Welcome to the changing face of digital signal processing
Signal Processing DesignLine Blog 7/29/2010 3 comments
The world of DSP has undergone a massive shift, from the use of well-defined, math-oriented architectures to a more holistic approach that looks at the problem and selects any combination of available architectures, DSP, RISC or FPGA, to solve it. We've changed our approach too, to help you navigate these new waters more effectively.
Life, attachments and how to smash a CRT

It’s funny how you never realize how much something has woven itself into the fabric of your life until you sit down and try and figure out the best way to smash it to smithereens.
TI's multicore SoC: Right notes, ringing hollow
Signal Processing DesignLine Blog 2/17/2010 Post a comment
While the new multicore system on chip (SoC) signal-processing architecture announced by Texas Instruments this week at Mobile World Congress hits all the right notes with respect to what's needed in next-generation basestation designs, it rings a bit hollow given how sketchy the architectural details remain when contrasted with more 'real' announcements from the likes of Freescale.
The SoC in 2020: Advances to redefine how we live
Signal Processing DesignLine Blog 12/3/2009 Post a comment
In this fourth installment of TI's 2020 Vision series, Senior Fellow Bill Witowsky (retired) explains why the inherent functionality of future high-performance SoCs will be defined by software in order to facilitate the repurposing required to offset their development costs.
Magic microphone: All smoke, no mirrors
Signal Processing DesignLine Blog 11/19/2009 1 comment
To get around the dynamic range issues of current microphone pickups, Schwartz Engineering and Design has devised a laser-based pickup that detects voice-induced 'distortions' in a flowing stream of smoke and that then relies on proprietary digital signal processing to translate those distortions into audio. And it works!
The path to money in medical systems design
Signal Processing DesignLine Blog 9/21/2009 Post a comment
Between government stimulus packages, an aging population, exploding healthcare costs and increasing need for better remote diagnostics, it's understandable that engineers looking for the next big opportunity would look up and cry: "Thars gold in them thar [medical] hills." But not so fast.
Chip vendors making VCs redundant
Signal Processing DesignLine Blog 9/11/2009 Post a comment
The next time you have a great idea for an end product, you should look at bit more closely at your choice of IC: the vendor-as-partner model can do more to realize your idea than any venture capitalist or angel investor ever could--without eating into your long-term profits.
From 2009 to 2020: A history of developments in programmability
Signal Processing DesignLine Blog 8/28/2009 3 comments
Predictions come easy, but from the demise of FPGAs to the emergence of 32-core processors, DSPs are showing some strong trends and I think it is possible to divine what will happen in the next few years as we move towards the next order of magnitude increase in computational efficiency.
Old and new: Marconi's Irish roots
Signal Processing DesignLine Blog 8/17/2009 Post a comment
In a remote region of Ireland last week I happened upon a monument to Guglielmo Marconi's first commercial wireless transmission: between Rathlin Island and Ballycastle in North Antrim on July 6th. 1898.
How a felt-tipped pen saved the Apollo 11 mission
Signal Processing DesignLine Blog 7/20/2009 4 comments
Buzz Aldrin wasn't the first to "McGuyver" a solution to a difficult problem, but his use of a felt-tip pen to activate a broken circuit breaker to enable the Eagle to blast off from the moon surely ranks as one of the most dramatic.
Hey Red, is space exploration worth it?
Signal Processing DesignLine Blog 6/25/2009 8 comments
Hearing Buzz Aldrin talk at a book signing last night did little to relieve the nagging concern that there may be better ways to invest in our future than space exploration.
ADI launches online processor community help site

Analog Devices' digital signal processing group has jumped into the vendor-driven engineering community fray with an online community center where designers can get answers to their technical questions either from ADI specialists or their peers.
Can Star Trek really be revisited?
Signal Processing DesignLine Blog 5/8/2009 1 comment
This weekend we go back to the future with the launch of a reinvigorated Star Trek. By all accounts it has most of not all of the elements of the original, amplified by special effects. But can we really go back?
Which DSP for audio?
Signal Processing DesignLine Blog 5/1/2009 2 comments
For high-end audio it's typically been a choice between Freescale's Symphony, Cirrus Logic's lineup, TI's C6000 or ADI's TigerSharc, but with the OMAP and Blackfin processors getting faster, might they also now be encroaching upon that space and becoming viable options?
OMAP or Blackfin: Which do you prefer?

For years the two excellent architectures from two great companies have vied for your attention. You've looked at them, evaluated them, used them and even (though rarely) crossed back and forth between them. What's your verdict?
Engineers are political lightweights
Signal Processing DesignLine Blog 4/15/2009 Post a comment
The general response to any political commentary in a technical outlet is that politics should be kept out of engineering. As one reader put it, engineering is his 'refuge' from the political fray. Amen to that! But not so fast... We're shooting ourselves in the foot!
Bluetooth: Dead and alive

After all the research, development, marketing and debates, Bluetooth was successful. But only as a mobile headset cable replacement. So, is that it?
IMEC needs your help

IMEC, the famed Belgian research group is working on new, more-efficient approaches to dynamic, heterogeneous processing across distributed systems and is actively soliciting any and all suggestions as to how it should be done.
From math to reality: the story of memristors
Signal Processing DesignLine Blog 4/3/2009 Post a comment
Being able to see and resolve the nature of things through a kaleidoscope of mathematical equations is a gift that few of us have. Sure, most engineers have a 'knack' for math. Many of us even enjoy it and spend many hours noodling over arcane matrices, integrals and differentials. But how many truly view the world as a set of math equations?
Networking the lightbulb

What do you get when you combine a lightbulb, a sensor, and a network connection? That question sounds like the setup for a bad joke, but it is actually the secret to solving our energy problems.
The Tao of DSP

DSP and martial arts have a lot in common. It doesn't matter what tool, hardware or environment you use, having a vision and an understanding of the underlying mechanics needed to get you there is all that matters.
