Performance Boost In Powerful Real-Time Cortex-R Processor Using Data Prefetch Control
By Arm - 10 Apr, 2024 - Comments: 0

High-performance processors employ hardware data prefetching to reduce the negative performance impact of large main memory latencies. An effective prefetching mechanism can improve cache hit rate significantly. Data prefetching boosts the execution performance by fetching data before it is needed. While prefetching improves performance substantially on many programs, it can significantly red... » read more

Hybrid Methodology To Extract Kinetic And Magnetic Inductances For Superconductor Technologies
By Siemens EDA - 10 Apr, 2024 - Comments: 0

Integrated circuits (ICs) using superconductors have emerged as the technology of choice for artificial intelligence (AI), data centers, and cloud computing. However, innovative technology requires equally innovative physical verification solutions to ensure that these superconductor ICs deliver the performance and reliability they promise. We introduce an innovative hybrid methodology to extra... » read more

Low-Power Relaxation Oscillator With Temperature-Compensated Thyristor Decision Elements
By Fraunhofer IIS/EAS - 10 Apr, 2024 - Comments: 0

This paper presents a low-power 140 kHz relaxation oscillator (ROSC) for low-frequency clock generators and timers. In voltage-mode ROSCs, unavoidable shunt current consumption results from voltage slewing at the integration capacitor. The proposed circuit employs CMOS thyristor-based decision elements which effectively reduce shunt currents by exploiting internal positive feedback. A complemen... » read more

PCI Express Test Overview
By Keysight - 10 Apr, 2024 - Comments: 0

PCl Express, short for Peripheral Component Interconnect Express, is a high-performance and high-bandwidth serial communication interconnect standard. First proposed by Intel and further developed by the Peripheral Component Interconnect Special Interest Group (PCI-SIG) in replacement of bus-based communication architecture, such as PCI, PCI Extended (PCI-X), and Accelerated Graphics Port (AGP)... » read more

Quantum Well Design Basics
By Cadence - 10 Apr, 2024 - Comments: 0

Key Takeaways The choice of materials for the quantum well and barrier layers is paramount. Materials must have compatible lattice structures to minimize defects, with common combinations including GaAs/AlGaAs, InGaAs/InP, and GaN/AlGaN. The width of the quantum well significantly influences the energy levels and density of states, where narrower wells result in greater separation betwe... » read more

Amplify Simulation Via Effective Data And Process Management
By Ansys - 10 Apr, 2024 - Comments: 0

Over the past 50 years, engineering simulation has proven its value by reducing development time and costs, as well as dramatically improving product performance. By subjecting their designs to real-world physical forces in a risk-free virtual environment, product development teams can identify issues and address them at an early stage, thus minimizing expensive rework, prototyping, and physica... » read more

Research Bits: April 8
By Jesse Allen - 08 Apr, 2024 - Comments: 0

Annealing processor Researchers from the Tokyo University of Science designed a scalable, fully-coupled annealing processor with 4096 spins on a single board with 36 CMOS chips, with parallelized capabilities for accelerated solving of combinatorial optimization problems. "We want to achieve advanced information processing directly at the edge, rather than in the cloud, or performing prepro... » read more

Stretchy, sensitive circuits Researchers from Stanford University developed skin-like, stretchable integrated circuits capable of driving a micro-LED screen with a refresh rate of 60 Hz and detecting a braille array that is more sensitive than human fingertips. The stretchable transistors are made from semiconducting carbon nanotubes sandwiched between soft elastic electronic materials. The... » read more

The Challenges Of Working With Photonics
By Karen Heyman - 01 Apr, 2024 - Comments: 0

Experts at the Table: Semiconductor Engineering sat down to talk about where photonics is most useful — and most vulnerable — with James Pond, fellow at Ansys; Gilles Lamant, distinguished engineer at Cadence; and Mitch Heins, business development manager for photonic solutions at Synopsys. What follows are excerpts of that conversation. To view part one of this discussion, click here. ... » read more

Research Bits: March 26
By Jesse Allen - 26 Mar, 2024 - Comments: 0

Skyrmion switches Researchers from the Agency for Science, Technology and Research (A*STAR) and National University of Singapore harnessed skyrmions to build a switch that has the potential to process data faster while using significantly less energy. Skyrmions are magnetic whirls that form in very thin metal layers and can be efficiently moved between magnetic regions. Using a magnetic tun... » read more
