The language specification of fuzzy systems description language (FDL) was settled on as a common standard of the system development language to implement the fuzzy theory. It is possible to develop the system that uses FDL on general UNIX-OS now. However, the main applied field of the fuzzy theory is a built-in control field. In a word, it is necessary to use FDL only in the built-in control field. So that, the language specification and implementation of FDL were suitable for the built-in system development was considered. As a result, we can correspond by the improvement of the language implementation even if we do not change the language specification. Moreover, we considered the computational effort and the memory consumption as a development guideline for the built-in system written in FDL. A concrete consideration is a usage of fixed zero point that takes the place of floating point, and LUT. In this thesis, we report on these improvement point and guideline.
