This book presents various novel architectures for FPGA-optimized accurate and approximate operators, their detailed accuracy and performance analysis, various techniques to model the behavior of approximate operators, and thorough application-level analysis to evaluate the impact of approximations on the final output quality and performance metrics. As multiplication is one of the most commonly used and computationally expensive operations in various error-resilient applications such as digital signal and image processing and machine learning algorithms, this book particularly focuses on this operation. The book starts by elaborating on the various sources of error resilience and opportunities available for approximations on various layers of the computation stack. It then provides a detailed description of the state-of-the-art approximate computing-related works and highlights their limitations.

Computer arithmetic has become so fundamentally embedded into digital design that many engineers are unaware of the many research advances in the area. As a result, they are losing out on emerging opportunities to optimize its use in targeted applications and technologies. In many cases, easily available standard arithmetic hardware might not necessarily be the most efficient implementation strategy. Multiple-Base Number System: Theory and Applications stands apart from the usual books on computer arithmetic with its concentration on the uses and the mathematical operations associated with the recently introduced multiple-base number system (MBNS). The book identifies and explores several diverse and never-before-considered MBNS applications (and their implementation issues) to enhance computation efficiency, specifically in digital signal processing (DSP) and public key cryptography. Despite the recent development and increasing popularity of MBNS as a specialized tool for high-performance calculations in electronic hardware and other fields, no single text has compiled all the crucial, cutting-edge information engineers need to optimize its use. The authors’ main goal was to disseminate the results of extensive design research—including much of their own—to help the widest possible audience of engineers, computer scientists, and mathematicians. Dedicated to helping readers apply discoveries in advanced integrated circuit technologies, this single reference is packed with a wealth of vital content previously scattered throughout limited-circulation technical and mathematical journals and papers—resources generally accessible only to researchers and designers working in highly specialized fields. Leveling the informational playing field, this resource guides readers through an in-depth analysis of theory, architectural techniques, and the latest research on the subject, subsequently laying the groundwork users require to begin applying MBNS.

A new design method of compact residue arithmetic circuit using multiple-valued charge-coupled devices (CCD's) is proposed. The multiple-valued ring counter for the residue arithmetic is designed by using the CCD's. Because the structure of the counter is very simple, it is effectively used as the basic component to construct the residue arithmetic circuit. The modulo-m addition is performed by shifting the modulo-m multiple-valued ring counter, and the coefficient multiplication is done by converting the multiple-valued code between the counters. The most important advantages of the proposed adder and multiplier are the compact hardware and the uniform operating time, so that these arithmetic circuits can be effectively employed for the pipelining digital signal processing system. Finally, it is demonstrated that the hardware complexity of the digital filter constructed with the quaternary logic CCD's can be reduced to 70% compared with the corresponding binary implementation.

This textbook provides comprehensive coverage for courses in the basics of design and implementation of digital filters. The book assumes only basic knowledge in digital signal processing and covers state-of-the-art methods for digital filter design and provides a simple route for the readers to design their own filters. The advanced mathematics that is required for the filter design is minimized by providing an extensive MATLAB toolbox with over 300 files. The book presents over 200 design examples with MATLAB code and over 300 problems to be solved by the reader. The students can design and modify the code for their use. The book and the design examples cover almost all known design methods of frequency-selective digital filters as well as some of the authors’ own, unique techniques.

Approximate adders have been considered as a potential alternative for error-tolerant applications to trade off some accuracy for gains in other circuit-based metrics, such as power, area and delay. 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. This multiplier leverages a newly designed approximate adder that limits its carry propagation to the nearest neighbors for fast partial product accumulation. Different levels of accuracy can be achieved through a configurable error recovery by using different error reduction strategies. These designs use OR gates and the proposed approximate adder for two configurations of the multiplier: approximate multiplier 1 (AM1) and approximate multiplier 2 (AM2). Both AM1 and AM2 have a low mean error distance, i.e., most of the errors are not significant in magnitude. Compared to the Wallace multiplier, a 16 * 16 bit AM1 implemented in a 28-nm CMOS process shows a reduction in delay and power of 20% and up to 69%, respectively. AM2 has a better accuracy compared to AM1 but with a longer delay and higher power. Image processing applications such as image sharpening and smoothing are used to show the quality of the approximate multipliers in error-tolerant applications. It is shown that by utilizing an appropriate error recovery, the proposed approximate multipliers achieve similar processing accuracy as traditional accurate multipliers, but with significant improvements in power and performance. A comparative evaluation of existing approximate multipliers, including the proposed ones, is also presented in this thesis. Monte Carlo simulations are performed to evaluate the error characteristics of these multipliers. Circuit simulations are further run to compare the delay, area and power consumption of these multipliers. The proposed approximate multipliers have high accuracies and lowest power-delay-products among all the designs, while the other designs have at least one major shortcoming in terms of error and/or circuit characteristics. Therefore the proposed designs achieve the best tradeoff between accuracy, delay and power.

This book presents a complete and accurate study of algebraic circuits, digital circuits whose performance can be associated with any algebraic structure. The authors distinguish between basic algebraic circuits, such as Linear Feedback Shift Registers (LFSRs) and cellular automata and algebraic circuits, such as finite fields or Galois fields. The book includes a comprehensive review of representation systems, of arithmetic circuits implementing basic and more complex operations and of the residue number systems (RNS). It presents a study of basic algebraic circuits such as LFSRs and cellular automata as well as a study of circuits related to Galois fields, including two real cryptographic applications of Galois fields.
