In particular, the queries are seen as integrating rules built with operations provided by the connectives of bilattices. An important aspect arising in the context of query evaluation is its efficiency, therefore we equally tackle the problem of query equivalence, which traditionally constitutes one of the central problems in query optimization. The paper provides results that characterize the query containment and equivalence problems syntactically, which naturally lead to algorithms for testing for equivalence of queries integrating imperfect information in the context of bilattices. Finally we study the complexity of query equivalence and the data complexity of query evaluation.","PeriodicalId":447743,"journal":{"name":"2010 40th IEEE International Symposium on Multiple-Valued Logic","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115131888","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}

A Differential-Pair Circuit (DPC) is used as a basic component of a cell, so that the static power is dissipated even in the nonactive cells. To solve the problem, autonomous ON/OFF control of the current sources is presented based on superposition of bit-serial data and current-source control signals. In the proposed switched current control technique, the static power dissipation can be greatly reduced because current sources in nonactive circuit blocks are turned off. The superposition of data and control signals in a single interconnection is effectively utilized to reduce complexity of switches and interconnections, and to eliminate skew between data and control signals. It is evaluated that the reduction of the power dissipation is remarkable, if the operating ratio is less than 75%.","PeriodicalId":447743,"journal":{"name":"2010 40th IEEE International Symposium on Multiple-Valued Logic","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123189014","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 MMD algorithm requires to store a truth table (or a Reed-Muller -RM transform) as a 2^n vector for a reversible function of n variables. This representation prohibits synthesis of large functions. However, in MP we do not store such an exponentially growing data structure. The values of minterms are calculated in MP dynamically, one-by-one, from a set of logic equations that specify the reversible circuit to be designed. This allows for synthesis of large scale reversible circuits (30-bits), which is not possible with existing algorithms. In addition, our unique multipass approach where the circuit is synthesized with various, yet specific, minterm orders yields optimal solution. The algorithm returns a description of the optimal circuit with respect to gate count or quantum cost. Although the synthesis process is relatively slower, the solution is found in real-time for smaller circuits of 8 bits or less","PeriodicalId":447743,"journal":{"name":"2010 40th IEEE International Symposium on Multiple-Valued Logic","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127787254","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}

We show that dynamic power consumption in stochastic decoders is exposed at the algorithmic level and can be evaluated from the values of messages passed on the code’s factor graph. This observation leads to a method for evaluating the relative dynamic power consumption of stochastic decoders as early as the code design stage. We propose a method based on density evolution that can be used to compare code ensembles in terms of their decoding energy per information bit. We note that despite using a stochastic signaling scheme, stochastic decoders converge to a codeword and stop consuming dynamic power. Results illustrate that significant differences in power consumption can be identified at the code design stage and tradeoffs can be exploited before designing a specific implementation.","PeriodicalId":447743,"journal":{"name":"2010 40th IEEE International Symposium on Multiple-Valued Logic","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127483511","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}

In contrast to conventional 1bit/step SA ADCs, 2bit/step conversion is employed, and combined with the split capacitor array and dual sampling technique to reduce the power consumption. Transistor level simulation, assuming 0.18-µm standard CMOS technology, shows that the total power consumption decreases by about 20% compared with that obtained for a 1bit/step counterpart at a sampling frequency of 100 kHz. Since the digital part consumes more power than the analog part, the present approach is expected to be more attractive for ADCs using advanced process technology.","PeriodicalId":447743,"journal":{"name":"2010 40th IEEE International Symposium on Multiple-Valued Logic","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125758866","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}
