However, there is still a gap in the use of wireless communication systems. The current standard does not adopt wireless communication options which allow low maintenance and installation costs. This paper proposes a solution for the integration of wireless communication technologies within the standard IEC 61850 attending the requirements of the power substations, such as reliability and security even in real-time applications.","PeriodicalId":359419,"journal":{"name":"2013 III Brazilian Symposium on Computing Systems Engineering","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128389578","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}

In this scenario, which has been expanding with trends such Internet of Things (IoT) and Ubiquitous computing, becomes even more significant the process of debugging. The use of high-level language virtual machines (VM) on embedded systems can avoid issues on the portability, safety and memory management. However, it presents challenges for debugging due to lack of memory resources and VM's hardware abstractions. This paper presents an out-of-process Java Virtual Machine (JVM) debugger based on the Java Platform Debugger Architecture (JPDA). The proposed method reduces the complexity of debug implementation inside the VM itself without loosing the link between Java and native code. Thus, it allows the debugging using the high-level language instead of native compiled code.","PeriodicalId":359419,"journal":{"name":"2013 III Brazilian Symposium on Computing Systems Engineering","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126274015","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}

To speed up the development process and make it as more transparent as possible to the programmer, parallelism is exploited through the use of Application Programming Interfaces (API). Each one of these API implements different ways to exchange data. However, data exchange occurs between the threads in shared memory regions, which have higher energy consumption. Therefore, each API will present different energy costs to communicate. In this paper, we present the first step to show that different APIs have different impacts on energy consumption, through the analysis of the communication mechanism that each one employs, the number of memory accesses necessary for the communication, and the number of executed instructions according to the API used. Our results show that OpenMP presents a higher communication overhead, with more memory accesses and instructions executed, when compared to Pthreads.","PeriodicalId":359419,"journal":{"name":"2013 III Brazilian Symposium on Computing Systems Engineering","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123788170","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}
