| Outline of Final Research Achievements |
In this study, we developed a programmable multi-dimensional digital signal synthesizer (DSS) and its computer aided design tool. At the beginning of the study, we was going to realize a multi-dimensional DSS directly with a single framework of circuit. But, we could not find a ways to sufficiently reduce circuit complexity increased by increase of dimension, and thus, we had no other choice than to realize a multi-dimension DSS with a combination of one-dimensional DSSs, similarly to conventional methods. However, unlike conventional methods, we newly designed an arithmetic transform based one-dimensional DSS intended to make it multi-dimension. Thus, the developed method allows us to design multi-dimensional DSSs more easily than conventional methods. We applied the developed method to design of a virtual sensor used in engine control units for cars, and succeeded in automatic design of the virtual sensor generating signals about 55 times faster than its software implementation.
