Inverse lithography technology (ILT) is one of the promising resolution enhancement techniques (RET), as the advanced integrated circuits (IC) technology nodes still use the 193nm light source. Among all the algorithms for ILT, the level-set-based ILT (LSB-ILT) is a feasible choice with good production result in practice. However, existing ILT algorithms optimize mask at nominal process condition...
As a latest member in distributed computing technology family, the grid computing can play an increasingly important role with the progress of the DDM(Distributed Data Mining) technology in recent years. However, conventional data mining is not satisfied with the requirement due to the heterogeneous and distributed of the dataseis. Grid computing emerged as an important new field of distributed computing,...
Phase retrieval problem has attracted many interests for its wide application in many domains. In this paper we focus on the topic of retrieving the full complex wave field of the object plane from three or more diffraction planes. The iterative Fresnel algorithm always suffers from slow convergence and stagnation problems, while the generalized hybrid-input-output (GHIO) algorithm can effectively...
First, this paper introduces relation regulation in data mining, then an efficient algorithm SLIG (single-level large itemsets generation) based on relation theory and "AND" operation on recognizable vectors was proposed. SLIG transforms the production process of frequent itemset to the vector calculation process with relationship matrix but only needs to scan the database once. We optimize...
Wormhole switching with fixed priority preemption has been proposed as a possible solution for real-time on-chip communication. However, none of current priority assignment policies works well in on-chip networks due to some inherent properties of the protocol. In this paper, a novel heuristic branch and bound search algorithm is introduced to explore the possible priority ordering. Differing from...
