Novel gate level synthesis of robust asynchronous carry lookahead adders based on the notion of section carry is discussed in this paper. For a range of higher order addition operations, the carry lookahead adder is found to exhibit reduced latency than the carry ripple version by 38.6%. However, the latter occupies less area and dissipates less power compared to the former by 37.8% and 17.4% r...

In this paper, we propse 16-bit sparse tree RSFQ adder (Rapid single flux quantam), kogge-stone adder, carry lookahead adder. In general N-bit adders like Ripple carry adder s(slow adders compare to other adders), and carry lookahead adders(area consuming adders) are used in earlier days. But now the most of industries are using parallel prefix adders because of their advantages compare to kogg...

-The saying goes that if you can count, you can control. Addition is a fundamental operation for any digital system, digital signal processing or a control system. A fast and accurate operation of a digital system is greatly influenced by the performance of resident adders. In this regard, an efficient hybrid adder that combines a carry select adder and a ripple carry adder using QCA technology...

The pipeline technique applied to implement a group half (HA) blocks architect the proposed adder. pipelined carry (PCA) method suitable for carrying out desired by using HA circuits XOR and AND gates. reduces critical path delay 27% compared with ripple (RCA) relatively lowers logic gates 55% loo...

One of the central problems in the eld of knowledge discovery is the development of good measures of in terestingness of discovered patterns Such measures of interestingness are divided into objectivemeasures those that depend only on the structure of a pat tern and the underlying data used in the discovery process and the subjective measures those that also depend on the class of users who exa...

Adding examples of the majority class to the training set can have a detrimental eeect on the learner's behavior: noisy or otherwise unreliable examples from the majority class can overwhelm the minority class. The paper discusses criteria to evaluate the utility of clas-siiers induced from such imbalanced training sets, gives explanation of the poor behavior of some learners under these circum...

In asynchronous systems, average function delays principally govern overall throughput. This paper compares the performance of six adder designs with respect to their average delays. Our results show that asyn-chronous adders (32 or 64-bits) with a hybrid structure (e.g., carry-select adders) run 20-40% faster than simple ripple-carry adders. Hybrid adders also outper-form high-cost, strictly s...
