Digital signal processing is to perform signal processing using digital techniques with the aid of digital hardware and/or some kind of computing device. (Signal processing can, of course, be analog as well.) A specially designed digital computer or processor dedicated to signal processing applications is called a digital signal processor.

In this chapter, we will focus on hardware issues associated with digital signal processor chips, and we will compare the characteristics of a DSP to a conventional, general-purpose microprocessor. (The reader is assumed to be familiar with the structure and operation ...
