Litho options falling behind process needs
Who killed high-index lithography, and was politics the cause? These questions remain for chipmakers looking for a route to next-gen manufacturing in a shifting lithography landscape.

SpringSoft works on global ambition
In its thrust to offer additional specialized EDA solutions, SpringSoft has completed its merger with Nova Software, and has announced the acquisition of four EDA and channel companies.

Beyond supercool: room-temperature THz lasers
A heterodyning method, cast in nonlinear materials, mixes two optical frequencies whose difference is the desired THz frequency, resulting in a room-temperature THz laser. This may act as scanner like x-rays safe for people and can detect hidden weapons, toxic materials present in the air or distinguish improvised explosive devices at a distance.

Hysteretic converters for multiple LED lighting
Hysteretic converters are used to drive LEDs in lamp replacement and emerging lighting applications. The ease of use and inherent stability of the topology make it a first choice for efficient inductive switching regulator solutions. The simple topology can be used in different configurations or other unintended external applications.

Comply with real-time network needs
Real-time middleware delivers the performance and functionality necessary to address the realities challenging the embedded industry.

Predicting real-world wireless performance
Scalability and the interaction of applications with each other have always made real-world wireless performance unpredictable in the lab. An additional challenge emerges with the introduction of 802.11n-complaint devices along with the existing a/b/g equipment.

The evolution of processor cores
Today's processor cores integrate more than 20 million transistors, supported by cache memories consuming billions of transistors and delivering almost 30,000 times more than the performance of Intel's 4004, the first ever microprocessor.

Technical Features
Partition multicores for embedded networking
Multicore processors are becoming mainstream in the embedded networking market. However, many architectural details need to be examined before decisions are made. One of the first decisions is how to partition the control plane, data plane, and services across multiple cores. (PDF file)

Avoid compliance test failure
HDMI products must pass the HDMI Compliance Test (HDMI CT). Based on the experiences of numerous pre-tests performed at ADI's HDMI CT lab, this article discusses the most common system design issues that cause products to fail the HDMI CT. It also analyzes specific case failures and offers solutions. (PDF file)

Boost battery performance with active charge-balancing
The benefits of Li-ion batteries can be realized only with a capable battery-management system. An active charge-balancing system offers significantly better performance than the conventional passive approach. The ingenious use of a relative simple transformer helps keep material costs low. (PDF file)

Save battery life with ambient light sensors
Applying ambient light sensing in conjunction with LED backlight driving can reduce power consumption significantly—while battery life increases. Advances in active solutions are exemplified by two examples, an ambient light sensor for a notebook PC and for a cellphone display. (PDF file)

Opinion
Channels feed design minds, fuel growth
Although the path has been checkered with periods of slow progress, India is now picking up steam.

Mesh nets survive catastrophes
The rapid growth of high-speed services and the increasing dependency on networks for mission-critical applications are driving the need for self-healing and fully meshed networks. And that type of network requires intelligence to make it aware of itself and its environment, incorporating the ability to react to any network event.


Interview
Transformed LSI shifts to implementation mode
In his first 24 months as president and CEO, Abhi Talwalkar was part of a radical restructuring in the manufacturing strategy of LSI Corp. He notes: "I claim the transformation is behind us, and we are in a mode of execution."
