This brief presents a 2-lane discrete multitone (DMT) wireline receiver (RX) with a far-end crosstalk (FEXT) cancellation and its implementation on the ZCU111 RFSoC evaluation board for real-time functional verification. The RX datapath is implemented with the 64-parallel 128-tap multi-path delay-feedback (MDF) fast Fourier transform (FFT) to optimize resources and throughput. The multiple-input, multiple-output (MIMO) frequency-domain equalizer (FDE) compensates both channel insertion loss (IL) and FEXT based on coefficients computed from an on-chip pilot-assist channel estimation (CHEST). The platform includes a programmable logic (PL) for a DMT digital signal processor (DSP) running at 32 MHz, 2.048 GS/s data converters, and intersymbol interference (ISI)/FEXT board. This system enables the reflection of a realistic hardware impairment and real-time transceiver (TRX) operation with a quick bit error rate (BER) test. The measurement demonstrates that the MIMO DMT significantly improves a BER from 1.0E-2 to 5.8E-7 when the FEXT is canceled for a channel exhibiting 15 dB of IL and 10 dB of IL-to-crosstalk ratio (ICR) at Nyquist frequency.

Automatic cache partitioning method for high-level synthesis

MICROPROCESSORS AND MICROSYSTEMS 2019年 67卷 71-81页

Existing algorithms can be automatically translated from software to hardware using High-Level Synthesis (HLS), allowing for quick prototyping or deployment of embedded designs. High-level software is written with a single main memory in mind, whereas hardware designs can take advantage of many parallel memories. The translation and optimization of memory usage, and the generation of resulting architectures, is important for high-performance designs. Tools provide optimizations on memory structures targeting data reuse and partitioning, but generally these are applied separately for a given object in memory. Memory access that cannot be effectively optimized is serialized to the memory, hindering any further parallelization of the surrounding generated hardware. In this work, we present an automated optimization method for creating custom cache memory architectures for HLS generated designs. Our optimization uses runtime profiling data, and is performed at a localized scope. This method combines data reuse savings and memory partitioning to further increase the potential parallelism and alleviate the serialized memory access, increasing performance. Comparisons are made against architectures without this optimization, and against other HLS caching approaches. Results are presented showing this method requires 72% of the number of execution cycles compared to a single-cache design, and 31% compared to designs with no caches. (C) 2019 Elsevier B.V.

This work deals with the development of an open-loop wind turbine emulator to verify the system operation with respect to the wind profile. The emulator consists essentially of a 300 W DC motor powered by DC/DC buck converter which controlled through field-programmable gate array (FPGA) and pulse-width modulation strategy. The motor rotational speed allows to imitate proportionally different wind velocity. A hardware test bench based on the fast prototyping method using MATLAB/Xilinx System Generation (XSG) environment and FPGA board of wind turbine simulator is built to validate the simulation results. Simulation and experimental results confirm the efficiency of the implemented method to make the proposed emulator able to react as a real wind in laboratory.

The trend toward further integration of automotive electronic control units functionality into domain control units as well as the rise of computing-intensive driver assistance systems has led to a demand for high-performance automotive computation platforms. These platforms have to fulfill stringent safety requirements. One promising approach is the use of performance computation units in combination with safety controllers in a single control unit. Such systems require adequate communication links between the computation units. While Ethernet is widely used, a high-speed serial link communication protocol supported by an Infineon AURIX safety controller appears to be a promising alternative. In this paper, a high-speed serial link IP core is presented, which enables this type of high-speed serial link communication interface for field-programmable gate array-based computing units. In our test setup, the IP core was implemented in a high-performance Xilinx Zynq UltraScale+, which communicated with an Infineon AURIX via high-speed serial link and Ethernet. The first bandwidth measurements demonstrated that high-speed serial link is an interesting candidate for inter-chip communication, resulting in bandwidths reaching up to 127 Mbit/s using stream transmissions.

The reversible computation is an emerging research field, which is used in different applications such as optical computing, digital signal processing, nanotechnologies, bio-information and in low-power computation. In present days, these applications require security algorithm to keep the information securely. The power and area analysis are one of the major challenges to mathematically secure cryptography protocols. Moreover, hackers can take confidential data while it passes through the transmission line. To overcome this problem, Reversible logic cryptography design (RLCD) architecture is introduced in this paper. With the help of RLCD, the encryption and decryption architecture is designed. Linear feedback shift register (LFSR) is required to produce a key which is given to the encryption and decryption block. The application specified integrated chip (ASIC) and field-programmable gate array (FPGA) performances are evaluated for both existing and proposed method. More than 7% of the ASIC performances improved in RLCD-LFSR method compared to the conventional methods. (C) 2019 Elsevier B.V. All rights reserved.

Pseudo-Sensorless High-Performance Bilateral Teleoperation by Sliding-Mode Control and FPGA

引用

IEEE-ASME TRANSACTIONS ON MECHATRONICS 2014年第1期19卷 384-393页

作者： Hace, Ales Franc, Marko Univ Maribor Inst Robot SLO-2000 Maribor Slovenia Isomat Doo Mezica 2392 Slovenia

This paper proposes a pseudo-sensorless implementation of scaled bilateral teleoperation. It is based on Hall effect sensors that are built within the motor housing. The proposed implementation requires no external sensor that can deteriorate system dynamics and performance. The integrated sensors have been used both for position measurement and external force estimation that are necessary in high-performance bilateral teleoperation. Nevertheless, system perturbation dynamics may always appear in a practical mechatronic system. Therefore, the chattering-free sliding-mode control algorithm is applied that ensures robustness toward the disturbances, and yet is easy to implement. The data acquisition algorithms as well as the control algorithm are implemented by field-programmable gate array (FPGA) in order to provide high control rate that can further increase robustness required for haptic fidelity of the system for scaled teleoperation. The applied algorithms along with the FGPA implementation were validated by the 2-DoF experimental system. It has been shown that the proposed pseudo-sensorless implementation by FPGA provides high bilateral teleoperation performance.

Software-defined radio (SDR) research deals with a mixture of hardware and software technologies, where RF operating parameters and components are to be set or altered by modifiable software or firmware. This paper describes the coarse-grained reconfigurable array (CGRA) implementations of SDR architecture. This architecture is an extension of traditional SDR in complex adaptation strategies, such as highly reliable communications and efficient utilization of the resources and spectrum upgrade, through its internal states (performance) and hardware architecture. The proposed CGRA-based SDR implementation is based on dynamic partial reconfiguration methodology, which has the capability of reusing the same hardware module to handle different algorithms. This CGRA-based SDR provides greater flexibility and adds new abilities without additional cost. Initially, the SDR system was simulated in the Agilent SystemVue environment to analyze the error boundaries of the proposed SDR architecture. Then the SDR system was coded in the Verilog hardware description language and implemented on top of CGRAs such as the MOLEN, MORPHOSYS, and ADRES reconfigurable system-on-chip (SoC) architectures. These SoC architectures were installed within the Xilinx Virtex 5 field-programmable gate array to analyze the performance of SDR architectures in terms of area utilization, operational speed, power optimization, reconfiguration time, coprocessor execution time, preemption support, and relocation support of the system. The performance analysis indicates that the ADRES SoC architecture is suitable for dynamic partial reconfiguration and the MOLEN SoC architecture is more suitable for power, area, and speed requirements and low circuit complexity compared to other architectures.

Stability-guaranteed predictive sliding surface control of silicon carbide dual-output nine-switch inverter

In this study, a finite control set model predictive control strategy is proposed for a nine-switch converter system. The predictive control routine with discrete-solution space in energy transformation applications is widely used and offers a satisfactory closed-loop operation. However, the stability analysis of the predictive control method is a challenging task, and the practical stability approaches are applied to examine the closed-loop stability characteristics. Designing the guaranteed-stability predictive control is not an easy task since even the norm choice of the objective function may result in closed-loop instability. Regarding closed-loop stability, stability-guaranteed predictive sliding surface control approach is introduced in this study. The multi-objective cost function is reformulated in the proposed method as a sliding surface function usually used in sliding mode control methods. Thus, the best-suited control input that meets the sliding mode control stability criterion is picked. The proposed reformulation process enables the sliding surface function as an objective function, and the sliding surface function is gauged for each legitimate switching combination. The proposed control method is experimentally verified by using a 3.2 kW silicon carbide nine-switch inverter prototype. The experimental results prove that the proposed method guarantees closed-loop stability, and dual-AC load control is achieved.

Design of a Multiple Pseudorandom Number Generator Combined Chaotic System With RNS and Its Application to Secure Image Processing

引用

IEEE ACCESS 2024年 12卷 155246-155258页

作者： Liu, Chien-Chun Chen, Chih-Chiang Yan, Jun-Juh Liao, Teh-Lu Natl Cheng Kung Univ Dept Engn Sci Tainan 70101 Taiwan Air Force Inst Technol Dept Aircraft Engn Kaohsiung 82063 Taiwan Natl Cheng Kung Univ Dept Syst & Naval Mechatron Engn Tainan 70101 Taiwan Natl Chin Yi Univ Technol Dept Elect Engn Taichung 41107 Taiwan

This paper presents a novel approach to designing a multiple pseudorandom number generator (MPNG) through the integration of several key techniques. Specifically, the method leverages the chaotic dynamics of the 2D Tinkerbell system, a residue number system (RNS), and XOR operations to generate multiple sets of pseudorandom number sequences. The MPNG offers several advantages, including a simple design and low hardware resource requirements. Implemented using a field-programmable gate array (FPGA), it applies each chaotic system state to produce three sets of random number sequences, achieving a generation rate three times higher. The generated sequences are rigorously evaluated using the NIST SP800-22 and Diehard test suites, along with Shannon entropy and histogram analyses, all of which confirm their randomness. The results pass all NIST SP800-22 and Diehard test items, demonstrating the properties of random numbers. Additionally, this paper proposes a synchronization controller to achieve state synchronization between the master system and the slave system, enabling symmetric encryption and decryption applications for secure image processing.
