Editor's Note

Bernard Cole Bernard Cole

Embedded systems developers and companies are already at work on the hardware and software building blocks and standards for 2013's consumer electronics products, even as the results of their ingenuity are now on retail shelves for this Christmas and designs for next year about to be highlighted at the Consumer Electronics Show in a few weeks.

Just rolling out are TI's power management ICs for solid state disks (SSDs), Broadcom's connected car devices , Atmel's new 32-bit AVR MCUs , Samsung's multicore powerd SSDs, Spreadtrum's $40 smartphone platform and Redpine's gigabit/second Wi-Fi design. Work on standards also continues with the Wireless Gigabit Alliance planning a 60 GHz wireless spec , Broadcom promoting the 802.11ac Wi-Fi standard, and the Khronos proposing a cross-platform computer vision spec .

My Editor's Top Picks this week: “How to use hover in a user interface , ” and “Taking advantage of the Cortex-M3's pre-emptive context switches . ” In addition there are design articles on Embedded.com that cover 40/100 G network design , traceablity tools for code development, and designing energy efficient gas/water meters.

Jack Ganssle's column “Anti-human apps” is about a bizarre and counter-productive use of mobile phones in moving vehicles, just as the U.S. National Transportation Safety Board has recommended banning the use of personal electronic devices (including mobile phones) while drivingany vehicle, except for emergencies.

How to use hover in a user interface

Hover sensing combines self and mutual capacitive sensing to create a mouseover-like functionality in a handheld device, including magnification and simplified text selection. Here are some of the capabilities and applications of hover technology in handheld devices.

Taking advantage of the Cortex-M3's pre-emptive context switches

In this article, Tyler Gilbert explains how programmers can make best use of the Arm Cortex-M3 (CM3) processor's hardware used for pre-emptive context switching as well as how to develop systems software routines that enable multi-tasking programs.

Keeping time on 40/100G networks with high-performance clocks

In this Product How-To article, James Wilson of Silicon Labs, describes the clocking requirements in the migration to next generation 10G/40G/100G networks and how the company's Si5374/Si5375 clock ICs can be used to satisfy the needs for any-frequency synthesis, jitter attenuation, clock generation and clock distribution.

Dealing with multi-Vt & multi-voltage domain timing/temperature inversion challenges

Scaling down to 40 nm and below imposes new challenges for physical design engineers relating to timing closure in their designs. But unlike earlier geometries at 90 nm and above, voltage and temperature (PVT) corners with the highest temperatures are no longer the worst locations for synthesis.

Cut the cost of code development with traceability tools

Requirements traceability matrices help developers manage change, reduce defects, and add process transparency for all levels of the staffing chain.

Squeezing more from less: How to design smart gas and water meters for the ultimate in energy efficiency

Electronic water and gas meters represent some of the most vexing low-power design challenges for embedded control systems requiring RF connectivity. The nature of these applications requires them to be battery powered as electricity is rarely provided at the point of service for gas or water utilities.

Public key cryptography and security certificates

This article explains public key cryptography and the role of security certificates and the way they are used by the secure protocols to provide ultimate security.

Radio susceptibility follows laws of physics

Adding complexity to enable RS protection for internal system parts is not a cost-effective strategy.

Lithium-imide bests Li-ion in mobile devices

Lithium-imide electrolyte chemistry clears conventional Li-ion's energy density and durability hurdles.

Sensors expand functions in mobile devices

New apps will tap sensor data on the user's context, habit and surroundings to infer what that user may need and offer assistance before it is requested.
