Digital Signal Processor - Seminar

Processors certainly will be the workhorses associated with just about any computing technique. It is also acknowledged of which possibly prior to the DSP Processors has been designed there were some other overal l-purpose processors and that were being discovered wanting inside their functionality as soon as utilized in DSP programs. A digital signal processor (DSP) is a specialized microprocessor designed specifically for digital signal processing, generally in real -time computing.

This paper explains the importance of DSP, its preference over other processors, applications and its future scope in this technical world.

A digital signal processor (DSP) is a specialized microprocessor designed specifically for digital signal processing, generally in real -time computing.Any of the general-purpose processors are incapable of per forming such calculations in the short time span as needed by the DSP applications.

Digital signal processor has many benefits than analog sign control. This most crucial can be that DSP methods have the ability to accomplish duties cheaply that could be very hard or even difficult to realize utilizing analog technology. Examples of such applications are:

1. Speech Synthesis
2. Speech Recognition
3. Image Processing
4. DSP systems are insensitive to environment. They are insensitive to component tolerances. They have predictable and repeatable behavior. DSP systems are reprogrammable.

DSP systems are characterized by the algorithms us ed. Algorithm specifies the arithmetic operations to be performed but does not specify how that arithmetic is implemented. The selection of implementation technology is determined by the required speed and arithmetic precision. A key characteristic of a DSP system is its sample rate, the rate at which samples are consumed, processed and produced combined with the complexity of the algorithm, and sample rate determines the required speed of the implementation technology.
