In the piecewise function evaluation a non-uniform segmentation method for arithmetic function is evaluated based on polynomial approximations. Function evaluator is very much dominant task in the field of VLSI. Entire system speed or performance depends on how fast functions are calculated and solved. Few papers already have been done based on uniform segmentation and non-remapping of ROMs. In the author paper, trigonometric and logarithmic functions are considered. To evaluate functions ROM plays a major role in terms of accessing.
