We present a disk array organization that adapts itself to successive disk failures. When all disks are operational, all data are mirrored on two disks. Whenever a disk fails, the array reorganizes itself, by selecting a disk containing redundant data and replacing these data by their exclusive or (XOR) with the other copy of the data contained on the disk that failed. This will protect the arr...

Abstract−This paper describes a new redundant fault identification algorithm with Exclusive-OR circuit reduction. The experimental results using this algorithm with a FAN-based test pattern generation algorithm show nearly 100% fault coverage for complex arithmetic logic circuits. Moreover we achieved 99.99% fault coverage applying this algorithm with a weighted random pattern generator to the ...

We show that for any Boolean function f : {0, 1} → {0, 1}, the bounded-error quantum communication complexity Q (f ◦ ⊕) of XOR functions f(x ⊕ y) satisfies that Q (f ◦ ⊕) = O ( 2 ( log ‖f̂‖1, + log n ) log(1/ ) ) , where d = deg2(f) is the F2-degree of f , and ‖f̂‖1, = ming:‖f−g‖∞≤ ‖ĝ‖1. This implies that the previous lower bound Q (f ◦ ⊕) = Ω(log ‖f̂‖1, ) by Lee and Shraibman [LS09] is tight for ...

In this paper, we investigate the dynamic behavior of a backpropagation neural network while learning the XOR-boolean function. It has been shown that the backpropagation algorithm exhibits chaotic behavior and this implies an highly irregular and virtually unpredictable evolution. We study the chaotic behavior as learning progresses. Our investigation indicates that chaos appears to diminish a...

Single-electron transistors (SETs) are sub-10-nm scale electronic devices based on conductive Coulomb islands sandwiched between double-barrier tunneling barriers. Chemically assembled SETs with alkanethiol-protected Au nanoparticles show highly stable Coulomb diamonds and two-input logic operations. The combination of bottom-up and top-down processes used to form the passivation layer is vital...

Exclusive-OR (XOR) operation plays an important role in the hardware implementation of many cryptographic algorithms. Since the hardware implementation of XOR gate is vulnerable to side channel analysis such as power analysis attacks, efficient countermeasures are required. The existing approaches provide countermeasures by placing more number of transistors at key locations in the gate impleme...

the security data transmission algorithm in cryptography is Advanced Encryption Standard (AES). The operation mix column consumed more power in the algorithm. In this paper the power consumption of mix column is reduced in order to achive the total power consumption of AES. Using a simple exclusive OR gate that is XOR gate pass transistor logic, the power can be minimized when compare to the ot...

We report a prototype of high-speed real-time physical random bit generator based on a chaotic laser. The chaotic laser consists of a semiconductor laser with optical feedback in fiber external cavity configuration. The chaotic laser intensity signal is quantized into binary stream by differential comparison which makes the amplitude distribution symmetric with respect to zero mean value. An ex...

In this report, we describe a novel application of the Baker’s map. We demonstrate that the chaotic properties of this map can be used to implement basic operations in Boolean logic. This observation leads naturally to the possibility of new computational models and implementations for conventional computational systems. Here we show that by considering the variation of the fractal dimension of...
