  An Overview on VLSI based Hardware Security in IoT Node

  By Kazi Kutubuddin Sayyad Liyakat, Heena Shaikh, Dr. Kosgiker G M

  Abstract: In the coming era, security will not be a feature we add to an IoT device; it will be a property inherent to its transistor-level design. By encoding security into the VLSI architecture, we move away from the fragile "software-only" paradigm and toward a future where the identity of the device is as immutable as the laws of physics. The rapid proliferation of Internet of Things (IoT) devices has transformed …

  64 Bit ALU DESIGN USING VEDIC MATHEMATHICS

  By Sirigineedi Mounisha, Uppalapati Joshna Venkata Srujana, Vemula Rajesh, Velugubanti Lakshman, Yepuganti Manikanta, I.Rama Satya.Nageswara Rao, Saran Kumar

  Abstract: High-speed arithmetic operations are crucial for better performance in contemporary digital systems. Particularly for high bit-width operations, conventional arithmetic logic units (ALUs) frequently experience increased latency and complexity. This work presents the design and implementation of a 64-bit Arithmetic Logic Unit (ALU) using notions from Vedic mathematics. The suggested design makes use of a Kogge-Stone Adder for effective addition and the Urdhva Tiryagbhyam sutra for quick multiplication. Among other mathematical …

  Spintronic Logic Circuits for Ultrafast Processing

  By Vaibhav Godase, Shilpa Shinde

  Abstract: Spintronic logic has emerged as one of the most promising post-CMOS paradigms capable of addressing the speed, density, and energy challenges of deeply scaled silicon technologies. By relying on the intrinsic properties of electron spin and magnetization dynamics, spintronic devices—particularly Magnetic Tunnel Junctions (MTJs), Spin-Transfer Torque (STT), and Spin–Orbit Torque (SOT) structures—enable ultrafast, non-volatile data processing with significantly reduced energy consumption. Despite remarkable device-level advancements, circuit- level realization of high-speed, …
