Abstract

In a system that requires a fast response characteristic rather than an accurate response, the ability to respond quickly, even at the expense of accuracy, is beneficial to the system. In this paper, we propose the method that divides the data into several segments and estimates the linear equation of polynomial characteristic separately for each segment. As the smaller the size of segments, the reduced order of the polynomials to be estimated makes the smaller amount of calculation required. It minimizes the reduction in the accuracy of the estimated polynomial characteristic and completes the calculation faster than applying estimation to the entire data. The proposed method was implemented and evaluated on the target embedded board, and the result shows that the optimal segment size for the proposed polynomial approximation.
