Research Abstract

In this research, we devised a piecewise polynomial approximation method based on a new spatial segmentation algorithm in order to develop an efficient synthesis system for multivariable numeric function generators. By using the synthesis system based on the new approximation method, even non-experts can easily design fast and compact numeric function generators. It can significantly improve the design productivity of digital circuits that would degrade due to lack of designers. And, our programmable architecture can be expected to reduce design and development costs of digital systems. This is because various numeric functions can be realized with a single circuit, and it can be reused for many kinds of digital systems.
