Usage Models Driving Data Center Architecture Changes


Data center architectures are undergoing a significant change, fueled by more data and much greater usage from remote locations. Part of this shift involves the need to move some processing closer to the various memory hierarchies, from SRAM to DRAM to storage. There is more data to process, and it takes less energy and time to process that data in place. But workloads also are being distrib... » read more

Is Computing Facing An Energy Crisis?


Is the end near? If the topic is energy efficiency gains in computing, the answer depends on whom you ask. The steady increase in performance per watt over the decades has been one of the most important drivers in our industry. Last year I was thumbing through a neighbor’s 1967 Motorola IC catalog that featured such space age wonders as a small control chip of the sort that went into th... » read more

Power Models For Machine Learning


AI and machine learning are being designed into just about everything, but the chip industry lacks sufficient tools to gauge how much power and energy an algorithm is using when it runs on a particular hardware platform. The missing information is a serious limiter for energy-sensitive devices. As the old maxim goes, you can't optimize what you can't measure. Today, the focus is on functiona... » read more

Low Power Still Leads, But Energy Emerges As Future Focus


In 2021 and beyond, chips used in smartphones, digital appliances, and nearly all major applications will need to go on a diet. As the amount of data being generated continues to swell, more processors are being added everywhere to sift through that data to determine what's useful, what isn't, and how to distribute it. All of that uses power, and not all of it is being done as efficiently as... » read more

Artificial Intelligence For Sustainable And Energy Efficient Buildings


According to the goals of Europe’s green deal missions, the continent strives for becoming carbon neutral by 2050. Since buildings are a major contributor to the overall consumption of energy, improving their energy efficiency can be a key to a more sustainable and greener Europe. On the way towards zero-emission buildings, several challenges have to be met: In modern energy systems, several ... » read more

Energy-Efficient AI


Carlos Maciàn, senior director of innovation for eSilicon EMEA, talks about how to improve the efficiency of AI operations by focusing on the individual operations, including data transport, computation and memory. https://youtu.be/A3p_w7ENefs » read more

Saving Energy In The Fab


It’s not an exaggeration to say that integrated circuits are a critical component of any effort to reduce global carbon dioxide emissions. The most efficient engines depend on microcontrollers to optimize fuel consumption. Global shipping uses sophisticated simulators for load balancing and route planning. Computing power that once needed room-sized cooling units now fits in a battery-powered... » read more

One-On-One: Dark Silicon


Professor Michael Taylor’s research group at UC San Diego is studying ways to exploit dark silicon to optimize circuit designs for energy efficiency. He spoke with Semiconductor Engineering about the post-Dennard scaling regime, energy efficiency from integrated circuits all the way up to data centers, and how the manufacturing side can help. What follows are excerpts of that conversation. (F... » read more

How Long Will Your Battery Last?


Designing an IP block or memory subsystem to fit within a power budget is essential for building energy efficiency into hardware and software. There's only one catch—it's meaningless to the end customer. Twenty years ago this was a pretty straightforward formula. If you used a device consistently, whether it was a computer or a calculator or an electric motor, then you would burn up X numb... » read more

Making Software Better


Gauging the energy efficiency of software is a difficult task. There are many types of software, from embedded code all the way up to software that controls various modes of operation to downloaded applications. Some software interacts with other software, while other software works independently. And some works better on one SoC configuration than another, or on one iteration of an operating s... » read more
