The auto industry has fully recovered to pre-recession highs of 2007—at least in one segment.

The germ for this contest came from when Alda, as a curious 11 year old, asked his teacher, What is a flame?” Her reply, It’s oxidation” was understandably less than inspiring to the young lad. As we all know, Alda grew up to, among many other things, entertain us for 11 years as Hawkeye Pierce in M*A*S*H. What many people don’t know is that he grew up to also have a passion for explaining science to children.

When Mara Cruz, Online Art Director on UBM Electronics and a contributor to Innovation Generation , told me about The Flame Challenge , our first reaction was, Why can’t we do the same thing for engineering?” And a new contest was born.

We know there are plenty of budding engineers out there eager to learn. Often the adults they meet inspire them, but sometimes adults – with our too-large words and obtuse ways – inadvertently turn kids off. The goal of the Define Yourself” contest is to counteract that by challenging our readers to explain engineering terms to kids in a way that conveys to them your passion for the field.

So now, we’d like to challenge you the readers of EE Life to define Engineer.” After verifying the answers for accuracy, we’ll take the best definitions and hand them over to the student readers of Innovation Generation (EE Times 's science, technology, engineering, and math education site). Our precocious bunch of budding engineers will vote on the definition that they find the most understanding and inspirational.  

Enter your definition for Engineer” into the comments field, below.

In less than two weeks, we’ll be unpacking boxes of old iPods and iPhones and setting them out for kids to tear apart. That’s the iPod Autopsy in a nutshell, and it’s just one of the fun activities planned for the Innovation Generation (iGEN) booth in the USA Science & Engineering Festival coming to the Walter E. Washington Convention Center, Washington, DC, aApril 28 and 29.

The USA Science & Engineering Festival is the country’s only national science festival, and was developed to increase public awareness of the importance of science and to encourage youth to pursue careers in science and engineering by celebrating science in much the same way as we celebrate Hollywood celebrities, professional athletes and pop stars. The USA Science & Engineering Festival is a grassroots collaboration of over 500 of the United States' leading science and engineering organizations. For more information on the USA Science & Engineering Festival, please visit the Festival website.

The Festival Expo — with its fascinating array of hands-on exhibits and stage shows, coupled with up-close interaction with renowned innovators, and top researchers and celebrities in science and engineering — has rapidly evolved into a must-see event for families, students and others across the country and globe. A free weekend event, the Expo culminates a month-long series of Festival events taking place in April throughout the nation and in various foreign countries to encourage young students in STEM (science, technology, engineering and mathematics).

The iPod Autopsy, a highlight of the EE Times / Innovation Generation booth, will be run by Kyle Wiens from iFixit.com and Allan Yogasingam from UBM’s TechInsights . Kyle and Allen will be giving demonstrations of the inner workings of these amazing gadgets and then letting the kids at the Expo take apart and reassemble a real iPod or iPhone so they can see firsthand how it works.

The process of configuring SoC platforms goes far beyond simply reconfiguring a processor core to support additional instructions, or configuring a hardware core to support more communication modes. It includes the overall system interaction of functions running on different architectural implementation alternatives.

What configuration options might exist in a typical multimedia SoC integration platform? It will have an RISC processor to run the basic control software. This processor will be connected through a memory interface to external memories and several peripherals will carry dedicated hardware acceleration functionality and provide the interface to the external world.

For speed, performance or energy consumption reasons the bus might be partitioned using a bus bridge. Depending on the SoC design functionality, some configurations of the SoC platform might require two or more processors. Crossover bridges may be required between the local buses serving the processors, which can be peripherals talking to two or more buses. Some of the VCs, such as dedicated hardware accelerators, may require very high memory bandwidth. This leads to the introduction of a dedicated memory bus, which may make it necessary to use direct memory access and direct channels between peripheral components.

Even the small number of considerations mentioned above easily reach 50 different configurations if we take into account different processor speeds, bus width, RTOS, scheduling, etc. Previously, those decisions have been based on designer experience, ad hoc techniques and, often, gut feeling. The moment of truth was the actual big bang” test-connecting the hardware and software implementation models using co-verification tools. To come to the realization at this point that a function in software really should have been implemented in hardware can have serious consequences for a project.

Let's look at a real-life example. Three years ago, in an MPEG-2 design, the simulation of a single PAL frame at the RTL level took approximately 12 hours. Since then, increasing simulator efficiency has been paralleled with ever-more complex SoC designs that are now connected to an instruction set simulator (ISS) running 100,000 to 500,000 instructions per second. A possible synchronization problem between video and audio (to be dealt with by a central system control function) occurs after many frames (say, 40)-at least 480 hours in the example above.
