Summary: This paper proposes a disturbance suppression zeroing neural network (DSZNN) for robust synchronization of chaotic and hyperchaotic systems, which is further validated on FPGA hardware. The DSZNN shows faster convergent speed and higher accuracy compared to SEZNN and CZNN. The superior performance of DSZNN is demonstrated through theoretical analysis, numerical simulations, and hardware validations.

Summary: Chaos has been widely used in secure communication, signal processing, and chaotic synchronization due to its sensitivity, ergodicity, boundedness, and unpredictability. However, existing one-dimensional chaotic maps have simple chaotic behaviors and discrete chaotic intervals, which affect practical applications. To address these issues, this paper proposes a one-dimensional chaotic model called the cosine-coupled chaotic model (CCCM) based on the absolute value function and the cosine function. Experimental results show that the new chaotic maps generated using the CCCM have wider chaotic intervals and more complex chaotic behaviors than the original maps and other advanced maps.

Summary: This article introduces a topology-aware matrix partitioning (TA-MP) method for accurate real-time simulation in high-frequency applications. The method uses an implicit numerical algorithm to ensure stability and employs iterative methods to solve implicit equations. By partitioning the PES matrix into blocks with topological meanings and constructing a constant iterative matrix using its constant diagonal blocks, the TA-MP method bypasses the limitations of using iterative methods in real-time simulations. The method eliminates the need to store inverse matrices and only requires matrix-vector multiplications, making it efficient on FPGA.

Summary: Time-sensitive networking (TSN) is a promising wired communication approach for industrial applications, but extending it to wireless networks requires solving synchronization and scheduling problems. While existing solutions meet the required synchronization accuracies, they rely on expensive hardware, prompting this article to propose a novel method using low-cost components for high-precision wireless synchronization with standard deviation of less than 500 ns.

Summary: This work proposes a method to generate 1-D pseudo-chaotic sequences based on the discrete Arnold's map defined over the integer ring Z(2)m. The period of the generated sequences is investigated using properties of the Fibonacci sequence over Z(2)m. The statistical properties of the PRNG are analyzed, and it is shown that the proposed PRNG has higher throughput and competitive hardware consumption compared to other architectures in the literature.

Summary: This paper presents a True Random Number Generator (TRNG) implemented using latched-XOR (LX) gates. The proposed TRNG improves the throughput of conventional TRNGs by combining latches metastability and ring oscillators jitter. Experimental results show that the generated bitstreams exhibit good randomness and the TRNG is robust to voltage and temperature variations. The FPGA implementation is compact and efficient, achieving high throughput.
