July 10, 2008[Ideas For Design] VHDL Code Offloads LED Blinking Task To A CPLD
An earlier Idea For Design (“Hardware-Based LED Blinking Control Eliminates Software Overhead,” Sept. 27, 2007, p. 52) described a very interesting way to offload the software overhead required for a microcontroller to drive LEDs that indicate operating states to the user. That article discussed the use of memory-mapped LED control registers, buffers, and a clock source, all used to blink an LED without burdening the microcontroller code with...

July 10, 2008[Embedded in Electronic Design] Make Or Buy: Module Mania
Make it low-power. Buying off-the-shelf parts to meet these criteria is still a challenge, but the latest crop of modules makes the job easier. Modules let designers develop custom configurations with minimum moving the design of the critical aspects of the system to the module vendors. This includes the processor and memory subsystem and usually most, if not all, of the peripheral interface. A carrier board typically contains connectors and...

July 10, 2008[Editorial] Show Videos Take Center Stage On ElectronicDesign.com
Most of you have probably noticed the influx of videos to electronicdesign.com over the past year or so. For the most part, these videos were shot at trade shows. Typically, a staff member at the show who knows something about video cameras hooks up with an editor to do video interviews. We shoot with a handheld, harddisk- based camera. When we get back to the office, a member...

July 10, 2008[Engineering Feature] Hardware/Software Co-Design Comes Of Age
There once was a time when system design was completely serial. Entire hardware platforms were designed, prototyped, debugged, and virtually completed before any software development began. Of course, such methodologies corresponded to the days of much broader market windows. The very idea of such a quaint approach is enough to make one snicker. Today, itâ??s quite different. Those market windows have narrowed to a sliver. Hardware development typically lags...

June 26, 2008[Lab Bench] Micros Find Their Way Into Blue-Ribbon Science Fair Projects
Held last month in Atlanta, the Intel ISEF 2008 brought together more than 1500 students from around the world as they presented their award-winning projects from state and regional science fairs. Individuals and teams competed in more than 17 categories, including a healthy showing in the Engineering: Electrical and Mechanical (EE) division. A number of students used development kits in their work. Chris King’s Electromagnetic Levitation: A Digital Control ...

June 26, 2008[Technology Report] FPGAs Pushing MCUs As The Platform Of Choice
Falling FPGA prices and ever-improving tools make FPGA development more palatable to designers who aren’t well versed in this arena. Likewise, the increased number of choices and improved sophistication of soft processor cores for FPGAs create new options for developers who would otherwise look only at stock, offthe- shelf microcontrollers. There are many reasons why designers should consider FPGAs as a development and deployment platform. Processors ...

June 19, 2008[Technology Report] Robots Finally Have That Personal Touch
Extending from the factory floor and into your living room, the personal robot’s time has arrived. These devices have pushed past uses as expensive and cute toys like Sony’s Aibo and into sophisticated and affordable products that perform a number of functions in and around the home. Allied Business Intelligence Research says that the personal robotics market, which includes robotic toys, educational robots, and task-based robots, will reach $15...

June 19, 2008[Technology Report] Get Ready For The Multimedia Mess
The setting sun is a pleasant sight while driving home. I’m listening to satellite radio and a call comes in. At my verbal request, the car’s media system switches off the music and answers the phone. I continue the conversation as I pull into the garage and switch the call to my home line as I exit the car. Continuing to chat, I move into a room with an HDTV and switch to video conferencing. The call ends and the radio program resumes from the point of...

June 19, 2008[Technology Report] Megatrends Of The Future Will Feed Off Industry Hype
Afaltering economy hasn’t slowed the electronics industry. According to many independent market research organizations and other sources, most market sectors will experience strong growth over the next five to 10 years. In fact, what has become a digital universe is expanding more rapidly than any original estimates. Updated projections based on research by IDC suggests that with a compound annual growth rate of almost 60%, the digital...

June 19, 2008[Technology Report] Robotics Give Doctors A Helping Hand
Advances in robotics technology are completely transforming today’s hospital operating rooms. With robot control and assistance, surgery for any kind of injury or ailment is faster, more accurate, and less invasive than ever before. Because robots help accelerate procedures, operations become safer. With conventional surgery, a surgeon performing an operation lasting several hours can become exhausted. As a result, the surgeon’s hand can be subject...

June 19, 2008[Technology Report] The Rats, Snakes, Insects, And Lobsters Of War
They run, crawl, slither, fly, and jump. They’re also robots. Fueled by funding from the Defense Advanced Research Projects Agency (DARPA) and other public and private organizations, researchers at labs nationwide are developing a new generation of military robots. Inspired by designs already perfected by nature, these robots are helping military units accomplish missions with less risk to soldiers and civilians. Joseph Ayers, principal...

[Design View / Design Solution] Correct-By-Construction Layout Generation And Modification
Physical design verification software typically identifies faults in physical layouts by finding design-rule-check (DRC) violations and layout-versus-schematic (LVS) mismatches after layout is complete. So-called “correct-by-construction” layout generation is a method for generating and modifying polygonal features during the layout construction process so that the layout satisfies both design-rule constraints and connectivity requirements.
