This, paper presents a novel approach towards a comprehensive analysis of various simulation-based tools to test and measure the Cloud Datacenter performance, scalability, robustness and complexity. There are different Cloud Datacenter resources in cloud Computing Infrastructure like Virtual Machine, CPU, RAM, SAN, LAN and WAN topologies. The server machines need to be analyzed for their extent of...
Technology scaling advancement coupled with operational and environmental effects make embedded memories more vulnerable to both manufacturing and transient errors including multi-bit upsets. Conventional error correcting codes incur high latency, area, and power overheads to correct multi-bit errors. In this paper, we propose Embedded Erasure Coding (EEC), a low-cost technique that can correct multi-bit...
Non-Binary LDPC codes are nowadays considered as a potential competitor of both binary LDPC and convolutional Turbo Codes, mainly when codes with short and moderate codeword lengths are used. The decoding process of these codes suffers from a high computational complexity which necessitates a high memory requirements to store the intrinsic and extrinsic Likelihood Ratio (LLR) messages. This paper...
When the code is not long, non-binary low-density parity-check (NB-LDPC) codes can achieve better error-correcting performance than binary LDPC codes at the cost of higher decoding complexity. The recently developed iterative reliability-based majority-logic NB-LDPC decoding can achieve better performance-complexity tradeoffs than previous algorithms. Many existing NB-LDPC code construction schemes...
This paper presents principles and results of dynamic testing of an SRAM-based FPGA using time- resolved fault injection with a pulsed laser. The synchronization setup and experimental procedure are detailed. Fault injection results obtained with a DES crypto-core application implemented on a Xilinx Virtex II are discussed.
Timing-error detection and recovery circuits are implemented in a 65 nm resilient circuit test-chip to eliminate the clock frequency guardband from dynamic supply voltage (VCC) and temperature variations as well as to exploit path-activation probabilities for maximizing throughput. Two error-detection sequential (EDS) circuits are introduced to preserve the timing-error detection capability of previous...
Continuous scaling, necessary for enhanced performance and cost reduction, has pushed existing CMOS materials much closer to their intrinsic reliability limits, forcing reliability engineers to get a better understanding of circuit failure. This requires that designers will have to be very careful with phenomena such as high current densities or voltage overshoots. In addition to the reliability issues,...
Novel 3D stacked gate-all-around multichannel CMOS architectures were developed to propose low leakage solutions and new design opportunities for sub-32 nm nodes. Those architectures offer specific advantages compared to other planar or non planar CMOS devices. In particular, ultra-low IOFF (< 20 pA/mum) and high ION (> 2.2 mA/mum) were demonstrated. Moreover, those transistors do not suffer...
3D contactless technology based on capacitive coupling represents a promising solution for high-speed and low power signaling in vertically integrated chips. AC coupled interconnects do not suffer from mechanical stress, and the parasitic load is much reduced when compared to standard DC solutions, such as wire bonding and micro bumps. Communication system based on wireless interconnection scheme...
This paper describes a methodology for building a reliable internet core router that considers the vulnerability of its electronic components to single event upset (SEU). It begins with a set of meaningful system level metrics that can be related to product reliability requirements. A specification is then defined that can be effectively used during the system architecture, silicon and software design...
