Pseudo random numbers are used in a number of areas such as cryptography and scientific and statistical simulation. Random numbers are crucial in statistics to obtain a uniform distribution for the prior knowledge and integration of Monte Carlo methods in statistical signal processing. In this paper, we propose a new random number generator using permutation matrices. This algorithm has three m...

Paper is devoted to a design FPGA problem regarding increase in trustworthiness of the results calculated in digital components of computer systems. The modern CAD solves this problem by implementation of significant hardware redundancy in fault tolerant decisions. The method for increase in trustworthiness of the results calculated on FPGA with the LUT-oriented architecture is offered. This me...

Chromatic dispersion is one of the most significant impairments in long-distance fiber-optical communications. Electrical domain compensation of optical chromatic dispersion by signal predistortion using digital processing is investigated with two different approaches: using a linear digital FIR compensating filter and using a nonlinear filter based on a look-up table (LUT). The linear compensa...

OBJECTIVES Dementia with Lewy bodies (DLB) is the second most common degenerative cause of dementia, whereas lower urinary tract (LUT) function in DLB patients has not been fully delineated. We investigated LUT function in DLB by clinical-urodynamic observations. METHODS We examined 32 patients with DLB (23 men, 9 women; aged 59-86 [mean, 75.9] years; disease duration, 0.2-17 [3.3] years). Al...

The paper proposes the technology of control of integrity and legitimacy of information object usage with the Look Up Table-oriented (LUToriented) architecture. The technology is based on embedding the self-recovery digital watermark into information objects of such kind. The technology is the composition of approaches to forming the self-recovery digital watermarks in the passive multimedia co...

This paper studies joint security and robustness enhancement of quantization-based data embedding for multimedia authentication applications. We present analysis showing that through a lookup table (LUT) of nontrivial run that maps quantized multimedia features randomly to binary data, the probability of detection error can be considerably smaller than the traditional quantization embedding. We...

We present analysis showing that through a lookup table (LUT) of non-trivial run that maps quantized multimedia features randomly to binary data, the detection error probability can be considerably smaller than the traditional quantization embedding.

A multiple-output function can be represented by a binary decision diagram for characteristic function (BDD for CF). This paper presents a method to represent multiple-output incompletely specified functions using BDD for CFs. An algorithm to reduce the widths of BDD for CFs is presented. This method is useful for decomposition of incompletely specified multiple-output functions. Experimental r...

The use of Look-Up Tables (LUTs) is extended from binary to multiple-valued logic (MVL) circuits. A multiple-valued LUT can be implemented using both current-mode and voltage-mode techniques, reducing the transistor count to half compared to that of a binary implementation. Two main applications for multiple-valued LUTs are multiple-valued FPGAs and intelligent memories. An FPGA uses a LUT as a...
