Data Storage costs have an appreciable proportion of total cost in the creation and analysis of DNA sequences. In particular, the increase in the DNA sequences is highly remarkable with compare to increase in the disk storage capacity. General text compression algorithms do not utilize the specific characteristics of DNA sequences. In this paper we have proposed a compression algorithm based on...

Color conversion model used in ICC specification is based on multi-dimensional look-up table and linear interpolation. This color conversion model is useful for device independent color reproduction. But in order to get a high spaed of color conversion for large image data, this interpolation needs simple calculation process. If non-linear interpolation smoothness will become better than simple...

When designing asynchronous systems, the problems of hazards becomes an important issue. This paper deals with the hazard-free implementation of asynchronous logic in a look-up table based FPGA. First, the definitions of hazards and techniques to deal with them in gate-level asynchronous circuits are surveyed. Then the look-up table (LUT) model and its associated timing properties are presented...

In this paper, a method of low power analog testing is proposed. In spite of having Oscillation Based Built in Self-Test methodology (OBIST), a look up table based (LUT) low power testing approach has been proposed to find out the faulty circuit and also to sort out the particular fault location in the circuit. In this paper an operational amplifier, which is the basic building block in the ana...

In industry, a feedback controller with look-up table (LUT) is often used for nonlinear systems. Although this structure easy to understand, tuning the LUT parameters time-consuming due huge number of parameters. This paper presents direct data-driven design method gain-scheduled directly tune from single-experiment data without system model. Specifically, conventional virtual reference (VRFT),...

Coastal area represents one of the more delicate and complex relation between natural environment and human activities. Remote sensing, offering considerable understanding of the temporal dynamics of bio-physical factors at different scale, represents a solution for monitoring the ecosystem. In particular marine phenomena, i.e. Sea Surface Temperature, chlorophyll concentration etc. can be rela...

The main objective is to design DA based adaptive filter in order to decreasing the logic complexity. Throughput is increasedby using parallel Look Up Table (LUT) update and concurrent implementation of filtering and weight-update operations.DA uses bitserial operations andlook-up tables (LUTs) to implement high throughput filters. Two smart LUT updating methods are developed, and least meansqu...

We focus on a recently proposed regression framework termed lattice regression, as applied to the construction of multidimensional color management look-up tables from empirical measurements. The key idea of lattice regression is that the construction of a look-up table should take into account the interpolation function used in its final implementation. Lattice regression solves for the look-u...

Abstract: Interpolator is an important sampling device used for multirate filtering to provide signal processing in wireless communication system. There are many applications in which sampling rate must be changed. Interpolators and decimators are utilized to increase or decrease the sampling rate. In this paper an efficient method has been presented to implement high speed and area efficient i...

This paper presents the theoretical basis of the algorithm designed for the generation of leaf area index and diurnal course of its sunlit portion from NASA's Earth Polychromatic Imaging Camera (EPIC) onboard NOAA's Deep Space Climate Observatory (DSCOVR). The Look-up-Table (LUT) approach implemented in the MODIS operational LAI/FPAR algorithm is adopted. The LUT, which is the heart of the appr...
