| Outline of Final Research Achievements |
The research on high level synthesis of system LSI were conducted. First, in the scheduling problem, a method based on a combination of mathematical programming and graph theory was proposed for the dynamic power optimization problem. For leakage power optimization problem, a method with the modifications of the above method and additional post-processing were proposed. In both problems, optimal solutions were obtained in most cases. In the port assignment problem, a method to avoid local optimal solutions considering sub-solution space and a method to reduce processing time were proposed. Optimal solutions were obtained for all the evaluation data. In the TSV assignment problem for three-dimensional LSI, a method to reduce the scale of the problem without sacrificing the solution quality was proposed based on a hierarchical design method. The CPU time was reduced to about 1/38 of the conventional methods.
