The volume presents 46 full revised papers carefully selected by the program committee from a large number and wide range of submissions. The papers document the progress achieved since the predecessor conference (see LNCS 849).

They are organized in sections on architectures, platforms, tools, arithmetic and signal processing, embedded systems and other applications, and reconfigurable design and models.

Unlike other publications that limit discussion toarithmetic units for general-purpose computers, this text featuresa practical focus on embedded systems. Following an introductory chapter, the publication is divided intotwo parts. The first part, Mathematical Aspects and Algorithms,includes mathematical background, number representation, additionand subtraction, multiplication, division, other arithmeticoperations, and operations in finite fields. The second part,Synthesis of Arithmetic Circuits, includes hardware platforms,general principles of synthesis, adders and subtractors,multipliers, dividers, and other arithmetic primitives.

Existing approximate adder designs have shown substantial advantages in improving many of these operational features. However, the error characteristics of the approximate adders still remain an issue that is not very well understood. A simulation-based method requires both programming effort and time-consuming simulations for evaluating the effect of errors. This method becomes particularly expensive when dealing with various sizes and types of approximate adders. As the first contribution of this thesis, a framework based on analytical models is proposed for evaluating the error characteristics of approximate adders. Error features such as the error rate and the mean error distance are obtained using this framework without developing functional models of the approximate adders for time-consuming simulation.

As an example, the estimate of peak signal-to- noise ratios (PSNRs) in image processing is considered to show the potential application of the proposed analysis. This analytical framework provides an efficient method to evaluate various designs of approximate adders for meeting different figures of merit in error-tolerant applications. In addition to adders, multipliers are also key arithmetic circuits in many error-tolerant applications such as digital signal processing (DSP). As the second contribution of this dissertation, a novel approximate multiplier with a lower power consumption and a shorter critical path than traditional (accurate) multipliers is proposed for high-performance DSP applications.
