PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids

The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

Hard matrix multiplier blocks in field-programmable gate arrays

Rapidly changing algorithms and network architectures in the field of machine learning make Field Programmable Gate Array (FPGA) based designs an attractive solution for accelerating neural networks. However, the generic building blocks available in current FPGAs limit the acceleration that can be achieved. This technology, developed by researchers...

CSALT: Context switch aware large translation look-aside buffer (TLB)

BackgroundContext Switch Aware Large TLB (CSALT) addresses the problem of increased TLB miss rates and their adverse impact on data caches. The invention proposes to partition the on-chip caches to house translation entries (TLB entries/page table entries) alongside data. The partitioning is achieved by means of a low overhead cache partitioning algorithm...

Very large DRAM-based TLB

Background Cloud services use virtualization platforms to provide their services. These platforms use hypervisors to enable easier scalability of applications and higher system utilization by abstracting the underlying host resources. Unfortunately, these systems have an increased level of memory virtualization pressure, as hypervisors and guests keep...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers

Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

All-Fiber Multicore Fiber Laser Devices

Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
