The selection of compiler options is important as the resulted performance can vary significantly. The best combination of compiler options is not only dependent on the program itself, but it also is highly related to the configuration of the system and the architecture of the processor that the program runs on. The determination of the best combination of compiler options is very complicated, as its complexity grows exponentially with the number of the optimization options the compiler offers. Many previous work attempts to shorten the search time by reducing the complexity of the problem. However, most of them focus on computational intensive applications, which run with little or no invocation of kernel functions and device input/output activities, which often dominate system performance in specific embedded environment, such as network appliance. This paper aims at system-wide compiler optimizations selection for embedded applications. We proposed an automated framework to judiciously select the compiler options not only for the control software in the user space but also for the associated kernel functions which perform the I/O operations for an embedded application. For this framework, we implemented compiler optimization selection algorithms and evaluated its efficiencies with and without performance monitoring hardware support. We argue that our framework is a platform-independent and system-level compiler options selection framework. Our experience in optimizing the performance of the embedded application on a production storage appliance show that an I/O-intensive application composed by various kernel modules device drivers under Linux can be optimized effectively and systematically.","PeriodicalId":335217,"journal":{"name":"2009 International Conference on Embedded Software and Systems","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123261547","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}

For most elders, unpredictable falling accidents may occur at the corner of stairs or a long corridor due to body functional decay. If we delay to rescue a falling elder who is likely fainting, more serious consequent injury may happen. Traditional secure or video surveillance systems need someone to monitor a centralized screen continuously, or need an elder to wear sensors to detect accidental falling signals, which explicitly require higher costs of care staffs or cause inconvenience for an elder.In this work, we propose a human-shape-based falling detection algorithm and implement this algorithm in a multi-camera video surveillance system. The algorithm uses multiple cameras to fetch the images from different regions required to monitor. It then uses a falling-pattern recognition approach to determine if an accidental falling has occurred. If yes, the system will send short messages to someone needs to alert.In addition, we propose a multi-video-stream processing algorithm to speedup the throughput for the video surveillance system having multiple cameras. We partition the workloads of each video-surveillance streaming into four tasks: image fetch, image processing, human-shape generation, and pattern recognition. Each task will be handled by a forked thread. When the system receives multiple video streams from cameras, there are four simultaneous threads executed for different tasks. The objective of this algorithm is to exploit large thread-level-parallelism among those video-stream operations, and apply pipelining technique to execute these threads. All above algorithms have been implemented in a real-world environment for functionality proof. We also measure the system performance after multi-streaming speedup. The results show that the throughput can be improved by about 2.12 times for a four-camera surveillance system.","PeriodicalId":335217,"journal":{"name":"2009 International Conference on Embedded Software and Systems","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130006108","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}
