First, the theory of the distributed arithmetic is described. Furthermore, a modification of the DA based on the look up table (LUT) and filter structure to implement the high-order filter hardware-efficient on FPGA is introduced. The proposed filter has been designed and synthesized with ISE 7.1, and implemented with a 4VLX40FF668 FPGA device. Our results show that the proposed DA architecture can implement FIR filters with the smaller resource usage and similar speed in comparison to the previous DA architecture.","PeriodicalId":218351,"journal":{"name":"2007 International Conference on Communications, Circuits and Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121613750","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}

This research focus on generating a model in the form of a state machine to recognize strings derived from the direction information of character's images. The state machine induction process has two steps. The first step is to generate the machine from the strings of each target character (positive training), and the second step is to adjust the machine to reject any other string (negative training). This state machine induction method that automatically learns from strings can be applied with other string patterns recognition apart from characters.","PeriodicalId":218351,"journal":{"name":"2007 International Conference on Communications, Circuits and Systems","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126632919","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}

Using the high performance DSP system, two channel of image signal were collected, detected and tracked in real time and the experimental results were displayed.
