Open RAN Phase 2
By Paul McLellan - 12 May, 2022 - Comments: 0

I first wrote about Open RAN in my post Fourth 4G Network Goes Live in Japan. Open RAN is a program driven by a group of European operators to build specifications for common architecture instead of getting "locked into" the closed architectures sold by the big base-station vendors such as Nokia, Samsung, and Ericsson. It is analogous to what servers went through over the last few decades, m... » read more

FICS Research Institute: Detailed Assessment of the PQC Candidates To Power Side Channel Attacks
By Technical Paper Link - 11 May, 2022 - Comments: 0

New research paper by a team of researchers from FICS Research Institute titled "PQC-SEP: Power Side-Channel Evaluation Platform for Post-Quantum Cryptography Algorithms." Abstract "Research in post-quantum cryptography (PQC) aims to develop cryptographic algorithms that can withstand classical and quantum attacks. The recent advance in the PQC field has gradually switched from the theory t... » read more

Software-Defined Cars
By Ann Mutschler - 11 May, 2022 - Comments: 0

Automotive architectures are becoming increasingly software-driven, a shift that simplifies upgrades and makes it easier to add new features into vehicles. All of this is enabled by the increasing digitalization of automotive functions and features, shifting from mechanical to electrical design, and increasingly from analog to digital data. That enables OEMs to add or up-sell features years ... » read more

NVMe-oF: Simple, Invisible Fabric For Distributed Storage Networks

In today’s fast paced world, we need seamless access to huge chunks of data and new-world technologies, such as artificial intelligence (AI), machine learning (ML), cloud computing, and real-time data analytics. AI researchers are deriving applications such as cyber security analysis and intelligent virtual assistants (IVA) where the computer needs to process an intense amount of data. Theref... » read more

Every Walk’s A Hit: Making Page Walks Single-Access Cache Hits
By Arm - 11 May, 2022 - Comments: 0

As memory capacity has outstripped TLB coverage, large data applications suffer from frequent page table walks. We investigate two complementary techniques for addressing this cost: reducing the number of accesses required and reducing the latency of each access. The first approach is accomplished by opportunistically "flattening" the page table: merging two levels of traditional 4 KB p... » read more

Blog Review: May 11
By Jesse Allen - 11 May, 2022 - Comments: 0

Ansys' Vidyu Challa checks out how to identify the most important battery metrics for a particular application and trade these off against others with a focus on the important considerations when selecting the right battery for a consumer application, such as rechargeability, energy density, power density, shelf life, safety, form factor, cost, and flexibility. Cadence's Shyam Sharma points ... » read more

Building High Voltage Automotive Battery Management Systems
By Infineon - 11 May, 2022 - Comments: 0

To ensure safety, performance and accuracy over the full system lifetime, it is essential to choose the right BMS components. This can also maximize the range and lifetime obtainable from the Li-ion battery, which is a vital differentiator for carmakers. The paper gives a general introduction to Li-ion batteries and BMS, before presenting Infineon’s products and system approach towards offer... » read more

State-Space Model Of An Electro-Mechanical-Acoustic Contactless Energy Transfer System Based On Multiphysics Networks
By Fraunhofer IIS/EAS - 11 May, 2022 - Comments: 0

Contactless energy transfer systems are mainly divided into acoustic, inductive, capacitive and optical, in which main applications are related to biomedical, wireless chargers and sensors in metal enclosures. When solids are used as transfer media, ultrasound transducers based on piezoelectricity can be used for through-wall power transfer, which can be named as electro-mechanical-acoustic con... » read more

Compound Semiconductor Innovation Advances EVs And Other Green Technologies
By Rupa Velidandla - 11 May, 2022 - Comments: 0

As the world works to reduce greenhouse gas emissions, global adoption of electric vehicles (EVs) is driving an increased demand for high-power, energy-efficient compound semiconductors, such as silicon carbide (SiC)-based components, throughout the entire EV assembly process. Renewable energy technology is now at the forefront of climate-forward research, with accelerating EV sales playing�... » read more
