Computer architectures for digital signal processing

Includes bibliographical references (pages 102-105)The field of Digital Signal Processing (DSP) has expanded rapidly in\ud recent years as Very Large Scale Integrated (VLSI) circuits now\ud permit a wide range of DSP algorithms to operate in realtime or near\ud realtime. Digital signal processing is explored from a historical\ud perspective and a computational perspective in Chapter One. This\ud chapter describes the evolution of DSP from the pre World War II\ud era up to today's advanced signal processing. Chapter Two\ud characterizes the tasks to be performed in DSP. Particular attention is\ud paid to the . computational requirements, fundamental computational\ud primitives, and the inherent levels of parallelism within these\ud algorithms. Chapter Three examines the breakthrough which\ud occurred when general purpose Von Neuman based microprocessors\ud were transformed into general purpose digital signal processors. The\ud fundamental principles of systolic and wavefront array processor\ud architectures are explored in Chapter Four. Examples are given of\ud actual array implementations and the application software required\ud to tie system components together. Of all the factors that influence\ud computer architectures for DSP, technology is without question the \ud most important. Chapter Five describes todays processing\ud technologies and the directions toward which this field is heading.\ud Design complexity has become a dominant cost limit in the\ud development of VLSI DSP systems. Without new design tools, the\ud advances in algorithms, architectures, and I.C. fabrication\ud technologies discussed in the previous chapters could not be fully\ud utilized. Chapter Six explores the computer aided design tools\ud required to reduce design cycles and costs and to increase the\ud probability of first-pass success in these new DSP systems. Finally,\ud appendices A, B, and C highlight common problems which system\ud designers must face when applying todays new architectures and\ud technologies
