McGinn had the semiconductor group dump commodity chips in favor of digital signal processors.

FORBES: Wired and restless

It makes digital signal processors, analog and mixed-signal circuits and algorithms for voice isolation and noise suppression.

WSJ: WageWorks, Audience Rise in Debuts

Texas Instruments credits him with helping that smorgasbord chipmaker further refine its focus on digital signal processors in 1997.

FORBES: The Art Of War

Embedded Processing products, which were responsible for 14% of 2009 revenues, consist of digital signal processors (DSPs) and microcontrollers.

FORBES: Buying Tech: Texas Instruments

Texas Instruments credits the strategist with helping the smorgasbord chipmaker further refine its focus on digital signal processors in 1997.

These short-term assignments must get done fast--designing filter algorithms for digital signal processors, say, or writing software for Internet-based phone calls.

FORBES: Hello brain. Good-bye rules.

The idea here is that IDT's switches will offload tasks that take up a lot of bandwidth from the digital signal processors, thus improving bandwidth performance by up to 20%.

FORBES: The Chips Are Down--Time To Buy

ViaVideo's engineers used two Philips TM-1000 digital signal processors capable of handling, between them, 6 billion operations a second -- the equivalent of seven Intel Pentium II microprocessors found in top-of-the-line PCs.

FORBES: Up & Comers: Told ya so

Traditional RISC processors can handle digital signal processing tasks, but the additional work sucks up valuable processing power that could be used elsewhere, said David Pelavin, product marketing manager for Hitachi's SuperH product family.
