Sigmoid函数及其导函数的FPGA实现
Implementation of Sigmoid Function and Its Derivative on FPGA
摘要
Abstract
It has, based on ananlysis of Sigmoid function and constructing a look-up table whose variables are in [0,4], function value in [0. 5,1.0] ,implemented the Sigmoid function and its derivative by connecting with the arithmetic module. Experimently, this method can effectively save resources when ensuring rapid computing.关键词
