Editor's Note

According to International Data Corp.(IDC), smartphones and tablets are driving mobile CPU growth . Recent market activity seems to bear this out, with a new mobile iPhone 4s rolling out from Apple, Google showing off its Android 4.0 mobile operating environment, and Samsung ramping up production on Apple's A6 quad-core processor to meet market demands for Apple's next generation of iPhones.

Paradoxically, despite record sales on Macintoshes and iPads, Apple's quarterly sales have come up short , due mainly to a softening in the smartphone market. And despite Intel Q3 sales up 29 percent over last year at $14 billion, the one disappointing segment was the company's Atom processor chipset targeted at mobile platforms, sales for which were down 32 percent.

It is at times like these that I reread a recent column by Jack Ganssle on “Hope and Horror , ” in which he advises a rigorously skeptical attitude towards most market analyst reports. I also recommend reading Jack's newest column on “Android: now or later ,” in which he tries to get to the bottom of the overwhelming popularity of Android mobile platform classes at the recent Fall ESC, despite the fact that it is totally inappropriate for most embedded systems designs. I think he would appreciate your feedback.

Capacitive sensing expands to multi-touch all-point sensing in automotive apps

This article covers the basics of capacitive sensing and the evolution of touch sensing technology in automotive environments.

Options for simulating wideband signals

The need to take baseband signals and modulate them onto higher frequency carriers is fundamental for both the design and evaluation of communication and radar systems. How do we go about modulating and then upconverting wideband signals to their operational carrier frequencies for simulation?

Microwatt charge pump boosts 1V to 1.8V at 90% efficiency

Design provides “always on” standby power for microcontrollers

Integrated tools streamline low-energy MCU development

Microcontroller development is a complex process. Each individual model is different, with its own set of interfaces and control registers. Low-energy MCUs extend the range of options with a variety of power-down modes and in some cases intelligent I/O engines to offload some of the processing burden from the processor core.
