The DSP/embedded market will go through a variety of changes in coming years as a plethora of changes in the electronics' market are forcing new developments in processing. The convergence of applications, the need for smaller sizes, the necessity of better energy efficiency, the demand for greater functionality, the concern for environmental friendliness and the growing trend toward medical monitoring at home — all of these factors are creating new opportunities and sizable challenges for the DSP market. Any one of these market pressures would be enough to drive innovation. All totaled, they will produce major changes in coming years.
Convergence is a big innovation driver. The iPhone is just the latest example of a small portable device with multiple formats. "In the 1990s, DSP was voice oriented, but now we're seeing multi formats," says Wayne Meyer, product line manager at Analog Devices Inc. "Now you have a convergence of applications. You have this cell phone that's like a small computer, media player and network device. Consumers have high expectations that it will play seamlessly and look great." For the processor, that means interfacing and talking with Ethernet while currently running the media player.
And the device has to be small. "We have to put more into a package," says Murugavel Raju, strategic marketing manager MSB430 at Texas Instruments. "That means higher densities and smaller geometries, more functionality." Energy management plays a big role if the device is running multiple functions. "You need to identify the peak energy demand and high energy use, so you need more processing and memory for energy metering," says Raju. He says the pressure for greater energy efficiency is coming from two fronts — the need to conserve battery power for portable devices and the growing concern over the environment. "We see more demand than we've seen in the past to extend battery life," says Raju. "But we also keep hearing about global warming everywhere. So, power consumption and the energy rating are becoming more important."
On another front, there is an emerging trend — which will become a major trend very soon — to move medical monitoring into the home. The desire for home-based equipment is coming from patients who don't want to sit in the hospital just to be monitored. It's also coming from the health care industry that doesn't want to keep patients in pricey rooms for monitoring alone. As the baby boom ages, this need will grow significantly. "Medical devices are moving into the home," says Raju. "That means more processing power in smaller devices."
A new battery design, which replaces lithium with abundant and low-cost elemental sulfur, is still in its nascent stages but shows real promise for giving batteries more energy potential.
PTC will offer a virtual desktop environment for its Creo product design applications, potentially freeing engineers to run them from remote desktops on a variety of operating systems and mobile devices.
The push to achieving more intelligent, integrated manufacturing is putting a strong focus on networking and connectivity as key enabling technologies.
Now that solar and wind harvesting technologies are a thriving market, researchers are seeking other environmentally related energy sources for which they can create harvesting devices.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
