What’s In A Name(space)? Optimizing SSD Controller Performance And Verification


Solid state drives (SSDs) have come to the forefront as a promising solution for today and tomorrow’s immense data transfer and storage demands. And SSDs themselves are constantly evolving with upgrades of their critical components to provide higher access speeds. One such component for the NVMe specification is created by the division of non-volatile memory (NVM) into what are commonly known... » read more

Meeting 112 SerDes Based System Design Challenges


The need for higher bandwidth networking equipment as well as connectivity in the cloud and hyperscale data centers is driving the switch technology transition from 25Tb/s (terabytes) to 51Tb/s and soon to 100Tb/s. The industry has chosen Ethernet to drive the switch market, using 112G SerDes or PHY technology today and 224G SerDes in the future. This article describes how designers can overcom... » read more

Open RAN Phase 2


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

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


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

Building High Voltage Automotive Battery Management Systems


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


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

How To Create A Physics-Based Laser Compact Model For A Photonic Process Design Kit (PDK)


This paper discusses the importance of accurate laser compact models in photonic process design kits, describes different laser models available in Ansys Lumerical INTERCONNECT, and explains optimal steps to create a laser compact model that includes temperature and noise effects.

A Holistic Approach To Energy-Efficient System-On-Chip (SoC) Design


It takes a great deal of energy to power the modern world, and demand grows every day. This is especially true for electronics, where ever increasing automation and more intelligent devices incessantly demand more power. Many applications that use chips face a variety of pressures for reduced power consumption and better energy efficiency. In response, the semiconductor and electronic design au... » read more

Research Bits: May 9


Optical oscilloscope Researchers from the University of Central Florida developed an optical oscilloscope to measure the electric field of light. The high speed at which light oscillates has made reading its electric field challenging, with current instruments able to resolve an average signal associated with a pulse of light rather than individual peaks and valleys within the pulse. “... » read more
