Of Processors and Processing

ABSTRACT

Digital signal processing is a stealth technology. It is the core enabling technology in everything from your cellphone to the Mars Rover. It goes much further than just enabling a one-time breakthrough product. It provides ever-increasing capability; compare the performance gains made by dial-up modems with the recent performance gains of DSL and cable modems. Remarkably, digital signal processing has become ubiquitous with little fanfare, and most of its users are not even aware of what it is. Therefore, it is worthwhile to look at the development history of DSP, an explanation of what the technology is, and a review of the many technologies that are used to implement modern digital signal processing systems.
