The objective of our article is to demonstrate that some physical defects in a LUT can change its propagation delay. We propose a simplified 'timing' model of the LUT which determines its propagation delay. Such a model is exploited to analyse the effects of a defect on the LUT behaviour, from which we demonstrate that they can cause a timing fault on it. Anywhere in a LUT, a timing defect can ...

The Fistulipora microparallela (Yang and Lu, 1962) species is described for the first time from the Sakmarian deposits of the Sarab section in Lut Block, Central Iran. This species has been reported only from the Permian (Cisuralian-Guadalupian) of the Qilianshan and Kankerin formations, and the Baliqliq Group (Upper Carboniferous to Lower Permian) of Western Xinjiang, China.

Vector quantization (VQ) is a powerful tool in signal processing. Hierarchical VQ (HVQ) is a method to implement VQ completely based on look-up tables (LUT). In HVQ, both encoders and decoders are inherently simple and fast, since there are no searches over codebooks. We introduce an overlapped HVQ (OHVQ) method, in which the number of samples is preserved after each HVQ stage. After the last s...

A Lookup‐Table (LUT) based design enhances the processing speed of a fuzzy obstacle avoidance controller by reducing the operation time. Also, a LUT sharing method provides efficient ways of reducing the LUT memory size. In order to share the LUT which is used for a fuzzy obstacle avoidance controller, an idea of using a basis function is developed. As applications of...

In this paper, VLSI implementations for the Triple-DES Block Cipher are presented. Triple-DES (TDES) is basically used in various cryptographic applications and wireless protocol security layers. Three different hardware implementations are proposed. The first two are based on the pipeline technique, while the third uses consecutive iterations for the data transformations. In addition, the used...

In this paper, memory optimization and architectural level modifications are introduced for realizing the low power <span lang="EN-US">residue number system (RNS) with improved flexibility electroencephalograph (EEG) signal classification. The proposed RNS framework is intended to maximize reconfigurability of high-performance finite impulse response (FIR) filter design. By replacing exis...

This paper shows a design method for a sequential circuit by using a Look-Up Table (LUT) ring. An LUT ring consists of memories, a programmable interconnection network, a feed-back register, an output register, and a control circuit. It sequentially emulates an LUT cascade that represents the state transition functions and the output functions. We present two algorithms for synthesizing a seque...

Recently we have applied Look Up Table (LUT) Method for inverse halftoning. We also proposed tree-structure LUT inverse halftoning in order to reduce memory requirements of the LUT method. In this paper we introduce LUT based halftoning method. Pixels from a causal neighborhood and the contone value of the current pixel will be included in the LUT. The LUT halftoning will require no arithmetic ...
