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.

This book describes the optimized implementations of several arithmetic datapath, controlpath and pseudorandom sequence generator circuits for realization of high performance arithmetic circuits targeted towards a specific family of the high-end Field Programmable Gate Arrays (FPGAs). It explores regular, modular, cascadable and bit-sliced architectures of these circuits, by directly instantiating the target FPGA-specific primitives in the HDL. Every proposed architecture is justified with detailed mathematical analyses. Simultaneously, constrained placement of the circuit building blocks is performed, by placing the logically related hardware primitives in close proximity to one another by supplying relevant placement constraints in the Xilinx proprietary “User Constraints File”. The book covers the implementation of a GUI-based CAD tool named FlexiCore integrated with the Xilinx Integrated Software Environment (ISE) for design automation of platform-specific high-performance arithmetic circuits from user-level specifications. This tool has been used to implement the proposed circuits, as well as hardware implementations of integer arithmetic algorithms where several of the proposed circuits are used as building blocks. Implementation results demonstrate higher performance and superior operand-width scalability for the proposed circuits, with respect to implementations derived through other existing approaches. This book will prove useful to researchers, students and professionals engaged in the domain of FPGA circuit optimization and implementation.

Field Programmable Gate Array technology has grown to a stage where entire digital systems with their I/O interfaces can be implemented in single FPGAs. Even so, FPGAs are primarily digital devices with little inbuilt facilities for direct interaction with the analog world. The Multi-Technology FPGA goes beyond this limitation by integrating multi-technology and analog blocks with the regular FPGA fabric. To implement circuits on the MT-FPGA, an automatic configuration bit stream generation system is needed. Designing and implementing such a system has been the point of investigation for this thesis. The major goal in this exercise is to make the system as generic and architecture independent as possible, so as to retarget it to different architectures. The system takes as its input, the output files from FPGA synthesis tools and an architecture specification of the fabric. An XML based architecture specification format and an object-oriented software tool code named "XBits"has been developed. The first part of the thesis explains the specifics of the format and the internals of XBits. Results on academic benchmarks implemented using XBits are also given. As a second part of the thesis, the present MT-FPGA architecture is analyzed for its suitability for large arithmetic circuit implementations. Since the MT-FPGA presents a parallel platform for mapping circuits; signal processing applications that benefit greatly from multiple implementations of functions acting in parallel on long input data streams are of special interest to the MT-FPGA. A new architecture is proposed as a result of this study, which enhances the logic utilization of the FPGA fabric and the speed of arithmetic operations on the MT-FPGA. Associated analysis and comparison of this new architecture with the original architecture is also presented.

The book is composed of two parts. The first part introduces the concepts of the design of digital systems using contemporary field-programmable gate arrays (FPGAs). Various design techniques are discussed and illustrated by examples. The operation and effectiveness of these techniques is demonstrated through experiments that use relatively cheap prototyping boards that are widely available. The book begins with easily understandable introductory sections, continues with commonly used digital circuits, and then gradually extends to more advanced topics. The advanced topics include novel techniques where parallelism is applied extensively. These techniques involve not only core reconfigurable logical elements, but also use embedded blocks such as memories and digital signal processing slices and interactions with general-purpose and application-specific computing systems. Fully synthesizable specifications are provided in a hardware-description language (VHDL) and are ready to be tested and incorporated in engineering designs. A number of practical applications are discussed from areas such as data processing and vector-based computations (e.g. Hamming weight counters/comparators). The second part of the book covers the more theoretical aspects of finite state machine synthesis with the main objective of reducing basic FPGA resources, minimizing delays and achieving greater optimization of circuits and systems.
