Abstract :
This paper presents hardware implementations of Taylor series. The focus will be on the exponential function but the methodology is applicable on any unary function. Two different architectures are investigated, one, original, straight forward and one modified structure. The outcomes are higher performance, lower area, and lower power consumption for the modified architecture compared to the original.
