3.8.1 Basic Features of the DSP

In this section are discussed the major hardware components which allow a very efficient implementation of digital signal processing algorithms. These elements are not usually found in universal microprocessors and must be replaced by additional software.

3.8.1.1 Multiplication and Accumulation

In respect, A/D converter for a fixed-point DSP the number of bits determines the dynamic range of signal processing. Figure 3.67 shows the dynamic range of a typical fixed-point DSP. The main task for DSP hardware is described by equation
