Digital signal processing (DSP) is used in a wide range of applications such as speech, telephone, mobile radio, satellite communications, biomedical, image, video, radar and sonar. Different applications of signal processing impose different constraints on hardware architectures. This book is concerned with design of real-time architectures where signal samples are processed as soon as these are received from the signal source. This is in contrast with batch-mode processing where signal samples are first stored in buffers and then processed in batch. Real-time DSP architectures are designed to match the hardware speed to the application sample speed. Since different real-time applications require different sample rates, a DSP algorithm needs to be implemented in different styles for various applications. Thus, design of real-time architectures for these applications requires study of families of architectures.
