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. 606 $aField programmable gate arrays 606 $aIntegrated circuits$xDesign and construction 615 0$aField programmable gate arrays. 615 0$aIntegrated circuits$xDesign and construction. 676 $a621.395 700 $aUllah$b Salim$01337460 702 $aKumar$b Akash 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910674353203321 996 $aApproximate Arithmetic Circuit Architectures for FPGA-Based Systems$93056947 997 $aUNINA
