Introduction to digital signal processing

Although most of this book is concerned with the development of digital control techniques, we are broadly looking at a topic which is now called digital signal processing. The PC processor has developed into a powerful processor, but it is still out-performed by dedicated digital signal processors (DSP). The essential difference between a DSP and a microprocessor is that a DSP processor has features designed to support high-performance, repetitive, numerically intensive tasks. In contrast, general-purpose processors or microcontrollers are neither specialized for a specific kind of application (in the case of general-purpose processors), nor are they designed for control-oriented applications (in ...
