Abstract During the past decade digital signal processors (DSPs) have hit critical mass for high-volume applications. Today, the entire digital wireless industry operates with DSP-enabled handsets and base stations. This paper gives a plain introduction to DSP devices. The discussion focuses on the digital electronics aspects of DSP as well as applications of DSPs. DSP architecture, characteristics are explained in the discussion followed by a major application of DSPs in the field of Telecommunications.
Keywords: DSP, Signal Processing, Digital Electronics, Microprocessors, Embedded Systems
Introduction
Digital signal processing is one of the core technologies, in rapidly growing application areas, such as wireless communications, audio and video processing and industrial control. The number and variety of products that include some form of digital signal processing has grown dramatically over the last few years. DSP has become a key component, in many of the consumer, communications, medical and industrial products which implement the signal processing using microprocessors, Field Programmable Gate Arrays (FPGAs), Custom ICs etc. Due to increasing popularity of the above mentioned applications, the variety of the DSP-capable processors has expanded greatly. DSPs are processors or microcomputers whose hardware, software, and instruction sets are optimized for high-speed numeric processing applications, an essential for processing digital data, representing analog signals in real time. The DSP processors have gained increased popularity because of the various advantages like reprogram ability in the field, cost-effectiveness, speed, energy efficiency etc.
