I agree, Liz. The memory will be especially important for motor control applications.

Thanks for that perspective, Lou. These applications are demanding more memory and more easy access to it. I think memory-rich components will continue to be a trend for some time.

Thanks again, naperlou. Great info. It took a lot longer for 8-bit to drop to this point than the experts predicted. And still, it's far from dead.

Well, Chuck, the answer to that (8-bit CPUs) is 12%.  Before you ask, the numbers for 16 and 32-bit processors are 14% abd 8% respectively.  Both 8 and 16-bit are trending down from 5 years ago.  32 and 64-bit are trending up.  As the new 64-bit Power and ARM architectures get implemented by chip manufacturers, I expect they will grow more. 

The 32-bit ARM can be had in a very small fiorm factor.  I have one eval board with a high pin count 32-bit ARM CORTEX-M4 MCU SoC with a small ARM Cortex-M0 as a debugger interface.

Thanks for that info, naperlou. I wouldn't have guessed that 32-bit is at 63%. For many years, 8-bit held onto a big chuck of the market, while experts predicted it would fall by the wayside. I'd like to see where 8-bit came in on the EE Times study.

As systems become "smarter" the microcontrollers that run them need to be more powerful.  We already have a preponderence of 32-bit processors being used.  The EETimes Embedded Market Study shows that 63% of designs use 32-bit processors.  The vast majority of these use the ARM architecture.  More memory allows for more buffering and more complex algorithms.

Memory access improved
Elizabeth M   8/7/2013 7:54:53 AM
All the memory in the world is nothing on an MCU if it can't be accessed easily by a device, and Toshiba is trying to improve this situation with its new TMPM36BF10FG, which provides faster access to the chip's onboard memory. This allows for higher performance applications and is a good fit for data-processing-intensive applicaitons.

The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
At Medical Design & Manufacturing Midwest, Joe Wascow told Design News how Optimal Design prototyped a machine that captures the wing-beat of a duck.
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
