Magnetic RAM Meets the Power Basics

As CMOS size scale down, power challenges scale up. This tutorial shows why magnetic random access memory (MRAM) will help with power and integration needs.

Digital vs. Analog and the verification of power: Inductors

Power verification often meanders into talk of the di/dt voltage drop across inductors. A high level water cooler primer of such topics ensues.

What Powers the IoT?

By Stephan Ohr, Gartner Powering the Internet of Things (IoT) is a special challenge, says Gartner analyst Stephan Ohr, especially for the wireless sensor nodes (WSNs) that must collect and report data on their environmental states (temperature, pressure, humidity, vibration and the like). While the majority of WSNs will harness nearby power sources and batteries, [...]

Getting ARM’d for Innovation in x86 Modules is a Power Play

Chris A. Ciufo, Senior Editor An interview with Bob Burckle, Vice President, WinSystems discusses x86, ARM, and low power. WinSystems is one of those Tortoise and Hare kind of companies, often alternating between the two. The employee-owned Arlington, Texas company is progressive enough to literally rent out its parking lot for Dallas Cowboys tailgate parties [...]

Intersection for Success: 1Ghz at 2 watts

By John Blyler Mentor Graphics recently held their annual User-2-User conference in San Jose. The press was invited and – as usual – got along well with the users. The day’s events were kicked-off by Simon Bloch, VP and GM for Mentor’s Design and Synthesis Division, who began his brief introduction by highlighting the new [...]

Energy Scavenging And Storage Must Work Together

By John Blyler Designing embedded systems in energy-sensitive environments requires both attention to power details and a system-level view of overall energy architectures. Successful designers must embrace both perspectives. This isn’t easy. Most embedded hardware engineers are used to the fairly generous power offered by a wall socket or inexpensive traditional off-the-shelf batteries, where portability [...]

Linux Meets Low Power

By John Blyler LPD: How does Linux 6 work with low power. Do you turn off certain parts of the chip that aren’t being used? Ready: There’s an analogy to the boot. It’s very dependent upon the capability of the underlying hardware and the mechanisms that are available to you. There is dynamic power management-that [...]

Power Optimization Drives Embedded And Multicore Software

By John Blyler Max Domeika, senior software engineer in the Developer Products Division at Intel, sat down with LPE Consulting Editor John Blyler to talk about the growing importance – and intersection – of both the multicore and embedded markets. What follows are excerpts of that conversation. LPE: Intel’s software focus seems to be following [...]

Dual Core Embedded Processors Bring Benefits And Challenges

By John Blyler The embedded processor market has now fully embraced the multicore world with the recent introduction of the dual core option for Intel’s Atom devices. Dual-core embedded processors offer designers many new benefits while presenting new challenges. How will the multicore option affect low power designs, virtualization, and single-threaded legacy software? Will these [...]

Surface Models Focus Low-Power Parasitic Problems

Low-Power Engineering sat down with Raj Nair, founder of Anasim Corp. and co-author of a recent book on power integrity. What follows are excerpts of that conversation.
