For AI Hardware, Power Optimization Starts With Software And Ends At Silicon


Artificial intelligence (AI) processing hardware has emerged as a critical piece of today’s tech innovation. AI hardware architecture is very symmetric with large arrays of up to thousands of processing elements (tiles), leading to billion+ gate designs and huge power consumption. For example, the Tesla auto-pilot software stack consumes 72W of power, while the neural network accelerator cons... » read more

Power Management Becomes Top Issue Everywhere


Power management is becoming a bigger challenge across a wide variety of applications, from consumer products such as televisions and set-top-boxes to large data centers, where the cost of cooling server racks to offset the impact of thermal dissipation can be enormous. Several years ago, low-power design was largely relegated to mobile devices that were dependent on a battery. Since then, i... » read more

Differential Power Analysis


Authors Paul Kocher, Joshua Jaffe, and Benjamin Jun Cryptosystem designers frequently assume that secrets will be manipulated in closed, reliable computing environments. Unfortunately, actual computers and microchips leak information about the operations they process. This paper examines specific methods for analyzing power consumption measurements to and secret keys from tamper resistant d... » read more

Performance Analysis Of Electric Motors For EV Powertrains


Developing a battery EV powertrain is a complex systems problem. This technical paper examines the design and development of electric motors in an EV powertrain, showing how the different design choices — such as motor topology, winding type and cooling system — can be compared and evaluated considering their overall system impact. ANSYS Motor-CAD simulations can help engineers determine wh... » read more

Reducing Software Power


With the slowdown of Moore's Law, every decision made in the past must be re-examined to get more performance or lower power for a given function. So far, software has remained relatively unaffected, but it could be an untapped area for optimization and enable significant power reduction. The general consensus is that new applications such as artificial intelligence and machine learning, whe... » read more

Determining Where Power Analysis Matters Most


How much accuracy is required in every stage of power analysis is becoming a subject of debate, as engineering teams wrestle with a mix of new architectures, different use cases and increasing pressure to get designs out on time. The question isn't whether power is a critical factor in designs anymore. That is a given. It is now about the most efficient way to tackle those issues, as well as... » read more

Which Glitch Is Which?


Glitch is a commonly used term in modern vernacular, used to identify unexpected problems in everything from the space race, web site down time, or a crash of your latest mobile phone app. In electronics design glitch has a more specific meaning, referring to unnecessary signal transitions in a combinational circuit. Eliminating this extra switching activity can save power consumption, especial... » read more

Accurate Power Analysis Using Real Software Workloads


Over the last decade or so, power consumption has become a major issue in the design of many types of electronic products. Of course, power has always mattered for battery-operated devices, but the complexity of portable electronics and the size of the chips they contain have grown significantly. For plugged-in devices, from desktop computers to server racks in a data center, power plays a majo... » read more
