Binary field multiplication is the most fundamental building block of binary field Elliptic Curve Cryptography (ECC) and Galois/Counter Mode (GCM). Both bit-wise scanning and Look-Up Table (LUT) based methods are commonly used for binary field multiplication. In terms of Side Channel Attack (SCA), bit-wise scanning exploits insecure branch operations which leaks information in a form of timing ...

— This paper presents a new method of digital adaptive predistortion for linearization of Power Amplifiers (PA) exhibiting memory effects. The predistorter (PD) device consists of a Look-Up-Table (LUT) gain followed by a codebook of filters addressed by the index of the LUT. The adaptation is derived from direct learning for the LUT gains and indirect learning for the filter coefficients. We co...

We propose a fast alternative to B-splines in image processing based on an approximate calculation using precomputed B-spline weights. During B-spline indirect transformation, these weights are efficiently retrieved in a nearest-neighbor fashion from a look-up table, greatly reducing overall computation time. Depending on the application, calculating a B-spline using a look-up table, called B-L...

In this work, a study was carried out to estimate look-up table (LUT) that converts camera image plane birds eye view (BEV) using single camera. The traditional pose estimation fields require high costs in researching and manufacturing autonomous vehicles for the future may pre-configured infra. This paper proposes an vehicle driving calibration system is low cost utilizes A network outputs for...

This paper presents a method for operational testing of a memristor-based look-up table (LUT) memory block. In the proposed method the deterioration of the memristors (as storage elements of a LUT), is modeled based on the reduction of the resistance range, a phenomenon well known as reported in the technical literature. A quiescent current technique is used to diagnose the memristors when dete...

The FPGA (Field-Programmable Gate Array) has recently become the popular hardware and so-called LUTs (Look up Tables) are basic of FPGAs logic. For example, n-LUT is MOS pass transistors multiplexer 2n-1 which input data receive SRAM cells logic function configuration (user’s projects Truth Table). Address inputs LUT variables. Therefore, we get one n-arguments for actual configuration. To m fu...

This paper presents the realization of memory efficient architecture using Distributed Arithmetic (DA) for implementation of Finite Impulse Response (FIR) filter. Here, the multipliers in FIR filter are replaced with multiplier less DA based technique. First, the theory of DA is described. In this technique, pre-computed values of inner product are stored in LUT, which are further added and shi...

The Solar Diffuser (SD) is used for the MODIS reflective solar bands (RSB) calibration. An on-board Solar Diffuser Stability Monitor (SDSM) tracks the degradation of its on-orbit bi-directional reflectance factor (BRF). To best match the SDSM detector signals from its Sun view and SD view, a fixed attenuation screen is placed in its Sun view path, where the responses show ripples up to 10%, muc...

In polymer optical fiber (POF) systems, the nonlinear transfer function of the resonant cavity light emitting diode (RCLED) drastically degrades the communication performance. After investigating the characteristics of the RCLED nonlinear behavior, an improved digital look-up-table (LUT) pre-distorter, based on an adaptive iterative algorithm, is proposed. Additionally, the system parameters, i...
