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, d...
