A special-purpose compiler for look-up table and code generation for function evaluation

Abstract—Elementary functions are extensively used in com-puter graphics, signal and image processing, and communication systems. This paper presents a special-purpose compiler that automatically generates customized look-up tables and imple-mentations for elementary functions under user given constraints. The generated implementations include a C/C++ code that can be used directly by applications running on multicores, as well as a MATLAB-like code that can be translated directly to a hardware module on FPGA platforms. The experimental results show that our solutions for function evaluation bring significant performance improvements to applications on multicores as well as significant resource savings to designs on FPGAs.
