A Fault-Robust SPMD Architecture for 3D-TV
نویسندگان
چکیده
A fault-tolerant embedded SPMD architecture to support a pyramidal Quad-Tree motion/disparity estimation algorithm for stereoscopic image processing is proposed in this paper. The fault tolerance is obtained by using spares only for the image quality bottleneck modules (which are 6 on 90 modules) and by data derouting. Given the structure of the architecture that permits error confinement, the data derouting allows a graceful degradation of the image quality, progressively decaying with the number of faulty modules.

Design and Test of New Robust QCA Sequential Circuits
One of the several promising new technologies for computing at nano-scale is quantum-dot cellular automata (QCA). In this paper, new designs for different QCA sequential circuits are presented. Using an efficient QCA D flip-flop (DFF) architecture, a 5-bit counter, a novel single edge generator (SEG) and a divide-by-2 counter are implemented. Also, some types of oscillators, a new edge-t...
متن کاملA Robust Adaptive Observer-Based Time Varying Fault Estimation
This paper presents a new observer design methodology for a time varying actuator fault estimation. A new linear matrix inequality (LMI) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (FAFE). The FAFE is capable of estimating a wide range of time-varying actuator fault...

Due to the important role of the boiler-turbine units in industries and electricity generation, it is important to diagnose different types of faults in different parts of boiler-turbine system. Different parts of a boiler-turbine system like the sensor or actuator or plant can be affected by various types of faults. In this paper, the effects of the occurrence of faults on the actuators are in...
متن کاملCompiler Assisted Fault Detection for Distributed-Memory Systems
Distributed-memory systems provide the most promising performance to cost ratio for multiprocessor computers due to their scalability. However the issues of fault detection and fault tolerance are critical in such systems since the probability of having faulty components increases with the number of processors. We propose a methodology for fault detection through compiler support. More speci ca...
