VLSI for signal processing: Signal processing chips and applications

Recent advances in very large scale integration (VLSI) have contributed to the current digital signal processors. These processors are just special-purpose fast microprocessors characterized by architectures and instructions suitable for real-time digital signal processing (DSP) applications. The commercial DSP processor, a little more than a decade old, has emerged because of the ever-increasing number of signal processing applications. DSP processors are now being utilized in a number of applications from communications and controls to speech and image processing. They have found their way into talking toys and music synthesizers. A number of texts (such as Chassaing, 1992) and articles (such as Ahmed and Kline, 1991) have been written, discussing the applications that use DSP processors and the recent advances in DSP systems
