Analytical Estimation of Signal Transition Activity from WordLevel Statistics
 IEEE Trans. on CAD
, 1997
"... Presented in this paper is a novel methodology to determine the average number of transitions in a signal from its wordlevel statistical description. The proposed methodology employs: 1.) highlevel signal statistics, 2.) a statistical signal generation model, and 3.) the signal encoding (or num ..."

DESIGN OF LINEARPHASE FIR FILTERS WITH MINIMUM HAMMING DISTANCE
"... In this paper a new approach for the design of linear phase FIR filters with discrete coefficients is proposed. A mixed integer linear programming (MILP) problem is formulated that minimizes the total Hamming distance between the adjacent coefficients, i.e., the number of bit switches of the coeffic ..."

Avoiding adjustments in modular computations
, 2012
"... We consider a sequence of operations (additions, subtractions, multiplications) modulo a fixed integer N, where only the final value is needed, therefore intermediate computations might use any representation. This kind of computation appears for example in number theoretic transforms (NTT) [2], in ..."

, we measure the average number of adjustment steps for each addition (or subtraction) and each multiplication. We assume the number N is stored on n machine words, and residues modulo N are stored in a signmagnitude representation, as in GMP [1]. We denote by β the smallest power of the word base
CADRE: A LowPower, LowEMI DSP Architecture for Digital Mobile Phones
"... Current mobile phone applications demand high performance from the DSP, and future generations are likely to require even greater throughput. However, it is important to balance these processing demands against the requirement of low power consumption for extended battery lifetime. A novel lowpower ..."

A RiskFactor Model Foundation for RatingsBased Bank Capital Rules

When economic capital is calculated using a portfolio model of credit valueatrisk, the marginal capital requirement for an instrument depends, in general, on the properties of the portfolio in which it is held. By contrast, ratingsbased capital rules, including both the current Basel Accord and its proposed revision, assign a capital charge to an instrument based only on its own characteristics. I demonstrate that ratingsbased capital rules can be reconciled with the general class of credit VaR models. Contributions to VaR are portfolioinvariant only if (a) there is only a single systematic risk factor driving correlations across obligors, and (b) no exposure in a portfolio accounts for more than an arbitrarily small share of total exposure. Analysis of rates of convergence to asymptotic VaR leads to a simple and accurate portfoliolevel addon charge for undiversified idiosyncratic risk. There is no similarly simple way to address violation of the single factor assumption.
RedundantDigit FloatingPoint Addition Scheme Based on a Stored Rounding Value

We propose a new redundantdigit representation for floatingpoint numbers that leads to computation speedup in two ways: 1) Redu ..."
