Power/Performance Bits: Oct. 25

Energy-harvesting floor Engineers at the University of Wisconsin-Madison developed a flooring material which can be used as a triboelectric nanogenerator to convert footsteps into electricity. The method uses wood pulp, a common waste material already often used in flooring. The pulp is partly make of cellulose nanofibers, which when chemically treated produce an electrical charge when th... » read more

Closing The Power Integrity Gap

Voltage drop has always been a significant challenge. As far back as 130nm, specialist tools were being used to ensure that enough local decoupling capacitance (decap) cells were inserted in addition to larger decaps implemented around the SoC. But advanced nodes are complicating matters and further increasing complexity. These technological challenges, which underlie the power, performance ... » read more

Power/Performance Bits: Oct. 18

Speeding up memory with T-rays Scientists at the Moscow Institute of Physics and Technology (MIPT), the University of Regensburg in Germany, Radboud University Nijmegen in the Netherlands, and Moscow Technological University proposed a way to improve the performance of memory through using T-waves, or terahertz radiation, as a means of resetting memory cells. This process is several thousand... » read more

Side-Channel Attacks Make Devices Vulnerable

As the world begins to take security more seriously, it becomes evident that a device is only as secure as its weakest component. No device can be made secure by protecting against a single kind of attack. Hypervisors add a layer of separation between tasks making sure that one task cannot steal secrets from another. Protection of the JTAG port is necessary to prevent access underneath the h... » read more

Lower Power Plus Better Performance

The tradeoff between power and performance is becoming less about one versus the other, and more about a dual benefit, as new computing and chip architectures begin rolling out. Neural networking, which is one of the hot buttons for any system that relies on lots of distributed sensors, is essential to get a true picture of what is happening around a car moving down the highway at 65 miles ... » read more

Why Do You Need Chip-Package-System Co-Design And Co-Analysis?

Whether it is the need for sustainable energy, or driving performance while keeping power at bay, or enabling safe and reliable operation of any electronic system, containment of electronic noise — power and signal noise is critical to all of the above. Other factors that impact safe and reliable operation are electromigration (EM), electromagnetic interference (EMI) and mechanical stress ena... » read more

How Software-Driven Tests Support Concurrent Power/Performance Analysis

There’s always been an intimate relationship between performance and power—and it’s one that is acutely affected by architecture. Architectural innovation can yield orders of magnitude improvements in performance/power metrics. For example, we’ve seen a growing popularity in multi-core and heterogeneous core systems with purpose-specific hardware accelerators. These configurations are o... » read more

Power Limits Of EDA

Power has become a major gating factor in semiconductor design. It is now the third factor in design optimization, along with performance, and is almost becoming more important than area. But there are limits to the amount of help that [getkc id="7" kc_name="EDA"] can provide with [getkc id="106" kc_name="power optimization"]. Power is not just an optimization problem. It is a design problem... » read more

Simplifying Software Separation With Real-Time Virtualization

Electronic systems are becoming more complex across multiple markets including automotive, industrial control and healthcare. Vehicles are beginning to drive themselves, industrial robots are becoming increasingly collaborative, and medical systems are automated to assist with surgery or deliver medication. This trend is not a new phenomenon. What was a high-end capability in the last generatio... » read more

From The Data Center To The Mobile Edge

At the heart of the Internet of Things is the complex interplay between the needs for both low power and high performance (LPHP), a perplexing challenge rooted in the de-facto bifurcation of the IoT itself. For example, lower power mobile devices, systems and lite endpoints make up the vast majority of forward-facing consumer infrastructure, while high-performance servers at the back end are ta... » read more
