Low-cost finite impulse response (FIR) designs are presented using the concept of faithfully rounded Booth multipliers. We jointly consider the optimization of bit width and hardware resources without sacrificing the frequency response and output signal precision. Non-uniform coefficient quantization with proper filter order is proposed to minimize total area cost. Multiple constant multiplicat...

DSP applications are rich in multiplication operations. Hence there is a growing need in improving the efficiency of multipliers. To improve the performance of multipliers, reconfiguration is introduced. In this paper, reconfiguration is introduced in the form of one level recursive architecture to the existing modified booth multiplier (MBM). It provides reconfigurable modes that satisfy multi...

Approximate computing is an attractive design methodology to achieve low power, high performance (low delay) and reduced circuit complexity by relaxing the requirement of accuracy. In this paper, approximate Booth multipliers are designed based on approximate radix-4 modified Booth encoding (MBE) algorithms and a regular partial product array that employs an approximate Wallace tree. Two approx...

Ken Kunen is justifiably best known for his work in set theory and topology. What I would guess many of his friends and students in those areas do not know is that Ken also did important work in algebra, especially in quasigroup and loop theory. In fact, I think it is not an exaggeration to say that his work in loop theory, both alone and in collaboration, revolutionized the field. In this pape...

I think analogy is one of the core operations in human cognitive processing. There is evidence that the principles of Gentner‘s structure-mapping theory are applicable from mediumlevel vision to everyday reasoning to cognitive development to scientific discovery. That‘s quite a range of phenomena. Our computational modeling efforts do not yet span anything close to that range. But that‘s one of...

0740-7475/98/$10.00 © 1998 IEEE 105 MODULE GENERATORS PROVIDED by library vendors supply chip designers with optimized Booth multipliers, which are widely used as embedded cores in both generalpurpose data path structures and specialized digital signal processors. Designers frequently use Booth multipliers in areaand speedcritical parts of complex ICs. Compared to standard array multipliers, Bo...

Abstract This study presents new data on the bi-absolutive construction in Chechen, a Nakh-Daghestanian language spoken northern Caucasus. The basic case frame transitive clause Chechen is ergative-absolutive. In progressive constructions with an auxiliary and simultaneous converb, alternates absolutive-absolutive – or construction. To assess factors conditioning this alternation, we use from t...
