We introduce a retargetable microcode generator for application specific digital signal processors (ASDSPs). The primary goal of our work is to quickly provide system architects with the set of tools necessary for program development (assemblers, instruction set simulators, debuggers and compilers); in particular when the processor architecture is refined simultaneously with the algorithm. Afte...

The problem of the relevance and the usefulness of extracted association rules is becoming of primary importance, since an overwhelming number of association rules may be derived even from reasonably sized databases. This requires the extraction of generic bases of association rules, of reduced size and which summarize the same information. Using the concept of minimal generator, we propose an ...

Starting with a symmetric Markov diffusion process X (with symmetry measure m and L(m) infinitesimal generator A) and a suitable core C for the Dirichlet form of X, we describe a class of derivations defined on C. Associated with each such derivation B is a drift transformation of X, obtained through Girsanov’s theorem. The transformed process X is typically non-symmetric, but we are able to sh...

The problem of the relevance and the usefulness of extracted association rules is becoming of primary importance, since an overwhelming number of association rules may be derived, even from reasonably sized databases. To overcome such drawback, the extraction of reduced size generic bases of association rules seems to be promising. Using the concept of minimal generator, we propose an algorithm...

The basis for a hydrodynamic description of granular gases is discussed for a low density gas of smooth, inelastic hard spheres. The more fundamental mesoscopic description is taken to be the nonlinear Boltzmann kinetic equation. Two arguments are presented in favor of a hydrodynamics for granular gases. The first one is the concept of a ”normal” solution and its explicit approximate constructi...

This paper describes the design and implementation of an interactive, incremental-attribution-based program transformation system, CACHET, that derives incre-mental programs from non-incremental programs written in a functional language. CACHET is designed as a programming environment and implemented using a language-based editor generator, the Synthesizer Generator , with extensions that suppo...

In this paper, a brief summary of synchronization approaches is discussed sequentially from older techniques to latest technology. There are many techniques that have been developed which focusing of synchronization, from basic grid evaluating technique, phase-locked-loop (PLL) and later to synchronous reference-frame phase-locked-loop where is established on basis of phase estimation and deter...

We study the suitability of common pseudorandomness modes associated with cryptographic hash functions and block ciphers (CBCMAC, Cascade and HMAC) for the task of “randomness extraction”, namely, the derivation of keying material from semi-secret and/or semirandom sources. Important applications for such extractors include the derivation of strong cryptographic keys from non-uniform sources of...
