We present an equivalent pipelined PWM architecture working to provide the highest throughput up to date through inserting some registers in appropriate points making the delay shortest, when implementing the byte transformation in one clock period. The register is included in the final stage of both existing and proposed architecture. Higher density programmable logic device such as FPGA[1] can be used to integrate large amounts of logic in a single IC. FPGA becomes one of the most successful of technologies for developing the systems which require a real time operation. Pulse width modulation (PWM) has been widely used in power converter control. The proposed PWM generation unit is based on a specially designed with pipelined, synchronous binary counter, resulting in maximum PWM frequencies with a lower delay. So the speed will be increase. While the PWM unit can be easily interfaced to a microcontroller or DSP system. The contribution of this paper is the development of high frequency PWM generator architecture for power converter control using FPGA. The resulting PWM frequency depends on the target FPGA device speed grade and the duty cycle resolution requirements.","PeriodicalId":242568,"journal":{"name":"2013 International Conference on Current Trends in Engineering and Technology (ICCTET)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133434821","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 main goal of this paper is developing a new watermarking scheme with high copyright protection. In order to achieve this in existing system employed fuzzy watermarking system by means of wavelet technique where they have realized with two phases. One is the embedding phase where the host image was embedded with the watermark image with a secret key; the LSB (Least Sigraficant Bit) technique is utilized to get the watermarked image. Second phase was extraction phase in which the watermarked image (output of first phase) which was decomposed by using Haar wavelet transform. In proposed work with the purpose of improving the embedding phase, developed an improved algorithm with the block based error correcting coding and DWT watermarking which is applied on digital images. This work presenting a novel technique based on convolutional code to improve the robustness of the embedded watermark. The watermarking is preferred in low frequency band of the Discrete Wavelet Transform (DWT) and as a result it can refuse to accept the destruction of image processing. The Haar wavelet filters are preferred for the DWT decomposition to give recovered outcome in embedding process. Here the embedding process is done using the weighted addition rule were essentially considering the case where the host image was obtainable at the extraction, and so, host intrusion was not a problem. When we apply Inverse Discrete Wavelet Transform (IDWT) at the extraction phase the watermarked image will be retrieved. The performance of purposed watermarking method is estimated with the parameters of PSNR, MSE, SSIM, Correlation, and Entropy. Experimental results show that this proposed watermarking technique is more robust than the existing method.","PeriodicalId":242568,"journal":{"name":"2013 International Conference on Current Trends in Engineering and Technology (ICCTET)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131785839","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}
