Abstract
Systems and methods for performing hardware approximation of functions are provided. In one example, a system comprises a controller, a plurality of multiplexors, configurable arithmetic circuits, and a mapping table that stores a set of function parameters. According to a mode of operations, the controller may configure the plurality of multiplexors to forward the set of function parameters or a subset of the function parameters to the arithmetic circuits to compute an approximation result. In a case where the subset of the function parameters is forwarded to the arithmetic circuits, the controller may configure the arithmetic circuits to perform post-processing, such as quantization, of the approximation result.
