The error resiliency of applications such as media processing has provided designers with a new technique called approximate computing (AC), which abandons exactness of computation in favor of improved efficiency. In functional approximation, which is our focus here, a more simpler function different than the actual design is implemented that can be generated manually by the designer (in the case of approximate arithmetic blocks) or automatically (when an arbitrary function is given). We generated an approximate non-iterative divider which is highly accurate and energy efficient.Related work:
