One of the reasons that temperature and power dissipation have become such large issues is that increased speed has increased the number of operations per second, while the power dissipation per operation has not dropped that much. The reason for the speed increase can be partly shown to be inefficient software, more commonly called "bloatware". Of course it is easier and faster to write, but poorly written code wastes power. The excuse for allowing code that is not efficient has been that memory and processing power were so cheap that they could make up for the poor code. Now it is becoming clear that this is a bad choice, since the devices have become so very small, leading to much higher power densities.
One means of reducing the heat load, then, would be to use better code, and slow down the processor a bit. Of course this will require a level of programming skill that is not very common, and also a reduction in the number of useles features that seem to be everywhere. But it is the one solution that does not wind up challenging the basic laws of physics.
Airborne is the first sector we'll see, with mini-drones already requiring DSP capability in a vastly shrunken space. Automotive is always a field ripe for more dashboard integration, but I'd expect medical electronics to increase demands fairly quickly. Medical record digitization has accelerated now that hospitals are accepting tablets as a better alternative than laptops, and this will drive an overall move to get patient data acquisition into handheld platforms whenever and wherever possible.
What's your sense of the thermal and packaging challenge in the embedded space as MCU vendors pack more and faster cores (dual core) into what used to be fairly standardized and not all that cutting edge parts?
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
