Design and Optimization of Coarse-Grained Reconfigurable Array (CGRA) Architecture for Efficient Processing-in-Memory (PIM) Systems

2024-11-14T14:18:16+03:00

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.

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.

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.

Design of a 64-bit SQRT-CSLA with Reduced Area and High-Speed Applications in Low Power VLSI Circuits

2025-02-28T10:59:33+03:00

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.

As per the escalating demand for portable and battery-powered electronic devices, the requirement of energy-efficient, high-speed devices with minimal area has become increasingly imperative in this era of sustainable electronics and green computing. 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.
