LSI (large-scale integration) that plays a central role in information communication consumes large amounts of electricity. Reducing the energy consumption of LSI, and extending the operating time of devices with LSI or the lifespan of the device itself is becoming an urgent issue.


We are implementing a generalized rule that remains consistent throughout higher and lower processes by creating an abstraction model based on new concepts of “strong coupling” and “weak coupling” in regard to the three factors of functional modules, memory, and control that make up LSI.
We are also able to establish LSI design technology that achieves an “LSI synthesis algorithm that integrates high and low points of low energy” through mutual harmonization of the design process in accordance with the implemented rule, without adhering to traditional hierarchical design processes.


Not only will individual LSI parts become more energy efficient, but an LSI design with extremely high-precision energy optimization will be made possible through “virtual complete control” of higher to lower processes using the algorithms of this research. As a result of this, a maximum universal energy saving of over 50% will be made possible in all LSI that will be designed and manufactured in the future.


Traditional design technology allowed energy saving designs on a per process level, but the expected reductions could not be achieved over the entire LSI. By comparison, the implementation of abstraction models and algorithms in LSI designs will enable efficient designs through a more holistic approach.
