Simulate Rotor Hub Vortex Shedding In Helicopters


Although helicopter aerodynamics involves the same forces that arise in airplane aerodynamics, these forces occur differently due to fluid flow dynamics across the aircraft. Helicopters take advantage of the free stream flow along a rotor blade to produce lift and thrust. In rotating systems, the rotor hub clasps the blades and connects them to the main shaft of the system. The rotor in a h... » read more

Replicating da Vinci’s Aerial Vehicle Design


Unmanned aerial vehicles (UAVs), the prodigy of remotely piloted vehicles, largely used for military purposes, are slowly gaining momentum in our civil lives. Some of the applications of UAVs go beyond surveillance or photography: we already have drones that are employed by farmers to monitor crops and are used in the solar industry for thermographic studies. By 2026, UAVs for both consumer and... » read more

Internet Tech Trends For 2022


Every year at the start of the year, Benedict Evans produces a big presentation on trends in technology, internet, mobile, and so on. He used to live in the US and did this for Andreesen-Horowitz (a16z), but he has since returned to Britain (he's English) and I think has his own consulting company. This year's presentation is titled "Three Steps to the Future." The most exciting themes in t... » read more

Ensuring Functional Safety For Automotive AI Processors


Safety is critically important across the automotive, industrial, and aerospace and defense industries. For instance, Cadence's work with Hailo illustrates how advances in semiconductor technology and EDA deliver safe electronics without compromising low power and cost. Hailo's automotive webpage starts with the words "The pursuit for 'vision zero,'" reflecting that European road fatalitie... » read more

2022 Is the International Year of Glass


Happy New Year! It's 2022, and I like to ease into the year gently and see what this year is the "year of." The United Nations always selects a couple of areas, and there are events all over the world during the year. International Year of Glass First, it is the International Year of Glass, or IYoG2022. Our vision of a United Nations International Year of Glass (IYoG2022) is to cel... » read more

More Than Moore At iMAPS


San Diego recently hosted the 54th International Symposium on Microelectronics. That's a very generic title, so you should know that it is run by iMAPS, the International Microelectronics Assembly and Packaging Society. Generally, the conference is just known as iMAPS. One of the keynotes was given by Cadence's KT Moore (in person). His presentation was titled "More Moore or More than Moore: a... » read more

Ethernet Time-Sensitive Networking Adoption In The Automotive Industry


At a particular point in time, the automotive industry continued to add more and more sensors and electronic control units to vehicles. All these sensors and actuators used to connect through CAN and LIN buses. However, since the introduction of IVN (In-Vehicle Network), the industry has started replacing these buses with automotive Ethernet. According to NXP, “Ethernet enables broadband co... » read more

Implementing An AES Cipher On Application-Specific Processors


In the previous blog post, “Embedded Security Using Cryptography”, we looked at how cryptography can be used for securing assets in embedded systems and ensure confidentiality, integrity and authenticity, or in short “CIA”. In this blog, we will explore the Advanced Encryption Standard (AES) and how to implement an AES engine on Cadence Tensilica Xtensa application-specific processors. ... » read more

Embedded Security Using Cryptography


In the previous blog post, “Securing Offload Engines for a Robust Secure SoC System,” we briefly looked at some of the methods employed for achieving embedded security, i.e., cryptography, hardware partitioning and isolation, and hardware root of trust. In this blog, and subsequent blogs, we will explore more about each of these approaches in detail. Cryptography is not a new concept. It... » read more

Progress And Challenges On The CFD Vision 2030 Roadmap


After a long writing (and longer editing and approval seeking) process, the AIAA's CFD Vision 2030 Integration Committee has published its first update to the Vision's roadmap. This 71 page, thoroughly cited report assesses progress toward the Vision during 2020 and also provides a 5-year look-back. It covers the six domains along which the vision assesses progress in CFD: high performance comp... » read more
