Editor's Note
With Gartner expecting IC capital expenditures to decline 20% in 2012, and companies such as Freescale lowering 3Q sales estimates , it might be useful to pay close attention to the strategies that microprocessor and microcontroller suppliers are adopting in the face of a souring economy.
In “A three-horn dilemma with a three prong solution, ” Yasushi Akao, president of Renesas, says the plan is to “become a much slimmer company by 2012,” with a continued focus on its MCU business. In “Microchip's strategy in a weak economy,” Ganesh Moorthy, the MCU vendor's COO, outlines what the company is doing – primarily to not panic (per Hitchhiker's Guide To The Galaxy? ) and “focus on the things we can control .”
Moorthy's strategy seems to be the preferred one in the embedded market, with Freescale introducing an ultalow power smart radio , Unity rolling out a terabit memory architecture , MIPS and eSilicon taping out a 28 nm MPU cluster SoC, and startup Memoir offering memory IP core for network and multicore processors.
At Apple, though, the attitude seems to be “Downturn? What downturn?” as it rolls out its newest smartphone, the iPhone 4S. For some perspective on this introduction, be sure to read “Apple iPhone 4S: Beginning of the end?” in which Rick Merritt speculates on whether the growing dominance of the open source Android smartphone platform is a sign that Steve Job's company has finally run out of luck.
For a reminder about where all this came from, be sure to read “From light bulbs to computers ,” the second part in Jack Ganssle's series of columns celebrating the 40th anniversary of the microprocessor.

An efficient pad ring design to circumvent test probe limitations and meet requirements
In this article the authors address the problems faced in the testing of advanced SoCs. They describe some pad ring design techniques developers can use to allow die probe testers to operate in parallel fashion but without wasting die size.
Taking on the 0.3 mm ultra-fine pitch device challenge in PCB design
To deal with the printed circuit board design challenges of nextgen nanometer circuits and the demanding packaging constraints of small footprint mobile & embedded apps, Nexlogic's Michael Yu thinks the answer boils down to carefully crafted PCB design, fabrication, and assembly guidelines.
Minimizing yield fallout by avoiding over and under at-speed testing
In this article the authors discuss the problems associated with SoC at-speed testing such as over-testing and under-testing, which affect yield, and provide suggestions on how to overcome them.
Validating your GNU platform toolchain: tips and techniques
Open-source tools for your open-source Android/Linux platform.
Understanding Android's strengths and weaknesses
Here are techniques for exploiting Android's strengths and managing its limitations, especially in hard real-time, mission-critical systems.
The importance of sustainability in design engineering
Carbon, energy, water, and waste data embedded during the design phase has more to it than simply good environmental stewardship. Design engineers can use global standards and trends in sustainability to get electronics projects off the ground, and drive accelerated development.
Reducing Turnaround Time with Hierarchical Timing Analysis
STA is a key task during chip design that directly impacts design cycle time. Hierarchical techniques are used to break down design complexity into manageable units…
Multi-gigabit data link aggregation for next-generation systems
Understand the virtues and necessity of aggregated links in leading-edge systems, and some implementation tradeoffs.
10GBase-T Technology Revisited
This article will explore the basic operation of a 10GBase-T transceiver and the inherent advantages of 10GBase-T technology as compared to alternatives, such as optical fiber and coaxial copper.
Advantages of SONOS memory for embedded flash technology
This article makes the case for the use of 65nm SONOS technology for embedded flash applications.
How femtocells will solve data capacity
Data traffic is overwhelming mobile operator's networks reports Steven Brightfield of Qualcomm CDMA Technologies. Projections from major operators confirm this trend, with recent reports ranging from data capacity doubling every 3 months (KT/Korea) to 12 months (Vodafone).
Hunting noise sources in wireless embedded systems
In an embedded system design, especially one bringing together high-speed RF and serial or parallel components, noise can come from almost anywhere. Without clues as to the sources of noise, debugging can be time consuming and tedious. With a mixed domain oscilloscope (MDO) however, engineers can see noise sources like spectrum splatter during turn-on, drain voltage power supply coupling, or other cross-coupled emission events and correlate these events to specific logic states or analog circuit conditions. This article discusses techniques for finding unintentional noise sources as well as using automatic markers to look for emissions (harmonic related or other).
