A way to speed up the adders is to eliminate carry propagation by using carry-free adders. In this paper we improve the fastest previous carry-free adder by changing the transfer digit-set to [-2,1]. It is shown that this small change leads to a simpler signed-digit adder which consumes lower area/power than the fastest previous work while not increasing the latency.","PeriodicalId":276803,"journal":{"name":"2012 International Symposium on Electronic System Design (ISED)","volume":"90 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134162600","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}

Unlike many other reported techniques, our method is able to handle code motions across loop bodies. This is accomplished by repeated propagation of the mismatched values to subsequent paths until the values match or the final path segments are traversed without finding a match. Checking loop invariance of the values being propagated beyond the loops has been underlined to play an important role. The proposed method is capable of handling control structure modification as well. The method has been implemented and satisfactorily tested for some benchmark examples.","PeriodicalId":276803,"journal":{"name":"2012 International Symposium on Electronic System Design (ISED)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134420404","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 unspecified bits in the test cubes are filled with the logic value of 1's or 0's using the proposed don't care filling technique, namely CSP - filling in such a way that the both average power and peak power in test applications are reduced. In our approach, the capture transition is made to be within the peak-power limit of the circuit under test while reducing the average power in shift-in phase of test applications.

The main contributions of this paper are the improved finite field multiplier, which uses a 2-stage Karatsuba-Ofman multiplier architecture. Furthermore, a revised algorithm is proposed for the projective to affine coordinate conversion, which computes 2 inversion operations simultaneously with the numerator portion, in order to make better use of parallel cores implemented in the ECC processor. The design is implemented on a Virtex 4 XC4VLX80 FPGA and the implementation results show that the ECC processor can compute a point multiplication in 6.72 us. This time is the fastest to the authors' best knowledge. Thus, the ECC processor proposed in this paper is suitable for applications where high-throughput is required, such as network servers.","PeriodicalId":276803,"journal":{"name":"2012 International Symposium on Electronic System Design (ISED)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127786726","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}

At the present age, elimination of harmonics produced by the nonlinear loads to improve the power quality is a great issue. To overcome the problem due to harmonics, Active Power Filters (APFs) are used with various control schemes. But Hybrid Active power filter is a power electronic device which has both the characteristics of passive power filters and active power filters, helps in cancelation of the harmonics by producing compensating signal.

The proposed partitioning scheme partitions middle of range either horizontally or vertically to create to sub-ranges if the range is not covered well by any domain. The decision to select one of the two possibilities i.e. horizontal or vertical partitioning is done only by a simple checking which side of the range is larger than the other. It does not depend on the context of the range to compute the partitioning point that speed up the partitioning. One variant of the same is also proposed where the decision to select one of the two sides of range is done by computing the pixel value differences of the middle vertical lines and the middle horizontal lines and determining which is greater than other. The fractal image compression for grey scale image with the proposed partitioning schemes offer better compression rates than the quadtree partitioning scheme maintaining almost same compression times with improved PSNRs. Though the compression rates are not as well as offered by HV partitioning scheme, the proposed schemes are much faster than the same.","PeriodicalId":276803,"journal":{"name":"2012 International Symposium on Electronic System Design (ISED)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124038544","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}
