Digital division is a pivotal operation in a number of domains, such as scientific computation, cryptography, digital signal processing, and machine learning, and has been broadly researched in the past decades. However, the increasing demand for efficient digital systems has emphasized the design of digital dividers with more stringent area and power costs without excessively compromising their performance. One option to achieve this is to implement Single Instruction Multiple Data (SIMD) dividers capable of exploiting the abundance of data-level parallelism, which is naturally present in common tasks such as stream processing, matrix normalization, and vector scaling. In this paper, we propose the designs of four configurable integer dividers capable of sustaining both Single Instruction Single Data (SISD) and SIMD computations, targeting different levels of performance and efficiency. Compared to one of the state-of-the-art integer dividers, our most efficient SIMD divider shows a 54% smaller area and 30% lower power consumption. Furthermore, we propose a novel technique which can reduce n-bit divisions to smaller (n−m)-bit ones, yielding a peek speedup of 15% when implemented in one of our proposed dividers.

During the last decade, many works have proven the important benefits of the analysis of different quantities under transient regimes for enhancing the diagnostic of the condition of electric motors. For instance, the analysis of starting currents and stray fluxes has proven to be very effective to avoid false indications obtained with classical tools, as well as to discriminate among different types of failures. The optimization of signal processing tools and image recognition algorithms that were too computationally expensive years ago has facilitated the proliferation of transient analysis techniques in the condition monitoring area. Moreover, the use of modern artificial intelligence (AI) methods has enabled to start implementing them in autonomous condition monitoring systems. Despite initially applied to induction motors and specific transient regimes and quantities, the use of these methodologies is being expanded to other machine typologies, other transients and even other quantities. This work compiles the recent advances in this area and proposes the extrapolation of startup transient analysis to other quantities such as vibrations. It is shown that the simultaneous analysis of different quantities under transient regimes enables to enhance the diagnostic and even to cover a wider range of faults.

Recurrent partial discharges (PD) in the insulation system of electrical machines result in accelerated insulation degeneration and a premature breakdown. Determining the repetitive PD inception voltage (RPDIV) of stators for automotive traction machines at the end of the production line following IEC/TS 61934 is mandatory to ensure a PD-free operation over the service life. The RPDIV depends on various influencing factors, which impedes the comparability of RPDIV results from different test systems. This paper introduces a PD detection platform to systematically investigate the RPDIV differences between two exemplary commercial PD testers. The proposed fusion between the PD signals received by a Horn antenna and a high-frequency current transformer is a suitable reference with a higher PD detection capability than the state-of-the-art systems. Three main influencing factors are identified to explain the RPDIV differences of up to 15 % between the commercial PD testers. The first one is the sensitivity of the antennas for PD detection, which is affected by the antenna design, the relative position to the stator, and the frequency band utilized in the signal processing. Second, differences in the rise time of the high-voltage surge pulses between 220 and 670 ns do not result in a consistent overall RPDIV trend. However, the RPDIV tends to increase with a longer rise time for some stators. Finally, measuring the test voltage directly at the stator terminals or estimating the actual voltage by correction factors is essential to avoid RPDIV differences caused by an inaccurate voltage measurement.

With the development of sonar technology, equipment for target detection and location based on underwater sound waves has experienced extensive applications. However, due to the limitations posed by the cost and operational cycle of underwater experiments, target and background simulators are necessary for the design, implementation, analysis, and performance testing of modern underwater guidance systems. In view of this, this study proposes a docking electrical-signal target background simulator, which can realistically simulate both the motion and spatial characteristics of underwater targets in real-time. Meanwhile, it can also simulate background noise and main background reverberation interference, which can effectively replace underwater tests. The proposed target background simulator uses a high-speed DSP(DigitalsignalProcessor)and a computer platform to realize real-time simulations of electrical signals received by array elements of an underwater guidance system in an actual underwater navigation state. In this study, both hardware composition and software design based on parallel processing are described in detail, and the generation principles of the target echo, background noise, and reverberation are discussed. The developed target background simulator is verified experimentally, and the results demonstrated strong real-time performance, expandable functions, and large dynamic range. Finally, the proposed design can be beneficial for the trial production of underwater guidance systems.

The growing demand for high-performance digital signal processing (DSP) systems necessitates the development of efficient digital filters with reduced power consumption, area, and computational complexity. The two important components of digital filters are multiplier and adder. This paper presents the design and implementation of digital filters utilizing a multiplexer-based truncated multiplier. The proposed approach focuses on optimizing multiplication operations, which are a critical component in digital filters, by minimizing the hardware resource usage while maintaining acceptable accuracy for DSP applications. The design methodology is detailed, including the architecture of the multiplier, integration into finite impulse response (FIR) filter, and the overall system workflow. Simulation and synthesis results obtained from Xilinx and Spartan-3E FPGA board demonstrate the performance of the proposed filter in terms of area, power, speed, and accuracy. Approximate Adders are used in place of adders in the digital filters. The findings indicate that the proposed design achieves significant improvements in efficiency compared to conventional filter implementations, making it a viable solution for resource-constrained applications in areas such as audio processing, communications, and embedded systems. © 2025 ieee.

Conventional steerable differential beamformers are usually only applicable to microphone arrays with regular planar geometries. Recent years have seen the interest in the design of steerable differential beamformers for microphone arrays with an arbitrary planar geometry. However, the existing steerable differential beamformers for arbitrary planar arrays need to repeatedly recalculate their beamformer weight vectors when the steering angle changes, which may affect their real-time implementation. In this paper, we propose a steerable differential polynomial (SDP) beamformer design approach based on the Farrow structures by using the Jacobi-Anger expansion and least-squares method. The SDP beamformers are applicable to arbitrary planar microphone arrays, and can realize continuous 360-degree mainlobe steering in real time without the need of updating beamformer weight vector, which is very useful for time-critical applications such as hearing assisting devices. Simulation results are also reported to demonstrate the effectiveness of the proposed SDP beamformers.

Recently, radar-based detection and tracking at millimeter-wave frequencies have become increasingly popular. However, the performance of the radar systems operating at millimeter-wave frequencies has been mainly limited to short ranges which makes them unsuitable for many practical applications. In this paper, long range detection and tracking for multiple targets at millimeter-wave frequencies is presented based on our custom-made Multiple Input Multiple Output (MIMO) radar system. The structure of the radar and the innovation in the digital signal processing unit will make it possible to perform detection and tracking for targets at far ranges. To the best of our knowledge, this is the first millimeter-wave system which is capable of detecting and tracking human at 600 m radial distance from the radar system. We present a complete statistical analysis of the combined land clutter and the noise of the system. This paves the way for the implementation of the Constant False Alarm Rate (CFAR) algorithm to detect the desired targets. Following the detection block the multi-target tracking is performed. The tracking unit is implemented based on the Kalman filtering and constant velocity motion model while the data association is based on the state-of-the-art Joint Probabilistic Data Association Filter (JPDAF). The algorithms have been implemented using the C programming language, and fully real-time processing has been achieved. The results presented in the paper are based on the experimental data gathered from realistic scenarios which demonstrate the capability of the radar system, which operates at 24 GHz, as well as the algorithms,

Fueled by advancements in intelligent transportation systems, the Internet of Vehicles (IoV) seeks to connect smart vehicles, road infrastructure, and users into a unified network, enhancing traffic efficiency and reducing accident risks. Centralized cloud data collection raises concerns about privacy and communication overhead. To address these, Distributed Edge Intelligence (DEI) reduces transmission costs and improves privacy by implementing machine learning at the network edge. In this context, Cooperative Adaptive Cruise Control (CACC) systems, combined with DEI in the IoV framework, enhance transportation system intelligence through real-time data processing and decentralized decision-making. This paper proposes a modeling and analysis method for CACC systems based on Petri nets. The datasets are automatically generated using tools developed by our team, and machine learning methods are utilized to perform risk prediction analysis on the CACC model. From the perspective of Petri nets synchronization, we propose risk mitigation strategies from a design standpoint. The research results show that the proposed method significantly reduces signal accumulation and enhances synchronization in CACC systems. This improvement provides new theoretical support and technical guidance for the design and implementation of CACC systems, ultimately enhancing their safety and reliability. © 2025 ieee.
