A Digital Filtering Primer

You'll often find articles written about digital filters, how they work, and how to design them. But, how often do they approach the subject from a pratical standpoint? Tom shares some design tips from the trenches.


David Prutchi

Spectral Analysis

FFTs and Beyond

Digital signal processors are often used for doing spectral analysis of incoming waveforms, but the old standby FFT can have its downside in the real world. Find out what to watch for in your next design.



Alan Land

Introduction to Doremi-DSP

It may have taken Julie Andrews to make the song famous, but she likely never would have guessed that "DO-RE-MI-fa-sol-la-ti-do" would inspire a name for a new DSP technique. It goes one step beyond the old FFT.

Fast-scaling Routine for Floating-point RISC and DSP Processors

While the bulk of many applications can be written in a high-level language, some situations require the speed of hand-tuned, special-purpose assembly code. Check out one example.

Journey to the Protected Land: Base Camp at 1 Megabyte

While there are protected-mode operating systems already available, rolling your own is the best way to learn. Ed skips the specialized tools to show that real-mode tools can be used just as effectively to generate PM code.

Does Anyone Have the Time?: A Comparison of Real-time Clocks

Every chip manufacturer seems to feel they can do the other guy one better when it comes to clock-calendar chips. Jeff takes a quick survey of the market and compares what's available today.

Silicon Update

Hot Chips VI: Image Compression, 3D, and RISC

Tom turns up the heat with a visit to the latest Hot Chips show. Video and graphics are the hot topics these days, as shown by the latest round of silicon.

Heavy Duty Hammers: Beef up the 8052 with the DS87C520

John's been spending time talking about the new DS80C320 processor, but what happens when you want a true high-speed microcontroller with onboard ROM? Bring on the DS87C520.
