In this paper the testability of modified-Booth array multipliers for standard cells based design environments is examined for first time. In such cases the structure of the cells may be unknown, thus Cell Fault Model (CFM) is adopted. Two C-testable designs are proposed. A design for an Nx x Ny bits modified-Booth multiplier, which uses ripple carry addition at the last stage of the multiplica...

There are now several experimental collaborations that have seen evidence for a narrow state in the mass spectrum of the (nK) system. Two of these experiments, from the LEPS collaboration in Japan and the CLAS collaboration in the USA, are described briefly. Both use similar photoproduction reactions with a KK pair in the final state. In addition, data from the CLAS collaboration for the γp→ Ks...

The main result of this paper is the development of a low depth cany lookahead addition technique based on threshold logic. Two such adders are designed using the recently proposed charge recycling threshold logic gate. The adders are shown to have a very low logic depth, and significantly reduced area and power dissipation compared to other dynamic CMOS implementations.

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...

Using a simple on-the-spot approximation, we explore the parameter range in the (log(R), log(ne)) plane for which maser action in atomic hydrogen is present and briefly discuss how the borderlines of this region of strong population inversion arise. In particular we address the influence of radiative transfer on the population structure. We find that in normal HII regions no strong maser activi...

Let a be an l-sequence generated by a feedback-with-carry shift register with connection integer q = pe, where p is an odd prime and e 1. Goresky and Klapper conjectured that when pe = 2 f5; 9; 11; 13g, all decimations of a are cyclically distinct. When e = 1 and p > 13, they showed that the set of distinct decimations is large and, in some cases, all deciamtions are distinct. In this article, ...

We introduce arc-lh, a new algorithm for improvement of ANN clas-siier performance, which measures the importance of patterns by aggregated network output errors. On several artiicial benchmark problems, this algorithm compares favorably with other resample and combine techniques.

We present lookahead widening, a novel technique for using existing widening and narrowing operators to improve the precision of static analysis. This technique is both self-contained and fully-automatic in the sense that it does not rely on separate analyzes or human involvement. We show how to integrate lookahead widening into existing analyzers with minimal effort. Experimental results indic...

ÐInteger addition is one of the most important operations in digital computer systems because the performance of processors is significantly influenced by the speed of their adders. This paper proposes a self-timed carry-lookahead adder in which the logic complexity is a linear function of n, the number of inputs, and the average computation time is proportional to the logarithm of the logarith...
