Two types of programmable logic devices using LUTs (Look-Up Tables) are presented. An LUT cascade directly implements logic functions by a series connection of LUTs, while an emulator emulates an LUT cascade by sequentially accessing LUTs. The LUT cascade is faster, but has a limited logic capability, while the emulator is slower, but has a higher logic capability. LUT cascades and emulators ca...

In industry, gain-scheduled proportional-integral-derivative (PID) control is performed for nonlinear systems using a look-up table (LUT) that easy to understand. Compared with the fixed PID, there are many more parameters of scheduler, and it takes lot time tune them. Also, ROM storage area increases. To address these problems, in this paper, we propose law sparse polynomial functions direct p...

A critical step in the product generation of satellite or airborne earth observation data is the correction of atmospheric features. Due to the complexity of the underlying physical model and the amount of coordinated effort required to provide, verify and maintain baseline atmospheric observations, one particular scientific modelling program, MODTRAN, whose ancestor was first released in 1972,...

Binary MQ arithmetic coding is widely used as a basic entropy coder in multimedia system. esteems high compression efficiency to be JBIG2 and JPEG2000. The importance of increasing after it adopted unique HEVC standard. In the binary coder, approximation without multiplication process recursive subdivision range interval. Because MPS/LPS exchange activity that happens output byte tends increase...

In this paper, an efficient algorithm for optimizing the size of a LUT required for the direct storage of complex computational values and a FIR System based on optimized LUT is implemented. So far, many algorithms have been implemented for optimizing Look-up-tables (substitute the multiply and accumulate structures contained in FPGAs) of DSP cores in FPGAs. In this paper, a new method “A-OMS L...

Imaging sensors are linear over a large part of their operational range. Nevertheless, behavior becomes non-linear when approaching saturation. This is undesired if such used for scientific measurements. In this work, simple and efficient off-chip method proposed image sensor linearization. First, the response characterized with constant irradiance sequence captures at several integration times...

The critical heat flux (CHF) is an important thermal-hydraulic parameter that must be determined during the design of water-cooled reactors to ensure safety operation. In this paper, a methodology proposed predict CHF in VVER rod bundles. A whole-reactor model VVER-1000 implemented RELAP-SCDAPSIM, and, based on bundle-average approach, parameters hot channel are used assess four predictors (i.e...

The Chinese environmental satellites HJ1 A and B can play a significant role in the aerosol retrieval due to their high spatial and temporal resolution. The current Aerosol Optical Depth (AOD) retrieval methods from HJ1-CCD are almost based on the LUT (Look-Up Table), by selecting the best fitting result to determine the AOD. However, aerosol model selection has an important impact on the retri...

A system-optimized framework is presented for learning a multi-dimensional look-up-table (LUT) from training samples. The technique, termed lattice regression, solves for an entire LUT at once by optimizing the three-fold objective of 1) low interpolation error on training data, 2) smooth transitions between adjacent LUT outputs, and 3) a steady overall functional trend. The proposed algorithm ...
