But even with the rapid development of large-scale integrated circuit, it is usually impractical to implement these floating-point computations on FPGA, as they will consume a large amount of chip resources. In this paper, a compact SAR processor, composed of four 1D FFT-PEs (processing elements) and a CORDIC co-processor, is implemented on FPGA. In particular, a dynamic configurable pipeline is used in FFT-PE to reduce the area consumption through reusing floating-point units. And the 32-bit floating-point hybrid-mode CORDIC co-processor is implemented to generate compensation factors and compute transcendental functions in SAR image visualization phase. Experimental results show that our SAR processor performs well both in area and latency. It consumes about 40% of LUTs and DSPs, and about 48% of memory bits on a StratixII FPGA. Moreover, 32-bit floating-point hybrid-mode CORDIC co-processor only occupies about 2.6% LUTs and Registers of Virtex5 and achieves a clock frequency of 217 MHz. Regarding the latency, it takes 1232.6 ms to transform the SAR raw data of 4K*4K into a visible image of 256 grey levels and can meet the real-time requirement.","PeriodicalId":278372,"journal":{"name":"2008 International Conference on Embedded Software and Systems","volume":"259 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134192022","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}

Some existed medium access protocols and algorithms can effectively prolong the lifetime of the sensor network by determining when each sensor should transmit its data, and when it should sleep. In this paper, we focus on applying multiple spanning trees to organize the data aggregation, which is different from these existed single spanning tree methods. At first, the problem of constructing multiple spanning trees is transformed into a linear programming problem of the data flow network. Based on the solved optimal rate between the two adjacent sensors, the two constructing algorithms of the spanning tree are presented. Experimental results indicate that the method of multiple spanning trees can be of benefit to energy saving for wireless sensor networks, and the corresponding appropriate constructing algorithm can prolong the lifetime of the sensor network.","PeriodicalId":278372,"journal":{"name":"2008 International Conference on Embedded Software and Systems","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127467592","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}

Because such devices are usually fixed in some locations in the physical environment and canpsilat move by themselves, they can only sense information or act only in specific locations/directions. Different from these devices, are robots which can carry sensors and/or actuators, and are capable of moving from one location to another in a space. Because of their capability to move, robots can therefore be utilized to add flexible location-related service functions to smart spaces. To realize these new functions, robots must collaboratively work with a smart space manager and other devices/u-objects in the space. This paper presents the design and development of a system prototype with multiple robots with focus on how to manage the multiple robots and their collaborative work in finding RFID tagged u-objects in a smart room. Some experiments have been conducted and the result verifies and evaluates the aforementioned functionalities.","PeriodicalId":278372,"journal":{"name":"2008 International Conference on Embedded Software and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131331312","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}
