Collaborative virtual reality environments for the home office

Collaborative VR visualization of a multi-generational community center. Credit: HLRS/Fabian Dembski Simulations using supercomputers or construction data from CAD systems are normally visualized and analyzed in a Cave 3-D facility. In an era of “social distancing” resulting from the coronavirus pandemic, however, this is not always possible. To address this problem, visualization experts from six universities in Baden-Württemberg, including members of the Visualization Department of the High-Performance Computing Center Stuttgart (HLRS), working together in a project titled “Virtual Collaboration Laboratories…

Set-Top Boxes Evolve from Media-Consumption Device to Smart-Home Hub

Change is overtaking the set-top box. Don’t worry: It still merits its place next to our television sets. But a confluence of three powerful forces bears down on the familiar little box, transmuting it into something new and remarkable in both function and architecture. The locus of this transformation is the SoC at the box’s heart, where the forces demand machine-learning acceleration at an unprecedented price/performance point. Three Forces in Play What are the three forces pushing the set-top box…

Using OpenAMP to Address Mixed Safety-Critical Systems

Multi-processor systems-on-chip (MPSoCs) are increasingly becoming the hardware offering of choice among embedded-systems designers. Driving this trend are market demands for increased performance and capacity, lower power consumption, and lower bill-of-materials (BOM) costs. The consolidated hardware and subsystems increase the complexity of the associated embedded software, including the ability to address subsystem hardware isolation features like safety zones that make multicore enablement and use even more challenging. Emerging from these technological advances is the concept of mixed safety-critical systems. A…

German firm creates bionic birds

Credit: Festo Some might say it’s for the birds. But the latest creation from German robotics company Festo promises not only literal flights of fancy, but quite promising real-world applications down the road as well. The company unveiled a video of a stunningly lifelike fleet of robo-birds that glide through the air with guidance from an ultra-sideband radio system. Festo has been an innovator of miniaturized robotic devices for years. They have manufactured robotic seagulls, jellyfish, butterflies and kangaroos. Their…

Intel i740: Big Investments, Major Embarrassments

>> Electronic Design Resources.. >> Library: Article Series.. .. >> Series: The Graphics Chip Chronicles.. .. .. >> Introduction to this Series.. .. .. Intel has tried several times to get into the stand-alone graphics chip market. Its first attempt in 1982 came with the cross licensing of the NEC 7220, which became the Intel 82720. In 1983, Intel rolled out the iSBX 275 Multibus-based add-in graphics board (AIB) with the chip. Its second attempt was in 1988 when it…

11 Myths of Signal Integrity in High-Density Backplanes

As a signal travels across a network, it focuses only on what it sees in its path. And increases in data rates over the past few decades have made this path a bit more clouded. System infrastructure needs to accommodate such increases through better bandwidth management, better system interoperability, and higher data throughput. This is no short order. Many of these challenges are being handled in the backplane, which manages much of the interconnect between various circuit boards or cards…

Oz tech titans to build world’s tallest ‘hybrid timber’ tower in Sydney

The Atlassian building is designed by New York architects SHoP and Australian firm BVN Global software giant Atlassian will build the world’s tallest “hybrid timber” building for its new headquarters in Sydney, the company said Thursday. The 40-storey structure, coming in at 180 metres (590 ft), will be constructed with timber mass—layers of softwoods pressed together—and will feature a glass and steel facade, topped by outdoor gardens. The Atlassian building, designed by New York architects SHoP and Australian firm BVN,…

Capturing moving subjects in still-life quality

Credit: Ecole Polytechnique Federale de Lausanne Researchers at EPFL’s Advanced Quantum Architecture Laboratory and the Wision Laboratory at the University of Wisconsin-Madison have developed a technique for building crystal-clear images of moving subjects. The team will present its paper at the prestigious SIGGRAPH 2020 conference in August. In 2019, Edoardo Charbon, a professor at EPFL’s School of Engineering (STI), was attending a workshop in Canada. It was there that he met Mohit Gupta, a fellow professor at the University of…

AI based early stage design support for efficient buildings

Sjonnie Boonstra developed AI techniques and optimization technology to support building designers in making influential decisions. Credit: Eindhoven University of Technology The construction, exploitation, and demolition of buildings make up for about 40% to 60% of the total energy and resource expenditure in Europe. It goes without saying that improving the material and energy efficiency in the built environment will be very beneficial with respect to societal challenges like climate change, environmental pollution, and resource depletion. With the help of…
