Texas Instruments is the top-shelf supplier of digital-signal processors for the wireless basestations that carriers use to communicate with cell phones, but now Freescale is challenging with unique architectural features in its new basestation DSPs. Look for Freescale and TI to wage a specs-man-ship rivalry well into the coming decade. R. Colin Johnson, Kyoto Prize Fellow @NextGenLog
Freescale's new basestation DSP aims to ease transition from 3G to 4G with application-specific hardware units.
Here is what my story in EETimes says about DSPs for basestations: Freescale Semiconductor Inc. appeared to one-up Texas Instruments Inc. Wednesday (Nov. 17) by rolling out a digital signal processor (DSP) core that achieved a higher rating from benchmarking consulting firm BDTI Inc. Last week, TI reported that its C66x DSP core achieved a BDTImark2000 score of 16,690. Freescale countered Wednesday that its new redesigned SC3850 core achieves a BDTIsimMark2000 score of 18,500. As network operators convert from 3G to 4G, the system-on-chip (SoC) DSPs that execute the increasingly complex air-interface protocols—from LTE to WiMAX to WCDMA and HSPA+—are waging a benchmark war...

Cognitive computers—cognizers—aim to instill human-like intelligence into our smartphones, tablets and other electronic devices using microchips that emulate the human brain. Dubbed the “Future of Computing” by the NYTimes, one of the “Best Innovation Moments of 2011” by the Washington Post and one of “10 World Changing Ideas” in a Scientific American cover story “A Computer Chip that Thinks” this book reveals how neuroscience and computer science are merging in a new era of intelligent machines light-years beyond Apple's Siri, IBM's Watson.
Next-generation electronics and technology news stories published non-stop for 20+ years, R. Colin Johnson's unique perspective has prompted coverage of his articles in a diverse range of major media outlets--from the ultra-liberal National Public Radio (NPR) to the ultra-conservative Rush Limbaugh Show.
