Documenting your Agile embedded design

Editor's Note

There is good news this week for many segments of the electronics and embedded systems markets. First, U.S. chip firms beat out international rivals in terms of total IC shipments and Intel achieved #1 in shipments over competitors worldwide, significantly ahead of second place Samsung, which had been taking market share from Intel.

That does not seem to have bothered Samsung, which has just announced a 2 GHz dual-core ARM A15 processor, an 8-Gbit non-volatile phase change memory device, and an integrated sensor-in-pixel design . The good news for Samsung – and all of us – is that its introductions could change the way touch screen LCD and mobile devices are designed.

More good news in the mobile device segment – at least for consumers – is that there is a sub-$100 Tablet computer from a Chinese firm in Taiwan. The bad news for Arm and its partners is that it is built with an MIPS processor.

Despite the momentum for all things Android, Jack Ganssle's newest column, “Android users get screwed , ” gives the platform's vendors failing grades for their poor software support. Apple's support for the iPad gets an A+. Another winner this week is Amazon, whose Kindle Fire has taken over the lead in Android-based Tablet computer sales and is second in sales only to Apple's iPad. In the process, Amazon may have created a new business model for success in this highly competitive market segment.

If you would like to know what the future holds for how we will interact with our mobile computing devices as well as a myriad of embedded systems, be sure to read two features from the December ESD Magazine: “Gesture recognition: first step toward 3D UIs?” and “The challenges of multi-touch gesture interfaces.

Gesture recognition–first step toward 3D UIs?

Gesture recognition is the first step to fully 3D interaction with computing devices. The authors outline the challenges and techniques to overcome them in embedded systems.

The challenges of multi-touch gesture interfaces

The key to understanding multi-touch touch panels is to realize that a touch is not the same thing as a mouse click.

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.

Defining the 4G PHY architecture design challenges

As with most emerging technologies, design challenges for LTE-A abound, particularly when it comes to the physical layer (PHY) architecture development. Addressing these challenges remains critical to the successful development and deployment of LTE-A designs.

Component integration paces EV, hybrid power electronics efficiency

To achieve maximum power density, electric losses and thermal resistances must be kept to a minimum—thus maximum component integration is required.

Generate dual supply rails using a high-efficiency SEPIC-Ćuk converter

Understand how this converter topology can provide a bipolar supply with good performance

Audio converter subsystem design in the 21st century – Part 1: Overview

Most audio converter subsystems perform below the potential of their chosen data converter. Here, Ian Dennis of Prism Sound examines why that might be, and offers tips on how to achieve optimum audio converter performance.

Primary-Side-Control with Active PFC Offline LED Controller

Designing a successful LED light depends on adapting what is essentially a DC device to run using the AC mains signal—which typically requires more circuitry than incandescent bulbs.

Voltage-mode CRM PFC for lighting offers higher efficiency, improves reliability

Topology is backwards compatible with older current-mode designs.

Evaluating PCB layout tools: A board developer's perspective

A look at some popular printed circuit board layout tools by an experienced PCB designer, who evaluates the strengths and weaknesses of some of them and provides tips on some work-arounds as well as features he thinks should be in the perfect PCB tool.

Embedding HPC: A rocket in your pocket

New embedded processors, single-board computers, and software development tools are enabling super-computing-like applications on embedded systems. Here are a few recent advances in HPC for embedded systems.
