Consumer electronics companies are asking the U.S. Federal Communications Commission (FCC) to mandate that their products be given access to applications and services running on the headend systems of cable TV providers.
A survey from the National Venture Capital Association predicts that venture capital dollars for clean technology will grow year but semiconductor funding will decline.
Technical challenges resulting from the latest WLAN specification, 802.11n, are significant. Serving multiple frequency bandwidths (2.4GHz and/or 5GHz) with multiple antennas, the devices used in 802.11n WLAN must be optimized for output power as well as size.
We've all heard the sizzle of e-paper displays, with their promise of wraparound advertising signs, wearable wrist monitors and e-newspapers that we fold or roll up and stick into our pockets. While the age of these gee-whiz products is not yet upon us, their enabling display technologies are on the move.
Configurable-core developer ARC International is refining a development platform that it says will change the way mobile multimedia systems are designed. ARC technologists described elements of the platform at the company's ConfigCon development conference held in California in December 2007.

Cable operators will introduce an external adapter this year that will let TiVo's CableCard-enabled digital video recorders access switched digital cable channels without an STB, according to TiVo and the National Cable and Telecommunications Association.
This article examines how two CMOS image sensor technology improvements are helping the automotive market improve the car's security and assistance and provide benefit for OEMs. It also discusses how they enable new possibilities in the automotive market and further integrate image sensors in cars.
A wide range of different car types is equipped with an electromechanical power steering system. But what kind of functionality is involved in implementing electronic power-assisted steering systems?
The PC and TV are converging. Between these extremes sits the STB. Powerful commercial motivations have already caused the PC and STB communities to make bold moves to claim this territory and be part of a three-way fight.
Technical Features
Today's new haptic interfaces can provide a more familiar, engaging, satisfying user experience for touch-activated controls. Fortunately, enabling a haptics system is now technologically simple and the electromechanical integration is well understood. (PDF file)
Significant improvements in the performance of signal processing functions in wireless systems can be realized by taking advantage of the flexibility of FPGA fabric and the embedded DSP blocks in current FPGA architectures for operations that can benefit from parallelism. (PDF file)
DDR3 SDRAM memory architectures support higher bandwidths with bus rates of 600Mbit/s to 1.6Gbit/s (300- to 800MHz), 1.5V operation for lower power, and higher densities of 2Gbits on a 90nm process. This faster, larger, and lower power per bit architecture is made possible by leveling the interface between a DDR3 SDRAM DIMM to an FPGA. (PDF file)
Achieving the desired brightness in mid-size LCD panel applications requires LED drivers to deliver a regulated current to the LEDs across all operating conditions. Typically, two types of LED driver topologies may be used: capacitive charge pumps and inductor-based switching regulators. This article focuses on the inductive converter LED driver circuits delivering between one to six watts of power to the LEDs. (PDF file)
Since its inception more than five years ago, PCIe technology has become the dominant interconnect protocol across virtually all market segments. There are many challenges involved in verifying device compliance and interoperability. Joshua Filliater of Denali discusses these challenges, and proposes the Denali Puresuite Sofwtare Solution as the answer to them.. (PDF file)
According to Yeo Siok Been of Avago Technologies, safety isolation is important for test and measurement equipment to ensure data integrity and to protect test operators. Isolators are selected based on its speed performance and most importantly, based on its insulation levels and ratings to meet required safety standards. (PDF file)
Synopsys' Chris Allsup explores in this article two DFT methodologies that take advantage of recent advances in ATPG technology to automate the generation of low-power manufacturing tests. (PDF file)
Opinion
Digital content is inevitably going to change the publishing industry, and it is leading to all sorts of questions.
Notes Scott Leif of Globalstor Data, technology advancements seem to proceed at unprecedented rates. However, while CPUs and processing technology appear to yield new products almost every month, storage interfaces lag behind.
Interview
Intel CEO Paul Otellini talks about surprising performance-per-watt gains from its hafnium transistors, the future of mobile and ultra-mobile devices and of course, all the big issues that affect Intel's channel.
Vital Signs
According to research firm NanoMarkets, revenues from products based on organic thin-film transistors and organic memories will reach $21.6 billion by 2015.
