A New Design of Fault Tolerant Comparator
In this paper we have presented a new design of fault tolerant comparator with a fault free hot spare. The aim of this design is to achieve a low overhead of time and area in fault tolerant comparators. We have used hot standby technique to normal operation of the system without interrupting and dynamic recovery method in fault detection and correction. The circuit is divided to smaller modules...
متن کاملEvolutionary QCA Fault-Tolerant Reversible Full Adder
Today, the use of CMOS technology for the manufacture of electronic ICs has faced many limitations. Many alternatives to CMOS technology are offered and made every day. Quantum-dot cellular automata (QCA) is one of the most widely used. QCA gates and circuits have many advantages including small size, low power consumption and high speed. On the other hand, using special digital gates called re...
متن کاملTolerant Algorithms
Assume we are interested in solving a computational task, e.g., sorting n numbers, and we only have access to an unreliable primitive operation, for example, comparison between two numbers. Suppose that each primitive operation fails with probability at most p and that repeating it is not helpful, as it will result in the same outcome. Can we still approximately solve our task with probability ...
متن کاملIntrusion - Tolerant
Despite our best efforts, any sufficiently complex computer system has vulnerabilities. It is safe to assume that such vulnerabilities can be exploited by attackers who will be able to penetrate the system. Intrusion tolerance attempts to maintain acceptable service despite such intrusions. This paper presents an application of intrusiontolerance concepts to Enclaves, a software infrastructure ...
متن کاملTherapeutic drug monitoring of thiopurine metabolites in adult thiopurine tolerant IBD patients on maintenance therapy.
BACKGROUND AND AIMS Therapeutic drug monitoring of active metabolites of thiopurines, azathioprine and 6-mercaptopurine, is relatively new. The proposed therapeutic threshold level of the active 6-thioguanine nucleotides (6-TGN) is ≥235 pmol/8×10(8) erythrocytes. The aim of this prospective cross-sectional study was to compare 6-TGN levels in adult thiopurine tolerant IBD patients with an exace...
