We investigate their suitability for low energy applications, where long battery life and delay tolerance is the principal design goal, and where performance is not a critical requirement. Three adder circuits are studied -two dynamic and one based on pass-transistor logic. All adders combine dual-rail and bundled-data circuits. The circuits are simulated at a wide supply-voltage range, down to their minimal operating point. Leakage energy (at 0.18 /spl mu/m) is found to be negligible. Transistor count is found to be an unreliable predictor of energy dissipation. Keepers in dynamic logic are eliminated when possible. The least amount of energy is dissipated by a modified version of a two-bit dynamic adder originally proposed by K.S. Chong et al. (see Int. Symp. Circuits and Systems, 2002).","PeriodicalId":38467,"journal":{"name":"Giornale di Storia Costituzionale","volume":"34 1","pages":"164-167"},"PeriodicalIF":0.0,"publicationDate":"2004-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88042806","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}

High programmability resolution is obtained by using a non-uniform sampling scheme without modifying any capacitor value. As a result, capacitor spread and total capacitor area are reduced as compared to traditional solutions and, hence, test area overhead can be minimized. To prove the feasibility of the proposed approach, the design and the implementation of a 0.35 /spl mu/m CMOS SC spectrum analyzer are discussed. Simulation results confirm that high measurement accuracy can be achieved.","PeriodicalId":38467,"journal":{"name":"Giornale di Storia Costituzionale","volume":"8 1","pages":"595-598"},"PeriodicalIF":0.0,"publicationDate":"2004-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87002804","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 LURU algorithm maps a combinational circuit to a network of K-input lookup tables (LUTs). The LURU algorithm uses content addressable memory (CAM) to enable parallel pattern matching in a Boolean network. As a result, it is possible to perform global searches quickly within an entire Boolean network, thus increasing the quality of results compared to algorithms of local scope. To utilize CAM for the LURU algorithm, a circuit is described as a set of one dimensional text strings, each of which independently represents the topology of a portion of the circuit. The LURU algorithm was tested with specially partitioned circuits from the ISCAS'85 set of combinational benchmarks. These results are compared with results obtained from the mapping algorithms FlowMap and CutMap. It is demonstrated that using LURU leads to an average of 25% area improvement over both FlowMap and CutMap.","PeriodicalId":38467,"journal":{"name":"Giornale di Storia Costituzionale","volume":"1 1","pages":"599-602"},"PeriodicalIF":0.0,"publicationDate":"2004-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82976670","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}

For a planar surface viewed through a pinhole camera undergoing translational and rotational motion, registration can be obtained via a projective transformation. For an acoustic camera, we show that, under the same conditions, an affine transformation is a good approximation. We propose a novel image fusion, which maximizes the signal-to-noise ratio of the mosaic image. The full procedure includes illumination correction, feature based transformation estimation, and image fusion for mosaicing.","PeriodicalId":38467,"journal":{"name":"Giornale di Storia Costituzionale","volume":"1 1","pages":"527-530"},"PeriodicalIF":0.0,"publicationDate":"2004-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81583603","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 design and synthesis of the target architectures are presented and compared for scalability and achieving parallelism. The performance and chip utilization of a shared register file is examined for different numbers of VLIW processing elements. The associated compilation flow is described based on the Trimaran VLIW compiler which achieves explicitly parallel instructions from C code.
