Advances in signal and image processing together with increasing computing power
are bringing mobile technology closer to applications in a variety of domains like
automotive, health, telecommunication, multimedia, entertainment and many others.
The development of these leading applications, involving a large diversity of
algorithms (e.g. signal, image, video, 3D, communication, cryptography) is classically
divided into three consecutive steps: a theoretical study of the algorithms, a
study of the target architecture, and finally the implementation. Such a linear design
flow is reaching its limits due to intense pressure on design cycle and strict performance
constraints. The approach, called Algorithm-Architecture Matching, aims to
leverage design flows with a simultaneous study of both algorithmic and architectural
issues, taking into account multiple design constraints, as well as algorithm and
architecture optimizations, that couldn’t be achieved otherwise if considered separately.
Introducing new design methodologies is mandatory when facing the new
emerging applications as for example advanced mobile communication or graphics
using sub-micron manufacturing technologies or 3D-Integrated Circuits. This diversity
forms a driving force for the future evolutions of embedded system designs
methodologies.
The main expectations from system designers’ point of view are related to methods,
tools and architectures supporting application complexity and design cycle reduction.
Advanced optimizations are essential to meet design constraints and to enable
a wide acceptance of these new technologies.
This book presents a collection of selected contributions addressing different aspects
of Algorithm-Architecture Matching approach ranging from sensors to architectures
design. The scope of this book reflects the diversity of potential algorithms,
including signal, communication, image, video, 3D-Graphics implemented
onto various architectures from FPGA to multiprocessor systems. Several synthesis
and resource management techniques leveraging design optimizations are also
described and applied to numerous algorithms.
