Initially it was used in intelligent dictionaries and spell check applications. Its ability for dynamic membership querying and information compaction attracted huge research. Various optimization models of bloom filter for diverse applications were suggested and hence many bloom filter variants emerged. Network security has become an important factor in the recent years. In this paper, we propose a new variant of bloom filter in which a standard cryptographic hash function whirlpool is modified into a non cryptographic form and deployed in the bloom filter to improve the network security. We also suggest a suitable mapping scheme. A cryptographic hash function is one which converts an input data of arbitrary length into a fixed-length output. Bloom Filters are hash based structures which have a certain degree of accuracy for considerable savings in memory and are used to support membership queries. Bloom Filters allow probability of False Positive Ratios and the aim of this paper is to reduce FPR by modifying the structure of bloom filter and enabling it to operate in the increasing network speed. The design has been implemented and tested using a Xilinx 65 nm field programmable gate array as the target technology and the results are compared with replacing the housing unit with widely used universal H3 hash function and also relatively compared with the other possible hash functions and bloom filters in literature. The performance matrices of the proposed design are false positive ratio and speed. The design is hardware based and suitable for networking and security querying applications.","PeriodicalId":252016,"journal":{"name":"2014 2nd International Conference on Devices, Circuits and Systems (ICDCS)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131279407","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}

The discontinuities are abrupt changes in pixel intensity which characterize boundaries of objects in a scene. It plays a major role in many algorithms used for segmentation and tracking. This paper presents an edge detection algorithm that results in significantly reduced memory requirements, decreased latency and increased throughput with no loss in edge detection performance using MicroBlaze Processor.

It is desirable sometimes to be able to detect concealed weapons from a standoff distance, especially when it is impossible to arrange the flow of people through a controlled procedure. Therefore, we propose a novel algorithm to generate one multi exposed - multi modal image from a set of visual images with multiple exposures and a set of infrared images with multiple exposures. The method employs homomorphic filter, entropy of blocks and blending approach for image fusion. Experiments were performed on different sets of multi exposed images by varying the block size and the blending parameter which shows that the proposed method outperforms the results obtained without homomorphic filter.","PeriodicalId":252016,"journal":{"name":"2014 2nd International Conference on Devices, Circuits and Systems (ICDCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114221260","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}

There are several denominations of routing protocols available and the class of hybrid routing protocols are the ones that are the combos of two different genres of routing protocol. Though Low Energy Adaptive Clustering Hierarchy (LEACH) proves to be an outwitting routing scheme there are inherent limitations due to the power hungry overhead processing and the more number of participating nodes.

The controller is designed to interface DDR memory modules and memory ICs with low cost FPGAs and high clock frequency of 674.491 MHz at 28nm technology on Kintex 7 FPGA device with less logic utilization. The DDR controller makes many low level tasks invisible to the user like refresh, initialization and timings. It provides another layer of abstraction by optimizing memory access for maximum throughput or minimum latency. DDR controller provides the access of memory banks in parallel form, so it is required to being fast with less logic utilization. This paper optimizes the DDR SDRAM controller design by structural RTL level HDL Coding and modelling of SDRAM Initializing finite state machine (FSM). The results show 0.33% of slice utilization and 0.14% of LUT utilization is recorded at Xilinx Virtex 7 low voltage FPGA device. Due to RTL level optimization the route delay is just about 30% to 38 % as compare to that of logic delay. We also observe that the Kintex 7 Xilinx FPGA device has low offset input and output delay of the clock clk100 and clk200 of data path in this logic as compare to other FPGA devices. So hereby we proposed a DDR SDRAM controller which can work at high speed with less logic utilization and minimum logic, route and offset delay.","PeriodicalId":252016,"journal":{"name":"2014 2nd International Conference on Devices, Circuits and Systems (ICDCS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128686206","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}
