The framework of digital signal processing is explained in this book with the help of descriptive information. Digital signal processing (DSP) comprises of a broad variety of functions in which the execution of high-performance systems to meet severe requirements and performance constraints is fast becoming a topic of interest, both in the practical and educational contexts. Assumed to be accessible to a significant number of people, the aim of this book is to provide students, researchers, engineers and the industrial society with a reference to the most recent developments in rising issues in the design and execution of DSP systems for purpose-oriented circuits and programmable tools. The book deals with various topics including real-time audio functions, optical signal processing, image and video processing and superior architectures and executions. It will allow students and experts to deal with the significant gap in information in the changeover from algorithm requirement to the design of architectures for VLSI achievements.
