Salameh a.salameh@psau.edu.sa Kho Mei Ye meiye@um.edu.my <p>The Coarse-Grained Reconfigurable Array (CGRA) architecture for Efficient Processing-in-Memory (PIM) systems is presented in this article. PIM architectures that incorporate computational capabilities directly into memory present a promising solution to mitigate the memory wall issue. There are several difficulties in CGRA architecture optimization for PIM systems especially when it comes to striking a balance between area efficiency, power consumption and performance. The proposed framework tackles these problems by examining crucial design components like processing element (PE) architecture memory hierarchy integration and interconnect design. Using a design space exploration (DSE) methodology we assess various CGRA configurations to find the optimal trade-offs between computation throughput, power consumption and silicon area utilization. To assist in selecting effective architectures that meet different application workloads the framework combines performance analysis and advanced modeling techniques. Based on test results, the optimized CGRA architecture for PIM achieves significant improvements in processing performance (20 percent increase in throughput), area reduction and energy efficiency (up to 40 percent reduction in power consumption) when compared to conventional PIM designs. Our architecture is well-suited for data-intensive applications such as machine learning and graph analytics since these enhancements are achieved without compromising computational accuracy or scalability.</p> 2025-01-20T00:00:00+03:00 Copyright (c) 2024 https://vlsijournal.com/index.php/vlsi/article/view/149 Adaptive VLSI Design Using Dynamic Voltage and Frequency Scaling (DVFS) for Low-Latency IoT Communication Networks 2024-11-14T14:51:45+03:00 Anas A. Salameh a.salameh@psau.edu.sa Faizal Baharum baharumfaizal@gmail.com <p>The best and most compatible hardware solutions need to be developed to meet the growing demand for communication in Internet of Things (IoT) networks. This paper suggests using dynamic voltage and frequency scaling or DVFS for designing adaptive VLSI circuits for small IoT communication networks. DVFS is used to adjust the operating voltage and frequency of circuits and reduce power consumption when network traffic is light. It also maintains high-speed operation under heavy loads. By satisfying the requirements of the oscillating network the proposed VLSI design preserves low latency and high power efficiency. Simulations and prototype implementations show that in comparison to conventional VLSI designs the system features notable improvements in both communication speed and power consumption. These findings show that by strengthening power and traffic performance in IoT networks through the integration of VLSI circuits DVFS can be a good option for resource-constrained IoT devices and real-time applications.</p> 2025-01-20T00:00:00+03:00 Copyright (c) 2024 https://vlsijournal.com/index.php/vlsi/article/view/163 Design of a optimized CMOS Differential Amplifier using Craziness-based PSO 2025-01-29T10:29:23+03:00 Sandeep Kumar Dash sandeepfet@kiit.ac.in Bishnu Prasad De bishnu.defet@kiit.ac.in Bhargav Appasani bhargav.appasanifet@kiit.ac.in Nirmal Kumar Rout nkrout@kiit.ac.in Avireni Srinivasulu dean-ri@mbu.asia <p>Particle swarm optimization (PSO) is acomputational method used for solving different types of optimization problems. The social behaviors of fish schooling and flocks of birds mostly influence the PSO. PSO uses a collection of particles to explore the search space and locate the best possible solution.Each particle updates its position depending upon experience of itself or from neighboring particles, aiming to find the best solution in terms of the objective function being optimized.Crazinessbased Particle Swarm Optimization (CRPSO) is an advanced variation of the standard Particle Swarm Optimization (PSO) algorithm.CRPSO introduces a "craziness" factor to enhance the diversity of the swarm and prevent premature convergence to local optima.This paper deals with the design of a CMOS differential amplifier circuit with a current mirror load using CRPSO algorithm. The optimized sizes of the transistors are obtained using CRPSO to decrease the overall transistor area while meeting design limitations. The results achieved using the CRPSOare validated in the SPICE. The simulation result shows the superiority of CRPSO in the design of differential amplifier.</p> 2025-01-29T00:00:00+03:00 Copyright (c) 2025 https://vlsijournal.com/index.php/vlsi/article/view/152 Efficient Design of Up Sampler and Down Sampler using Single Electron Transistor-Metal Oxide Semiconductor Field Effect Transistor 2025-01-19T15:03:50+03:00 Shobhika Gopnarayan shobhna.g@myyahoo.com Shriram Markande sdmarkande@gmail.com <p>The increasing demand for high performance and low power, energy efficient electronics has led to significant advancements in nanoscale devices.

Padma pallavi.ch@svcolleges.edu.in R. Kiran Kumar pallavi.ch@svcolleges.edu.in T. Suguna pallavi.ch@svcolleges.edu.in C. Nalini pallavi.ch@svcolleges.edu.in <p>The main areas of research in VLSI system design include area, high speed, and power-efficient data route logic systems. The amount of time needed to send a carry through the adder limits the pace at which addition can occur in digital adders. One of the quickest adders, the Carry Select Adder (CSLA), is utilized by various data processing processors to carry out quick arithmetic operations. It is evident from the CSLA's structure that there is room to cut back on both the area and the delay. This work employs a straightforward and effective gate-level adjustment (in a regular structure) that significantly lowers the CSLA's area and delay. In light of this adjustment Square-Root Carry Select Adder (SQRT CSLA) designs with bit lengths of 8, 16, 32, and 64. When compared to the standard SQRT CSLA, the suggested design significantly reduces both area and latency. Xilinx ISE tool is used for Simulation and synthesis. The performance of the recommended designs in terms of delay is estimated in this study using the standard designs. The study of the findings indicates that the suggested CSLA structure outperforms the standard SQRT CSLA.</p> 2025-03-12T00:00:00+03:00 Copyright (c) 2025 Journal of VLSI Circuits and Systems https://vlsijournal.com/index.php/vlsi/article/view/180 Automated Compliance Systems in International Trade: The Role of AI and VLSI Systems in Streamlining Customs Procedures 2025-03-18T13:27:47+03:00 Marta Sarvas martasarvas@gmail.com Yuliya Bondarenko yulia.h.bondarenko@lpnu.ua Liliya Ukraynets liliya.ukrayinets@lnu.edu Pavlo Sorokovyi pavlo.m.sorokovyi@lpnu.ua Ivan Zhygalo ivan.i.zhyhalo@lpnu.ua <p>In an increasingly globalized economy, the efficiency of international trade is paramount, and customs procedures play a critical role in facilitating the smooth flow of goods across borders.

Latches serve as fundamental elements essential for the operation of sequential circuits in Internet of Things (IoT), Edge computing, and high-performance processors. The bulk of on-chip elements in a processor is often composed of sequential parts such as memory, registers, counters and flip-flops, wherein the foundational component is a data latch. This research paper puts forward two level sensitive latch energy- efficient designs using 6 transistors and 5 transistors respectively. The proposed designs are assessed under multiple supply voltages and temperatures. Additionally, corner analysis and Monte Carlo analysis are conducted on the proposed latch designs to validate their robustness and stability, ensuring their sustainability and ability to withstand high error rate at different operating conditions. The results confirm reduced energy consumption, delay and output noise with improved performance of the latches with an improvement of PDP by 10 folds and the delay is reduced by a factor of 10-2 with an area occupancy of 5.6024 µm2 and 4.7183 µm2 for the two proposed designs. Also, a 3-bit shift register is designed with the proposed design to demonstrate the successful application of these designs.</p> 2025-03-22T00:00:00+03:00 Copyright (c) 2025 Journal of VLSI Circuits and Systems
