Your Cool Project Could Earn $500

May 9, 2012

I bet most engineers--as well as students and hobbyists--have pet projects they created either just for fun, or to meet a need at home.

Simplify FPGA Design and Test Projects

April 25, 2012

During the 2012 Design West conference and exhibition I talked with Frederic Leens, founder of Byte Paradigm, about a new approach to "instrument" and test designs within an FPGA.

Jack Tramiel, Computer Pioneer (1928--2012)

April 10, 2012

Commodore International founder Jack Tramiel died on April 8, 2012. According to his Wall Street Journal obituary, Tramiel (then known as Idek Tramielski) came to the US after WW II as a refugee and learned to service typewriters.

Tools and Chips Jump-Start Computer-Vision Applications

April 5, 2012

During the 2012 Embedded Systems Conference I learned more about hardware and software that will simplify creating new products that include vision capabilities so computers can interpret what cameras "see."

How Do You Know the Correct Time?

March 22, 2012

In September 2011, researchers at the CERN research labs in Geneva, Switzerland revealed neutrinos sent from Geneva to detectors in Gran Sasso, Italy might have traveled faster than light. Now, though, the 60-nanosecond discrepancy between the arrival of the neutrinos and the speed of light might come down to faulty timing. So how to do know what time it really is?

March Madness in the World of MCUs

March 15, 2012

Here in the USA basketball fans talk about "March Madness," the playoffs between various college teams that lead to a final championship. With the "Embedded World" show behind us and the Embedded Systems Conference (Design West) ahead, we're entitled to a bit of "Microcontroller Madness." The following information brings you news about five product introductions of interest to engineers and product designers who use MCUs.

Firmware Increases Security for Content Suppliers

March 8, 2012

We see increasing demands for high security in everything from consumer devices that handle financial information through to smart-grid electricity meters and set-top boxes that store proprietary entertainment files and programs. Even basic devices that update firmware remotely require secure communications.

A Universal Interface for Freescale's Background Debug Mode (BDM) MCUs

March 5, 2012

Although many microprocessor and microcontroller manufacturers use a JTAG-like interface to download code to flash memory and obtain debug information, not all JTAG pods work the same way.

Recycle Older PCs, Please

February 21, 2012

A few days ago I decided my old lab PC could no longer keep up with new programs that require a gigabyte or more of memory. I considered adding more memory to this venerable friend but decided to look for a replacement instead.
