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.
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.
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.
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.
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!
