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

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

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

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.

How a felt-tipped pen saved the Apollo 11 mission

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.

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?

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!

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?
