Outline of Final Research Achievements

We proposed the Multi-terminal multiple-valued decision diagram for characteristic function representing cluster decomposition (MTMDD for CF) as a new kind of a decision diagram, then presented at the international conferences. Also, we applied the edge-valued MDD(k), which is a variation of the MTMDD for CF, to realize a new embedded processor. We used it to the multi-core processor to realize the packet classification. Also, we developed the commercial packet classifier with co-development company.
