Wanhammar L. DSP Integrated Circuits

Academic Press, 1999. — 561 p.The book DSP Integrated Circuits is used as a textbook for the course "Application-Specific Integrated Circuits for Digital Signal Processing" given at Linkoping University. This text is intended to fill a gap in the market for textbooks on design of digital signal processing systems using VLSI technologies. The intent is to present a comprehensive approach to system design and implementation of DSP systems using advanced VLSI technologies. We also try to present a coherent paradigm for the whole design process, i.e., a top-down design approach is stressed throughout the book. The emphasis is on DSP algorithms, scheduling, resource allocation assignment and circuit architectures. We derive an efficient implementation strategy that is based on asynchronous bit-serial processing elements that can be matched to the DSP algorithm and the application requirements. The aim is to minimize power consumption and chip area, but equally important is the use of a structured design methodology that allows an error-free design to be completed according to the project schedule. The presentation necessarily represents a personal view, since there is no unique global view to which everyone in the field agrees.
The textbook presents the design process in a top-down manner. Throughout the text, three case studies are presented. The three examples are selected in order to demonstrate different characteristics of common DSP applications. The first case study involves the design of an interpolator based on lattice wave digital filters. The major design problems are the complicated scheduling of the operations and the resource allocation. The second case study is the design of an FFT processor. The major problem here is the partitioning of the algorithm into appropriate processes that can be mapped onto the processing elements. The third case study is the design of a two-dimensional discrete cosine transform for high-definition TV (HDTV). The major problems here are the high I/O data rate and the high arithmetic work load.
The textbook is aimed for engineers and scientists involved in digital signal processing, real-time systems, including computer-aided design, application-specific integrated circuit design, and VLSI technology. The textbook provides the necessary background in DSP that is needed in order to appreciate the case studies. Of course, it is beneficial if the student has a prior basic understanding of digital signal processing techniques.
