The effectiveness of a system to resolve this priority resides in its ability to logical assignment of the chance to transmit data width of the data, response to the interrupts etc. The purpose of this paper is to propose the scheme to implement reconfigurable architecture so that it can be interface with any common IP core of such a system using the specification of AMBA bus protocol. The scheme involves the typical AMBA features of 'single clock edge transition ', Split transaction ','several bus masters ', 'burst transfer '.The bus arbiter ensures that only one bus master at a time is allowed to initiate data transfers. Here we have proposed and implemented the reconfigurable arbitration algorithm, such as highest priority or fair access and round robin can be implemented depending on the application requirements. The design architecture is written using VHDL(Very High Speed Integrated Circuits Hardware Description Language) code using Xilinx ISE Tools. The architecture is modeled and synthesized using RTL(Register Transfer Level) abstraction and Implemented on Virtex2 series.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115044896","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}

Nath","doi":"10.1109/CSNT.2011.64","DOIUrl":"https://doi.org/10.1109/CSNT.2011.64","url":null,"abstract":"In the present work the authors have introduced a new method for hiding any encrypted secret message inside a cover file. For encrypting secret message the authors have introduced a new bit exchange algorithm. For hiding secret message Nath et al(1,2,3) have already proposed various methods. Here the authors modified the steganographic method. Instead of changing the LSB of the cover file at a stretch the authors proposed to change LSB and LSB+3 bits and changing alternate bytes of the cover file. It means to hide one byte of secret message the authors used 8 bytes of the cover file but out of 8 bytes 4 bytes were modified in LSB and LSB+3 bit positions and the alternate bytes remain unchanged. The secret message was encrypted by using a simple bit exchange method before the actual embedding process starts. The number of times the secret message to be encrypted using bit exchange method can be controlled by the user. The proposed bit exchange method is reversible that means the way the encryption done the decryption to be done in reverse way. The entire work was done in MATLAB. The authors applied the present steganography algorithm on different cover files such as image file, audio file, video file, word file, Excel file, Power point file,.exe file and in every case the result found was satisfactory. To embed any secret message inside a cover file the user has to enter a password and the same password to be used to unhide the secret message. The authors propose that this method could be most appropriate for hiding any file in any standard or non standard cover file such as word, excel, .ppt, .exe, image, audio, video files. The hidden message is encrypted using some bit exchange method and hence it will be almost impossible for the intruder to unhide the actual secret message from the embedded cover file. This method may be used for sending some secret key to someone over mail as the intruder may not be able to unhide and to decrypt the secret message.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131246016","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}

Sahare","doi":"10.1109/CSNT.2011.105","DOIUrl":"https://doi.org/10.1109/CSNT.2011.105","url":null,"abstract":"it is very difficult to understand speech signals in presence of background noise for the normal listeners and hearing impaired persons. The human speech and hearing organ is inherently sensitive to interfering noise. Interfering noise decreases speech intelligibility and quality which makes speech communication troublesome and causing human mistakes. Speech signals from the uncontrolled environments may contain degradation components along with the required speech components. Speech enhancement algorithms removes or reduces the noise and improve one or more perceptual aspects of noisy speech most notably quality and intelligibility. This paper reports a performance evaluation of Spectral subtraction algorithm and its modified versions for Hearing aids in different environments such as restaurant, train and Car environments. Clean speech signals are corrupted by background noise respectively multi-talker babble noise, train noise, and car engine noise at four different signal-to-noise ratio levels-2dB, 0dB, 5dB, 10dB. Subjective and objective type evaluation of enhanced speech signals were carried out. The evaluation of intelligibility and quality of enhanced speech is reported for hearing Aids. Section I introduction, section II explains basic block diagram of speech enhancement, explains basic Spectral subtraction speech enhancement algorithm in detail and its various modified versions of spectral subtraction algorithm, section III explains performance evaluation of this speech enhancement algorithms in terms of quality and intelligibility for Hearing aid, section-IV conclusion.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126832908","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}
