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. Provides architectures of approximate arithmetic circuits optimized for FPGA-based systems; Describes a methodology for implementing application-specific approximate circuits; Introduces technique for concurrent utilization of approximation knobs.Field programmable gate arraysIntegrated circuitsDesign and constructionField programmable gate arrays.Integrated circuitsDesign and construction.621.395Ullah Salim1337460Kumar AkashMiAaPQMiAaPQMiAaPQBOOK9910674353203321Approximate Arithmetic Circuit Architectures for FPGA-Based Systems3056947UNINA
