[Product Innovation]
PIC MCU Grows To 16 Bits, Adds A DSP
Core embedded applications increasingly demand more processing power, higher math capability, and faster processors. Driving these needs is a shift to more processing power to replace expensive sensors, to achieve closer motor control, and to... — Ray Weiss

[Design Application]
Co-Simulation Predicts How Programmable Devices Will Function On A Circuit Board
For some time, designing and testing PLDs has taken place primarily in the world of hardware description language (HDL). Of course, most PLD are eventually mounted on a pc board of some sort when they're deployed in the real world. Traditionally,... — Contributing Author

[Ideas For Design]
Decompensated Op-Amp Gain Is Adjustable From Zero To Open-Loop
Over three decades ago, the internally frequency-compensated, monolithic op amp was introduced. Since then, many of these devices have been made available in two variations. While both versions are designed to maintain the same dc parameters, they... — W. Stephen Woodward

[Ideas For Design]
Latching Overvoltage Indicator Handles Large Overloads
This overvoltage detector can be connected to any dc power source (Fig. 1). Its purpose is to provide a visual indication of when the voltage exceeds a preset value, which may range from around 3 V... — Contributing Author

[Editorial]
Lessons Learned And Lessons Not Learned
The economic ups and (recent) downs keep us constantly on our toes, forever fending off challenges to lower a product's cost, develop a new generation of products, or just make a product more attractive in a tough market. Over the past 30 years or... — Dave Bursky

[Pease Porridge]
What's All This Tee Network Stuff, Anyhow?
A few dozen years ago, somebody asked me how to compute the transform between a TEE (or WYE) of resistors and the DELTA of resistors shown in the figure. I did all of the calculations... — Bob Pease

[Viewpoint]
SoCs And SiPs Bring Dramatic Changes To The Embedded World
Engineers have been designing em-bedded systems since Intel introduced the 4004 in 1971. So why is the 38th Design Automation Conference (DAC) placing a special emphasis on embedded systems in 2001? What's new is the mainstreaming of... — Contributing Author

[Editor's Notebook]
Home Networking: What, When, And How It Can Bloom
The idea of home networking isn't new. In fact, I had my first home network in 1995, and so did others. But it's even easier today because the technology and the products are here. What's lacking is the market. It will take three major breakthroughs... — Louis E. Frenzel

[Conference Preview]
DAC Follows Industry's Lead And Takes Embedded Tack
Embedded systems are everywhere, or hadn't you noticed? The organizers of the Design Automation Conference (DAC) certainly have. As a result, this year's 38th DAC (June 18-22) will take on a decidedly embedded flavor as the EDA industry's annual... — David Maliniak

[Embedded in Electronic Design]
Breaking Rules
Downsizing, reduced markets, layoffs, and drops in stock prices dominate today's news. Companies have a choice—they can either ride the curve down, or try to innovate and sell their way up. Bad times call for good engineering and... — Ray Weiss

[Embedded in Electronic Design]
StarFabric: A Switch Fabric For Today
Function Switch fabric: multiple end nodes, switch nodes Also PCI switch fabric (100% PCI compatible) End nodes: bridge between fabric, local buses Switch nodes: intermediate... — Ray Weiss

[Embedded in Electronic Design]
Open Services Initiative: OSGi Links Devices And Clients
Embedded-system developers need to deliver robust end-to-end solutions between clients and devices, but this task can be hampered by the lack of standard interfaces between services. The Open Services Gateway Initiative (OSGi) is developing an open... — William Wong

[Embedded in Electronic Design]
Software Directory: Operating-System Series
Microsoft Windows CE 3.0 Windows CE does more than windows. This 32-bit operating system (OS) works equally well in deeply embedded applications such as Internet appliances and handheld devices such as the Pocket... — William Wong

Benefits Of Man-In-Space Program I always enjoy your articles, but I somewhat disagree with "Man-In-Space Is An Ambition Whose Time Has Passed" [April 2, p. 152] and want to point out something that you may... — Various

[40 Years Ago]
Disks Race For "Fastest With Mostest"
A new disk file has joined the race to provide vast amounts of digital storage with very fast access times. The newcomer is the IBM 1301 storage unit, the fourth important development in disk files in less than a year. It is IBM's dramatic advance... — Steve Scrupski

[40 Years Ago]
Molecular Digital Computer In Design At Westinghouse
A miniature digital computer that would use functional blocks is reportedly under development at Westinghouse Electric Corp.'s Air Arm Div., Baltimore. To be ready for testing in about 18 months, the computer is planned to have an expandable... — Steve Scrupski

Optical Wireless Technology Bumps LANs To 100 Mbits/s
There's a new way to get 100-Mbit/s speeds in a LAN: optical wireless. Wireless LANs certainly aren't new, but they've never even come close to replacing the old-style wired LAN. The new 802.11b Ethernet wireless LAN standard shows great promise for... — Louis E. Frenzel
