Accuracy enhancement of equal segment based approximate adders.
IET Computers & Digital Techniques(2018)
摘要
Recently, several approximate adders have been proposed based on the design concept of Equal Segment Adder (ESA), i.e. to segment an N-bit adder into several smaller and independent equal size sub-adders. In this study, the authors propose analytical models to estimate Pass Rate (PR), delay, power and area of ESAs, where PR represents the probability of output to be correct. From the proposed anal...
