In the twenty-first century context, digital signal processing (DSP) is one of the most
promising and powerful emerging technologies, which has caused revolutionary changes in
a huge variety of applications. These include information technology, communications,
consumer electronics, audio/video and speech processing, medicine, geophysics and
security. In an increasingly demanding market, designers must apply innovative methods
and architectures to meet the stringent system requirements and performance constraints.
The development of complex signal processing systems is a multidisciplinary task that
involves the design of architectures that must be matched to the algorithms intended to be
executed on the particular system. Since recent (and foreseen) DSP algorithms have become
more complex, their implementation into hardware solutions has ramifications in all areas
of design, including architecture, software, circuits, and even modification of the original
algorithm. The increasing tendency towards high performance and low power systems has
required researchers to come up with innovative design methodologies and architectures
that can achieve these goals. In order to develop efficient and cost-effective DSP systems,
experts in each of these areas are continuously in demand for the intended application
domains.
Motivated by this flurry of activity in the subject of DSP in both the industrial and academic
contexts, this book presents some of the recent advances in basic implementations of DSP
tasks covering hardware/software solutions for application-specific circuits and
programmable DSP devices. Areas covered here include: architectures for basic operations
and elementary functions, parallel processing and pipelining, application-specific array
processors and programmable digital signal processors. This book is of particular interest to
electronic engineering and computer science students and researchers; this will benefit
practitioners in digital signal processor circuit design. |
