In this sort of scenario, the growing Wi-Fi network can be used parasitically” by adding Wi-Fi capability to the RFID chip. Another option is zonal RFID arrays embedded in ceilings.

FreeRTOS, RTEMS, and eCOS are just a few of *many* kernels with free usage and available source code.

The fact that Micrium now sells (for a good buck) things like a GUI, USB shim, Filesystem, etc… indicate that the market for their kernel is softening, similar to the survey results.

Hello,

Your findings about the decrease in OSS or Linux share are confusing. In big yellow press letters you write Linux disillusionment” and in your graphs below (Figure 6 and 7) you seem to proof the opposite.

Somehow you seemed to mix up OSS, Linux, Linux with commercial support, and commercial OS. Simply adding a few numbers gives me different results.

I like your survey. However, I believe the definition of an embedded system” is becoming far too vague. The distribution of operating systems is spread across a large field. Some support Virtual Memory and are designed for it, others are specifically for systems with no VM.

I'll bet if the first question you asked in the survey was Does your product have or make use of an MMU?” you would find a large split in the results. With most people using an OS for MMU based systems. Lets face it if you have an MMU you must have a lot of memory, and therefore your embedded system” is really more of a very small version of my desktop. Which is what a PDA phone really is now.

Prices eroded because they were willing to sell at any price to keep their factories open,” Spears added.

Subsequently, any new capacity in the pipeline at U.S. capacitor makers was put to a stop. But by early last year, capacitor consumption in the Japanese consumer- electronics market increased.

So the Japanese capacitor makers turned their backs on the commitments made to U.S. and European [OEMs] and started supplying Japan again,” Spears explained. That created an instant shortage at the same time of the wireless and telecom boom.”

Prices are up, up, and away

Meanwhile, prices continue to climb. Prices of the more common types of MLCCs have risen to 1.5 cents, up from 0.5 to 1 cent a year ago, Spears said. Tantalums have climbed to about 15 cents, from about a dime a year ago.
