Due to such non-uniform accesses some sets of large sized caches are used heavily while some other sets are used lightly. This paper presents a technique WS-DAM, to dynamically increase the associativity of the heavily used sets without increasing the cache size. The heavily used sets can use the idle ways of the lightly used sets to distribute the load. A limited number of ways from every lightly used set are reserved for the heavily used sets. To search a block in a heavily used set, both: the set and the entire reserve area is searched. To reduce the cost of searching the entire reserve storage an additional tag-array is used. During execution the sets are re-categorized at intervals. The proposed technique needs much lesser storage, area and power overhead as compared to the other similar techniques. It improves both miss rate and CPI by 14.46% and 6.63% respectively as compared to an existing technique called V-Way. WS-DAM is also compared with another existing proposal called CMP-VR and it improves the performance by 9% and 4.20% in terms of miss-rate and CPI respectively.","PeriodicalId":206481,"journal":{"name":"Proceedings of the 30th Annual ACM Symposium on Applied Computing","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122595541","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}

Both AI and control based robotics are active and successful research areas, but research is often conducted by well separated communities. In this paper, we compare the two approaches in a case study for the design of a robot that should move its arm towards an object with the help of camera data. The control based approach is a model-free version of Image Based Visual Servoing (IBVS), which is based on mathematical modeling of the sensing and motion task. The AI approach, here denoted Behavior-Based Visual Servoing (BBVS), contains elements that are biologically plausible and inspired by schema-theory. We show how the two approaches lead to very similar solutions, even identical given a few simplifying assumptions. This similarity is shown both analytically and numerically. However, in a simple picking task with a 3 DoF robot arm, BBVS shows significantly higher performance than the IBVS approach, partly because it contains more manually tuned parameters. While the results obviously do not apply to all tasks and solutions, it illustrates both strengths and weaknesses with both approaches, and how they are tightly connected and share many similarities despite very different starting points and methodologies.","PeriodicalId":206481,"journal":{"name":"Proceedings of the 30th Annual ACM Symposium on Applied Computing","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129849857","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}

This replicated functionality, known as a code clone, has a diverse set of causes and can have moderate to severe adverse effects on a software project in a variety of ways. A code clone is defined as multiple code fragments that produce similar results when provided the same input. While there is an array of powerful clone detection tools, most suffer from a variety of drawbacks including, most importantly, the inability to accurately and reliably detect the more difficult clone types. This paper presents a new technique for detecting code clones based on concolic analysis, which uses a mixture of concrete and symbolic values to traverse a large and diverse portion of the source code. By performing concolic analysis on the targeted source code and then examining the holistic output for similarities, code clone candidates can be consistently identified. We found that concolic analysis was able to accurately and reliably discover all four types of code clones with an average precision of .8, recall of .91, F-score of .85 and an accuracy of .99.","PeriodicalId":206481,"journal":{"name":"Proceedings of the 30th Annual ACM Symposium on Applied Computing","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128473127","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}
