But we have taken the advantages at the cost of performance due to lack of an available expression space for a long immediate value, a three-address mode and so on. This paper presents a new instruction coalescing technique named as move folding to remove redundant move instructions caused by the limitation of the 16-bit instruction set.We prove effectiveness of the technique by implementing it on a commercial microprocessor. The proposed move folding technique improves speedup of 5% on average and up to 18% at the cost of 4.3% hardware complexity increment.","PeriodicalId":155998,"journal":{"name":"2008 IEEE 8th International Conference on Computer and Information Technology Workshops","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128326948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conventional anisotropic diffusion is performed in four directions without condition in the previous method. In this paper, a new anisotropic diffusion transform based on directions of edges is proposed. The proposed diffusion is not performed at a pixel which is not an edge. The range of proposed diffusion is selected adaptively according to the number of the directions of edges. Experiments results show that the process time of the proposed method over conventional methods, can be faster slightly. Also, the proposed method can improve the image quality of diagonal edges in ultrasound image with speckle noise.","PeriodicalId":155998,"journal":{"name":"2008 IEEE 8th International Conference on Computer and Information Technology Workshops","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134039056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are many possible ways in which parameters of regression models are assumed to change. With better understanding of how parameters change, estimation and testing procedures for various structural changes can be developed. This paper uses an exploratory way by augmenting the multivariate regression framework with data mining to study the less understood structural change concept by examining the effects of IT investments on industry profiles.
