Multiprocessor Communications

Part 1: Methods for Communicating

Communication is tricky no matter what, right? But when you have several processors involved, well, it just gets worse. Stuart begins this two-part series by looking at ways to get the messages between processors on a single backplane.

HTML Developing a Custom Integrated Processor

Analyzing the Price/Performance Tradeoff

If standard processor configurations aren't quite what you need, consider a processor-independent core. Joe and Sylvia bring to your doorstep a customizable core, so you can manipulate valuable variables in the price/performance equation.

PDF, PDF HTML, HTML Using Java in Embedded Systems

If you're set on putting some desktop-Java functionality into an embedded system, chances are that you've hadsome sleepless nights. No more! That's what Vladimir and Mike promise if you'll consider the available alternatives.


Hank Wallace

Music at Your Fingertips

Guitar Effects via Remote Control

Hank loves to play guitar, and like many guitarists, he thinks that using pedals to control the effects is too restrictive. What's a stage-raging musician to do? As an embedded-systems designer, Hank opted to put the music in the hands of the artist.

In the Face of Medusa, Part 1: Developing Reliable Control

Fred believes any monocomplex embedded system will turn to stone when faced with this NASA ground support unit's host of pumps, valves, and cameras. So, he sent up PicStic to meed the challenge. Has Medusa met her match?


Gordon Dick

HTML, HTML The PCL3013 Step/Servo Motor Controller in Action

If you need a high-performance step/servo motor controller, check in with Gordon. Along with its unique approach to program memory (data is written to preregisters), the PCL3013 offers so many interesting features, you won't want to miss out.


Joe DiBartolomeo


TPU, Part 1: A Coprocessor for Timing Functions

Timing is everything, moreso for embedded systems. So we don't lag behind, Joe provides us with the basics of the timer/counter functions found on various popular microcontrollers before introducing the time processor unit.


Jeff Bachiochi

From the Bench

Can You Feel the Beat?

With a son taking drum lessons, it's no suprise that Jeff wants to create a metronome. And small wonder that he needs an accurate timebase for it! Listen in to learn how a new crystal oscillator helps out.
