The focus is on the FPGA implementation of the digital PLL. The control is based on a closed loop, the sensing element being an optical tachometer. The output of the tachometer is compared to a reference signal, and a pulse width modulated (PWM) signal is derived, based on the phase and frequency error, to adjust the system output. The phase and frequency error is determined by a digital phase/frequency detector and is delivered as a PWM signal. This error signal is measured by the digital circuitry and passed to the loop filter of the PLL, which acts as the regulator. The main result is the phase error measurement circuitry. It has a numeric output, which allows the design of a digital loop filter. The design of the PLL can be done only with digital logic. The whole digital controller can be easily implemented in an FPGA.","PeriodicalId":371855,"journal":{"name":"2009 IEEE 5th International Conference on Intelligent Computer Communication and Processing","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125235227","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}

Such systems must evaluate the state of the world and take necessary actions. A preliminary step for evaluating the state of the world is to detect, track and classify scene objects. The classification step becomes especially important in complex urban traffic scenarios. In such scenarios the sensors of choice are vision based, as they provide detailed scene information. In this paper we present the architecture of a detection, tracking and classification framework based on stereovision. We detect objects using either a points grouping algorithm (for large objects) or a density map grouping algorithm (for small objects). We perform first a rough classification based on objects' dimensions and track objects according to the motion model of each class. We extract motion features and perform a refined classification. Class specific dichotomizers are subsequently used to filter the classified objects, rejecting incorrect classification. A large database of manually labeled objects is used for determining motion models, training the classifiers and measuring the performance of the system.","PeriodicalId":371855,"journal":{"name":"2009 IEEE 5th International Conference on Intelligent Computer Communication and Processing","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126377058","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}

Unfortunately, real-world systems do often not follow these requirements, or their architecture gets degraded in time by many ad-hoc changes. Consequently, these systems have to go frequently through the costly and oftentimes manually-performed operation of restructuring services and their inter-connections. This paper introduces a restructuring technique for distributed systems that supports an architect in performing a cost-aware analysis of various restructuring scenarios. The technique enables the engineer/architect to explore and evaluate the impact of the restructuring process at a fine-grained level, by providing both a forecast of the restructuring outcome, and the projected cost of the process itself. The approach described is mainly based on a suite of novel coupling metrics, a new algorithm that builds the forecast of the restructured architecture, and a formula for computing the cost. The approach was successfully applied on a commercial distributed framework implemented using RMI and in this paper we summarize the findings and the practical experience. Although the technique was developed for the specific case of distributed systems, we are confident that it can be easily generalized to a larger class of applications.","PeriodicalId":371855,"journal":{"name":"2009 IEEE 5th International Conference on Intelligent Computer Communication and Processing","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126459205","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}
