria in various application areas.
上下文。两两比较法是层次分析法和网络分析法(AHP、ANP)、PROMETHEE、TOPSIS等多种决策支持方法的组成部分。该方法基于逆对称两两比较矩阵,得到决策模型各元素的权重向量。元素的评价主要由专家在不确定条件下进行。因此,近年来对该方法进行了改进,提出了基于模糊和区间两两比较矩阵(IPCMs)的改进方法。目标。本文的目的是基于决策模型要素的一致和不一致乘性ipcm,开发一种改进的脆度权重计算方法。方法。该方法基于一致性和非一致性乘性ipcm、模糊偏好规划,与其他已知方法相比,决策模型元素的权重更可靠。本文方法与已知方法的不同之处在于:引入了表征权重比的扩展区间的系数;提出了模糊偏好关系的隶属函数,该隶属函数依赖于IPCM元素的值。通过引入这些系数和隶属函数,可以证明基于“上”和“下”模型计算的权重需要符合的说法。引入的系数可以进一步用于寻找最不一致的IPCM元素。结果。用不同浓度的ipcm进行实验。使用所提出的方法和其他已知方法获得的考虑一致和弱一致的ipcm的基础上的权重确定了比较对象的相同排名。因此,使用基于此类ipcm的拟议方法的结果与使用其他已知方法对这些类型的ipcm获得的结果并不矛盾。与使用已知FPP方法获得的排名相比,基于考虑的高度不一致ipcm的所提出方法的排名更接近基于相应的初始未扰动ipcm的排名。在考虑的ipcm中发现了最不一致的元素。结论。所开发的方法已显示出其效率,结果更可靠的权重,可用于各种应用领域的决策支持问题,场景分析,优先级计算,资源分配,决策方案和标准的评估。

The developed method of increasing the accuracy of MEMC navigation data processing of an inertial navigation system of an unmanned aerial vehicle based on an advanced Madgwik filter shows an advantage over known methods in the absence of corrective signals from the global satellite navigation system for accuracy and speed of navigation data processing.

Context. The problem of localization of the effect of errors in data transmission channels when using compression and noiseimmune coding methods in the conditions of compliance with the speed of data delivery in infocommunication systems of the aerosegment. The object of the study is coding methods for increasing the reliability of video information resources in infocommunication networks using airmobile platforms. Objective. The goal of the work is to methodology development of increasing the reliability of video information in the infocommunication networks of the aerosegment. Method. The use of noise-immune coding methods to ensure the required level of reliability of video information transmitted in infocommunication systems of the aerosegment has a number of significant disadvantages: it leads to a significant increase in the bit volume of compactly presented video data; the time delay for the delivery of video information is growing, which is critical in the conditions of using airmobile platforms. An increase in time delays in the process of delivering video information leads to the fact that the video information will not be transmitted in full and, as a consequence, in the conditions of aeromonitoring, to the loss of data reliability; time for processing video data increases. The advantage of using compression coding technologies to solve the problem of increasing the reliability of video information transmitted in infocommunication systems of the aerosegment is to reduce the bit volume of the video information resource. However, the existing video processing technologies are based on the use of statistical coding methods and the identification of a series of identical sequences of repeating elements. But the use of such technologies does not provide the required level of error localization. Restructuring method was developed based on identifying patterns in the internal binary structure of message elements by a quantitative attribute. The sign of the number of series of units in the binary structure of message elements is used as a tool for restructuring. Distinctive features of the method are that the restructuring of the information space is carried out without loss of integrity on the basis of structural features by the number of binary series. Results. The analysis of existing directions for solving the problem of increasing the level of reliability of video information transmitted in the infocommunication systems of the aerosegment was carried out. A method of internal data restructuring has been developed, which allows obtaining the following results: conditions are provided for additional reduction of structural redundancy of code representation of information due to significant reduction of information space capacity as a result of using internal data restructuring on the basis of the number of series of units; conditions are created for localization of errors in the process of reconstruction of video information resources; c
上下文。在符合航段信息通信系统数据传输速度的条件下,采用压缩和抗噪声编码方法对数据传输信道中误差影响的定位问题。本文的研究对象是基于空中移动平台的信息通信网络中提高视频信息资源可靠性的编码方法。目标。这项工作的目标是提高航空段信息通信网络中视频信息的可靠性的方法学发展。方法。使用抗噪声编码方法来确保航空段信息通信系统中传输的视频信息所需的可靠性水平有许多明显的缺点:它导致紧凑呈现的视频数据的比特量显着增加;视频信息传输的时间延迟越来越大,这在使用空中移动平台的条件下是至关重要的。视频信息传输过程中的时间延迟增加,导致视频信息传输不完整,在航空监控条件下,数据可靠性降低;处理视频数据的时间增加了。采用压缩编码技术来解决航段信息通信系统中提高视频信息传输可靠性的问题,其优点是减少了视频信息资源的比特量。然而,现有的视频处理技术是基于使用统计编码方法和识别一系列相同的重复元素序列。但是,使用这些技术并不能提供所需的错误定位水平。提出了一种基于定量属性识别消息元素内部二元结构模式的重构方法。在消息元素的二进制结构中,序列单元的数量符号被用作重组的工具。该方法的显著特点是在结构特征的基础上,通过二元序列的个数对信息空间进行重构而不损失完整性。结果。分析了提高航段信息通信系统中视频信息传输可靠性问题的现有解决方向。已经开发了一种内部数据重组方法,该方法允许获得以下结果:由于使用基于单元系列数量的内部数据重组导致信息空间容量显著减少,因此为进一步减少信息代码表示的结构冗余提供了条件;为视频信息资源重建过程中的错误定位创造了条件;创建条件是为了减少数据处理的时间,因为所开发的数据重构方法不需要对消息元素进行转换。结论。有必要在模式识别的方向上改进现有的压缩编码技术,考虑到这将允许定位通信信道中产生的错误的破坏性影响。

It is caused by that such systems became popular and cheap vehicle platforms for highperformance calculations. In addition, practice pulls out problems complete decision of which in most cases possibly only due to application of high-performance calculations. Consequently, a theme of constructing of the cluster multiprocessor systems for today is actual, interesting and is on the stage of the active development. At the same time, the new high-quality stage of development of the multiprocessor cluster systems lies in area of the use of new modern network technologies. Presently the problem of choice and analysis of network technologies for the module multiprocessor cluster systems did not get due development, as well as problem of reorganization of structure ofnetwork interfaceby aggregating of channels of network interface. Objective. An aim is in-process put improvement of structure and increase of the productivity of the multiprocessor computer system by the multidimensional aggregating of channels of network interface, adapted to the decision of tasks of the investigated class. Method. The task of increase of efficiency of the module multiprocessor computer system is decided due to multidimensional aggregating of channels of network interface. Offered approach allowed not only to promote efficiency of parallelization but also substantially to decrease time of calculations. Such results succeeded to be attained due to diminishing to time of border exchange of data between the calculable knots of the cluster system. Results. A feature offered approach is that he allowed to realize a direct exchange data between main memory of knots of the multiprocessor system, that promotes the fast-acting of calculations and provides high-speed access to memory of her slave -nodes. Thus during an exchange by data between the knots of the system the system CPU gets unloaded and loading of channel which passes between the knots of the computer system goes down, that assists diminishing of time of border exchange of data between the calculable knots of the system. Conclusions. The results of the conducted experiments showed that the worked out multiprocessor system was used for creation of new technological processes. So, she is used in a fluidizer intensification of the сфероидизируещего annealing of long-length steelwork. Directly the technological process of heat treatment of metal acquires such advantages, as a high yield, substantial mionectic energy consumption and allows to carry out control of technological parameters in the modes of unisothermal treatment of metal.

At the same time, the new high-quality stage of development of the multiprocessor cluster systems lies in area of the use of new modern network technologies. Presently the problem of choice and analysis of network technologies for the module multiprocessor cluster systems did not get due development, as well as problem of reorganization of structure ofnetwork interfaceby aggregating of channels of network interface. \u0000Objective. An aim is in-process put improvement of structure and increase of the productivity of the multiprocessor computer system by the multidimensional aggregating of channels of network interface, adapted to the decision of tasks of the investigated class. \u0000Method. The task of increase of efficiency of the module multiprocessor computer system is decided due to multidimensional aggregating of channels of network interface. Offered approach allowed not only to promote efficiency of parallelization but also substantially to decrease time of calculations. Such results succeeded to be attained due to diminishing to time of border exchange of data between the calculable knots of the cluster system. \u0000Results. A feature offered approach is that he allowed to realize a direct exchange data between main memory of knots of the multiprocessor system, that promotes the fast-acting of calculations and provides high-speed access to memory of her slave -nodes. Thus during an exchange by data between the knots of the system the system CPU gets unloaded and loading of channel which passes between the knots of the computer system goes down, that assists diminishing of time of border exchange of data between the calculable knots of the system. \u0000Conclusions. The results of the conducted experiments showed that the worked out multiprocessor system was used for creation of new technological processes. So, she is used in a fluidizer intensification of the сфероидизируещего annealing of long-length steelwork. Directly the technological process of heat treatment of metal acquires such advantages, as a high yield, substantial mionectic energy consumption and allows to carry out control of technological parameters in the modes of unisothermal treatment of metal.","PeriodicalId":43783,"journal":{"name":"Radio Electronics Computer Science Control","volume":"56 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84551380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Context. The problem of formalizing the description of a microprogram finite state machine based on the principle of operational transformation of state codes with the help of a modified transition table is considered. The object of research was a model of a microprogram finite state machine with datapath of transitions. Objective. The goal of the work is development and research of a method for formally specifying a microprogram finite state machine with datapath of transitions in the form of a modified table of transitions containing sufficient information for synthesizing the logic circuit of the finite state machine in the basis of programmable logic devices. Method. A new way of representing the formal solution of the problem of algebraic synthesis of a microprogram finite state machine with datapath of transitions in the form of an operational table of transitions is proposed. This table is a modification of the direct structural table traditionally used in the synthesis of microprogram finite state machines. The use of the previously known representation of the formal solution of the problem of algebraic synthesis in the form of a system of isomorphisms of automaton algebras is too formalized and makes it difficult to synthesize the logical circuit of the finite state machine due to the separate description of the transition and output functions. It is shown that the structure of a microprogram finite state machine with datapath of transitions requires information about the set of interpretations of state codes and the transition operations used to be entered into the traditional table of transitions. It is noted that the proposed operational table of transitions contains sufficient information for the synthesis of the logical circuit of the finite state machine. An example of constructing an operational table of transitions for a finite state machine given by a graph-scheme of the implemented control algorithm is shown. The example demonstrates various ways to interpret state codes. The procedure for synthesizing the circuit for generating codes of transition operations and the circuit for generating microoperations according to the operational table of transitions is proposed. Results. An example of the implementation of the main stages of the synthesis of a finite state machine with datapath of transitions according to the operational table of transitions is considered. Examples of synthesized finite state machine models in the VHDL language are given, which take into account the peculiarities of the representation of finite state machine models in Xilinx Vivado CAD. The results of the synthesis of the finite state machine according to VHDL models in FPGA basis are shown. Conclusions. The experiments carried out confirmed the sufficiency of the operational table of transitions for describing a microprogram finite state machine with operational transformation of state codes for the purpose of further synthesizing its logic circuit.

上下文。基于状态码的操作变换原理,利用改进的转换表,研究了微程序有限状态机的形式化描述问题。研究的对象是具有数据转换路径的微程序有限状态机模型。目标。本工作的目标是开发和研究一种正式指定微程序有限状态机的方法,该方法以转换数据路径的修改转换表的形式包含足够的信息,以便在可编程逻辑器件的基础上综合有限状态机的逻辑电路。方法。提出了一种用转换运算表形式表示具有转换数据路径的微程序有限状态机代数综合问题的形式化解的新方法。这个表是对传统上用于微程序有限状态机综合的直接结构表的改进。用自动机代数同构系统的形式来表示代数综合问题的形式解过于形式化,并且由于转换函数和输出函数的单独描述而使有限状态机的逻辑电路难以综合。研究表明,具有转换数据路径的微程序有限状态机的结构需要关于状态码的解释集和用于输入传统转换表的转换操作的信息。文中指出,所提出的转换运算表包含了有限状态机逻辑电路综合的足够信息。给出了用所实现的控制算法的图格式给出的有限状态机转换操作表的构造实例。该示例演示了解释州代码的各种方法。提出了根据转换操作表合成转换操作代码生成电路和微操作生成电路的程序。结果。考虑了一个基于转换操作表的有限状态机数据路径综合的主要阶段的实现实例。考虑到Xilinx Vivado CAD中有限状态机模型表示的特殊性,给出了用VHDL语言构建有限状态机模型的实例。给出了基于FPGA的VHDL模型综合有限状态机的结果。结论。实验证实了转换运算表描述微程序有限状态机状态码运算变换的充分性,从而进一步综合其逻辑电路。进一步研究的前景是利用所提出的转换运算表开发各种方法来综合和优化具有状态码运算转换的微程序有限状态机。
