Abstract:
The concept presented in this paper fits into the current trend of highly secured hardware authentication designs utilizing Physically Unclonable Functions (PUFs) or Physical Obfuscated Keys (POKs). We propose an idea that the PUF cryptographic keys can be derived from a chaotic circuit. We point out that the chaos theory should be explored for the sake of PUFs as a natural mechanism of amplifying random process variations of digital circuits. We prove the idea based on a novel design of a chaotic circuit, which utilizes time in a feedback loop as an analog continuous variable in a purely digital system. Our design is small and simple, and therefore feasible to implement in inexpensive reprogrammable devices (not equipped with digital clock manager, programmable delay line, phase locked loop, RAM/ROM memory, etc.). Preliminary tests proved that the chaotic circuit PUFs work in both advanced Field-Programmable Gate Arrays (FPGAs) as well as simple Complex Programmable Logic Devices (CPLDs). We showed that different PUF challenges (slightly different implementations based on variations in elements placement and/or routing) have provided significantly different keys generated within one CPLD/FPGA device. On the other hand, the same PUF challenges used in a different CPLD/FPGA instance (programmed with precisely the same bit-stream resulting in exactly the same placement and routing) have enhanced differences between devices resulting in different cryptographic keys.

Abstract:
The Programmable Array Logic (PAL)-based logic block is the core of the great majority of Complex Programmable Logic Devices (CPLDs). The purpose of this paper is to compare two models of decomposition dedicated to PAL-based devices. Non-standard usage of decomposition, which leads to the reduction of used PAL-based logic blocks in a programmable structure, is the aim of the presented methods. Each decomposition step is optimized for implementation in a PAL-based structure that is characterized by a PAL-based logic block. The essence of decomposition models is oriented towards minimizing the number of PAL-based logic blocks used and adjusting the designed circuit to fit the structures of PAL-based blocks best. In the experimental section, a comparison of two decomposition models with the classical implementation approach is presented. Results of the experiments prove that the proposed methods lead to a significant reduction of chip area in relation to the classical approach, especially if CPLD structures consist of PAL-based blocks containing a relatively small number of product terms.

Abstract:
The paper focuses on the methodology of designing a cyber physical systems (CPS) physical layer using programmable devices. The CPS physical layer can be implemented in programmable devices, which leads to a reduction in their costs and increases their versatility. One of the groups of programmable devices are complex programmable logic devices (CPLDs), which are great for energy-saving, low-cost implementations but requiring flexibility. It becomes necessary to develop mathematical CPS design methods focused on CPLD. This paper presents an original technology mapping method for digital circuits in programmable array logic (PAL)-based CPLDs. The idea is associated with the process of multilevel optimization of circuits dedicated to minimization of the area of a final solution. In the technology mapping process, the method of a multioutput function was used in the graph of outputs form. This method is well known from previous papers and proposes optimization of a basic form of the graph of outputs to enable better use of the resources of a programmable structure. The possibilities for the graph of outputs were expanded in the form of sequential circuits. This work presents a new form of a graph that describes the process of mapping and is known as the graph of excitations and outputs. This graph enables effective technology mapping of sequential circuits. The paper presents a series of experiments that prove the efficiency of the proposed methods for technology mapping. Experiments were conducted for various sizes of PAL-based logic blocks and commercially available CPLDs. The presented results indicate the possibility of more effective implementation of the CPS physical layer.

Abstract:
In this paper the fitting problem for a new Application Specific State Machine Device, CY7C361, from Cypress Semiconductor is formulated and the solution is proposed. This fitting problem consists of mapping a netlist obtained from high-level synthesis into the chip’s physical resources. In general, a mapping (fitting) problem can be formulated as one of the labeled graph isomorphism between the netlist graph and the subgraph of the resources graph. However, the specific architecture-related constraints of the CY7C361 device cause the fitting problem to be generalized as a graph isomorphism problem with some additional mapping constraints and node multiplication (placing some nodes of the netlist graph in more than one node of the physical graph). Such formulation is quite general for a class of Complex Programmable Logic Device (CPLD) fitting problems, and has not been found in the literature. We implemented an exact, constraint-based, tree searching algorithm with several kinds of backtracking.

Abstract:
In this paper, the authors present the noise suppression performance using a decoupling capacitor which is embedded in an LTCC substrate. To embed high value capacitors (>20nF), a high K (over 500) material which can be co-fired with low K LTCC was developed successfully. Thin high K sheets under 10μm were co-laminated between low K sheets, which form the power and ground planes. Due to the short distance from the IC power pin to the decoupling capacitor, the ESL (Equivalent Series Inductance) is much lower than with surface mounted type capacitors, and so, SSN (Simultaneous Switching Noise) can be reduced significantly. To verify the noise suppression performance, we designed and fabricated a digital module using 100MHz CPLD (Complex Programmable Logic Device) on top of the LTCC substrate in which a 25nF decoupling capacitor was embedded. By measurement, we can see that SSN of CPLD on LTCC was reduced by 80% compared with designs that use surface mounted type 100nF capacitors. This embedded decoupling capacitor in LTCC (LEDC) can be useful for digital SiP (System In Package) to enhance noise performance and to reduce its footprint.

Abstract:
<span>In the developed system ARM9 is a master and Two ARM7s are slaves. The peripherals are being controlled by two ARM7 boards. The Peripherals are connected to the ARM7 through Complex Programmable Logic Device (CPLD). The CPLD is in turn connected to the ARM7 using Serial Peripheral Interface (SPI). The ARM7 boards collect the information from the peripherals and send it to the ARM9 board. The communication between ARM7 and ARM9 is via UART (Universal Asynchronous Receiver Transmitter) over CAN (Controller Area Network). The ARM9 board has got the software intelligence. The ARM9 behaves as a master and two ARM7 boards behave as slaves. Being master ARM9 passes tokens to ARM7 which in turn returns (Acknowledges) the token. The ARM9 is further connected to Proxy via Ethernet. The proxy is further connected to the service platform (server) via Ethernet. So subsequently any decisions at any stage can be changed at server level. Further these commands can be passed on to ARM9 which in turn controls the peripherals through ARM7. (a) The system which we have developed consists of ARM9 as a master, Two ARM7 as Slaves. The communication between ARM9-ARM7 is via UART over a CAN, <br /> (b) Each ARM7 further communicates serially (RS232) with the two 8051 Microcontroller nodes, (c)Thus a networked Embedded System is developed wherein the serial data is brought over Ethernet. The ARM7 board, which is directly linked with the peripherals, can be modified of its functionality as and when required. The functionality of ARM7 can be modified by upgrading its firmware. To upgrade the firmware same communication link has been used. ARM7 receives the new firmware via same ARM9-ARM7 communication link. The Flash Write operation is performed using the source code to write the new firmware. Bootloader application for the ARM7 has been developed. The signature has been incorporated to assure authenticity of the new Firmware. Intel Hex File Format is used to parse the hex file.</span>

Abstract:
Programmable logic designs are presented that achieve exact integration of leaky integrate-and-fire soma and dynamical synapse neuronal models and incorporate spike-time dependent plasticity and axonal delays. Highly accurate numerical performance has been achieved by modifying simpler forward-Euler-based circuitry requiring minimal circuit allocation, which, as we show, behaves equivalently to exact integration. These designs have been implemented and simulated at the behavioral and physical device levels, demonstrating close agreement with both numerical and analytical results. By exploiting finely grained parallelism and single clock cycle numerical iteration, these designs achieve simulation speeds at least five orders of magnitude faster than the nervous system, termed here hyper-real-time operation, when deployed on commercially available field-programmable gate array (FPGA) devices. Taken together, our designs form a programmable logic construction kit of commonly used neuronal model elements that supports the building of large and complex architectures of spiking neuron networks for real-time neuromorphic implementation, neurophysiological interfacing, or efficient parameter space investigations.

Abstract:
Field Programmable Gate Array (FPGA) is a general purpose programmable logic device that can be configured by a customer after manufacturing to perform from a simple logic gate operations to complex systems on chip or even artificial intelligence systems. Scientific publications related to FPGA started in 1992 and, up to now, we found more than 70,000 documents in the two leading scientific databases (Scopus and Clarivative Web of Science). These publications show the vast range of applications based on FPGAs, from the new mechanism that enables the magnetic suspension system for the kilogram redefinition, to the Mars rovers’ navigation systems. This paper reviews the top FPGAs’ applications by a scientometric analysis in ScientoPy, covering publications related to FPGAs from 1992 to 2018. Here we found the top 150 applications that we divided into the following categories: digital control, communication interfaces, networking, computer security, cryptography techniques, machine learning, digital signal processing, image and video processing, big data, computer algorithms and other applications. Also, we present an evolution and trend analysis of the related applications.

However, with the advancement of chip technology and the continuous upgrading of information technology, the functions that FPGAs need to perform are more and more complicated. How to efficiently perform layout design and make full use of chip resources has become an important technology to be solved and optimized in FPGA design. The FPGA itself is not limited to a specific function. It contains internal functions such as memory, protocol module, clock module, high-speed interface module and digital signal processing. It can be programmed through logic modules such as programmable logic unit modules and interconnects. Blank FPGA devices are designed to be high performance system applications with complex functions. The layout and routing technology based on cluster logic unit blocks can combine the above resources to give full play to its performance advantages, and its importance is self-evident. Based on the traditional FPGA implementation, this paper analyzes several advantages based on cluster logic block layout and routing technology, and generalizes the design method and flow based on cluster logic block layout and routing technology.

Abstract:
This paper analyzes the design automation of embedded Systolic Array Processors (SAPs), into large scale Field Programmable Gate Array (FPGA) devices. SAPs are hardware implementations of a class of iterative, high-level language algorithms, for applications where the high-speed of processing has the principal meaning of a design. Embedding SAPs onto FPGAs is a complex process. The optimization phase in this process reduces the SAP significantly, thus less FPGA area is occupied by the embedded design, without any loss in the final performance. The present paper examines the effect of Projection Vectors (PVs) and Task Scheduling Vectors (TSVs) on the optimization process. Two optimization approaches are examined, namely technology mapping using FlowMap and Flowpack algorithms and optimization via logic synthesis using Xilinx Synthesis Tool. The multiplication of matrices, with entries being up to 32-bit integer vectors, has been taken as a sample space for the experiments conducted. The results, confirm that the selection of PV and TSV greatly affects the number of input/output signal connections of the FPGA, while the selection of an optimization approach affects the final number of logic resources occupied on the targeted device.

This paper introduces the hardware and programming involved in collecting the image of the digital code wheel by microprocessor STM32 directly driving camera chip OV7670 and the transmission of collected image. This design simplifies the hardware structure to the greatest extent and minimizes cost. Our design has three advantages. Fist, direct driving saves the intermediary register chip, simplifies the circuit and also reduces the amount of elements used. Second, by using the CMOS digital image sensor with windowing function—OV7670 to capture the image of code wheel we simplify the hardware structure and reduces the cost because of the D/A conversion circuit and complex programmable logic device contained in OV7670. Third, we successively solve the problem of the small capacity (20k) of STM32F103C8T6 chip’s SRAM by cutting out 24080 images from 640480. So time spent on data transmission and processing can be shortened.

Abstract:
The experience of the Joint Forces operation (Anti-terrorist operation in Donetsk and Luhansk oblasts) shows that the current order of management of military radio communication systems does not always meet the modern requirements for them. The classic centralized approach to the management of channel and network resources of military radio systems does not quite meet modern requirements, so the authors of this article proposed to take mobile self-organizing networks as a basic principle of construction. The authors propose a comprehensive method of managing the parameters of military radio networks in conditions of uncertainty of the electronic environment, the essence of which is to ensure the maintenance of the specified values of the performance of military radio communication systems at the appropriate level. The article is based on the control principle, which is described in the reference network model of open systems interaction, but with some additions and changes. This approach generally allows for end-to-end management of channel and network resources of military radio systems in a complex electronic environment. In the article, the device of fuzzy logic, the theory of electronic suppression, neural networks, the theory of noise protection, the theory of antennas, noise-resistant coding are used. The proposed complex methodology should be used in the development of software for modules (units) for the assessment of advanced radio communications, based on open architecture interfaces version SCA 2.2, which will: use effective signal-code structures to ensure noise immunity of channels; to ensure efficient use of the radio frequency resource of programmable radio communication means; increase the speed of evaluation of communication channels; reduce the use of computing resources of radio communications with programmable architecture.

Abstract:
The Boolean satisfiability (SAT) problem is the key problem in computer theory and application. A novel algorithm is introduced to implement a SLS hardware solver called probSAT+. The algorithm has no complex heuristic, and it only depends on the concepts of preprocessing technology, probability distribution and centralized search. Through constraining the initial assignments of the variables, the number of flipped variables was reduced while the solver finding a solution. Moreover, the algorithm no longer adopts some non-continuous if-then-else decisions, but depends on a single continuous function f(x,v). The flipping probability is not obtained by complex calculations, instead being selected by looking up tables, which effectively improves the performance of the solver. As far as we know, the probability distribution selection strategy descripted by hardware description language is firstly adopted by hardware SAT solver, which can be easily transplanted to any programmable logic device. The experimental results show that the probSAT+ solver is generally lower than the advanced software solver in the number of flips (up to 9.8 × 10 6 ), and the speedup is approximately 2.6 times with single thread, which shows that the probSAT+ has better results with fewer variables flipping times when a solution can be found. In addition, the success ratio of the solver in finding a solution of the problem in a suitable time is 100%.

Abstract:
Functional electrical stimulation (FES) device has been widely used by spinal cord injury (SCI) patients in their rehab exercises to restore motor function to their paralysed muscles. The major challenge of muscle contraction induced by FES is early muscle fatigue due to the open-loop stimulation strategy. To reduce the early muscle fatigue phenomenon, a closed-loop FES system is proposed to track the angle of the limb’s movement and provide an accurate amount of charge according to the desired reference angle. Among the existing feedback controllers, fuzzy logic controller (FLC) has been found to exhibit good control performance in handling complex non-linear systems without developing any complex mathematical model. Recently, there has been considerable interest in the implementation of FLC in hardware embedded systems. Therefore, in this paper, a digital fuzzy feedback controller (FFC) embedded in a field-programmable gate array (FPGA) board was proposed. The digital FFC mainly consists of an analog-to-digital converter (ADC) Data Acquisition and FLC sub-modules. The FFC was designed to monitor and control the progress of knee extension movement by regulating the stimulus pulse width duration to meet the target angle. The knee is expected to extend to a maximum reference angle setting (70°, 40° or 30°) from its normal position of 0° once the stimulus charge is applied to the muscle by the FES device. Initially, the FLC was modelled using MATLAB Simulink. Then, the FLC was hardcoded into digital logic using hardware description language (HDL) Verilog codes. Thereafter, the performance of the digital FLC was tested with a knee extension model using the HDL co-simulation technique in MATLAB Simulink. Finally, for real-time verification, the designed digital FFC was downloaded to the Intel FPGA (DE2-115) board. The digital FFC utilized only 4% of the total FPGA (Cyclone IV E) logic elements (LEs) and required 238 µs to regulate stimulus pulse width data, including 3 µs for the FLC computation. The high processing speed of the digital FFC enables the stimulus pulse width duration to be updated every stimulation cycle. Furthermore, the implemented digital FFC has demonstrated good control performance in accurately controlling the stimulus pulse width duration to reach the desired reference angle with very small overshoot (1.4°) and steady-state error (0.4°). These promising results are very useful for a real-world closed-loop FES application.

Abstract:
The paper aims at describing a model-based approach to design automation logics for fault location and supply restoration in medium voltage distribution networks. The application of automation functions along medium voltage feeders and, in particular, the installation of protection devices in secondary substations mandates the design and the implementation of complex logics to coordinate the operations of this hardware in case of fault occurrences. This synchronization is realized with the exchange of IEC 61850 GOOSE messages, but the correct usage of this information must be implemented in each protection device through dedicated logics, which are not in the common out-of-the-box system configurations. To support the introduction and the design of these logics, an automata-based approach has been proposed and successfully demonstrated in a real environment in the European research project IDE4L. This formal methodology has been introduced to simplify the design phase and to standardize the logics implemented in the protection prototypes realized in the project. The same models have also been used in the implementation phase with a semi-automatic code generation procedure, considering as a target system the software programmable logic controllers (soft-PLCs), available on the protection devices. Based on the test results and the short time to set up the test bench, this approach proved to be a reliable and effective way to implement complex medium voltage (MV) automation logics such those needed in modern smart grids.

Abstract:
The purpose of these studies is to develop an effective structure and internal functional blocks of a digital computing device – an adder, that performs addition and subtraction operations on floating- point numbers presented in IEEE Std 754TM-2008 format. To improve the characteristics of the adder, the circuit uses conveying, that is, division into levels, each of which performs a specific action on numbers. This allows you to perform addition / subtraction operations on several numbers at the same time, which increas- es the performance of calculations, and also makes the adder suitable for use in modern synchronous cir- cuits. Each block of the conveyor structure of the adder on FPGA is synthesized as a separate project of a digital functional unit, and thus, the overall task is divided into separate subtasks, which facilitates experi- mental testing and phased debugging of the entire device. Experimental studies were performed using EDA Quartus II. The developed circuit was modeled on FPGAs of the Stratix III and Cyclone III family. An ana- logue of the developed circuit was a functionally similar device from Altera. A comparative analysis is made and reasoned conclusions are drawn that the performance improvement is achieved due to the conveyor structure of the adder. Implementation of arithmetic over the floating-point numbers on programmable logic integrated cir- cuits, in particular on FPGA, has such advantages as flexibility of use and low production costs, and also provides the opportunity to solve problems for which there are no ready-made solutions in the form of stand- ard devices presented on the market. The developed adder has a wide scope, since most modern computing devices need to process floating-point numbers. The proposed conveyor model of the adder is quite simple to implement on the FPGA and can be an alternative to using built-in multipliers and processor cores in cases where the complex functionality of these devices is redundant for a specific task.

Abstract:
The topical issues of development of automated control systems of gas control stations (GCS) and ways of reliable and economical functioning of the gas supply system in modern conditions have been considered in the article. The implementation of European innovative technologies, which are associated with using the modern equipment, telemetry tools to transmit the equipment operation parameters to the dispatcher control panel are the one of the ways to increase the safety and efficiency of GCS performance. The characteristic of the modern complex of telemetry, the raising of efficiency, reliability and safe operation of the gas supply systems due to the possibility of monitoring, technological control and management from the central dispatcher control room are given. The complex of telemetry helps to prevent emergency situations at facilities and to ensure control over unauthorized entry into the GCS premises by unauthorized persons. The article discusses the use of the automated system of operative-dispatching management (ASODM). It is a multi-level automated system that ensures the reliable functioning of the gas supply system at all levels of the hierarchy. It has been shown that the result of the creation of the ASODM are equipping of the control object with microprocessor control and management devices, the integration of various automation tools into a single information management system. It has been proven that the development of ASODM of GCS on the basis of local control and management modules using traditional approaches to creation of automation systems and using the cellular telephone communication as data transmission channels based on GSM-technologies are most rational. The digital control device, which is made on the technological platform of the programmable logic integrated circuit (PLIC), is the main element of the local control and management module. Digital control device (PLIC controller) is a relatively inexpensive and reliable equipment in an automated local GCS control system. The method of data transmission via GSM / GPRS wireless communication channel is considered. The use of GSM-modems and GPRS technology allows to remove restrictions on the distance of data transmission, as well as allows to fully automate the process of transmission and processing of information. The use of GSM / GPRS-technologies in the vehicles of the emergency dispatch service is also shown. The dispatcher can fully monitor the movement of the car with registration on the map of the city where the car is located.
