Adaptive Receiver Design for High Speed Optical Communication

Conventional input/output (IO) links consume power, independent of changes in the bandwidth demand by the system they are deployed in. As the system is designed to satisfy the peak bandwidth demand, most of the time the IO links are idle but still consumin ...

Reliability Analysis of Data Storage Systems

Vinodh Venkatesan

Modern data storage systems are extremely large and consist of several tens or hundreds of nodes. In such systems, node failures are daily events, and safeguarding data from them poses a serious design challenge. The focus of this thesis is on the data rel ...

Reliability of clustered vs. declustered replica placement in data storage systems

Rüdiger Urbanke, Christina Fragouli

The placement of replicas across storage nodes in a replication-based storage system is known to affect rebuild times and therefore system reliability. Earlier work has shown that, for a replication factor of two, the reliability is essentially unaffected ...

Effect of replica placement on the reliability of large scale data storage systems

Christina Fragouli, Vinodh Venkatesan, Xiao-Yu Hu, Robert Haas

Replication is a widely used method to protect large- scale data storage systems from data loss when storage nodes fail. It is well known that the placement of replicas of the different data blocks across the nodes affects the time to rebuild. Several syst ...

The complexity of reliable distributed storage

Ron Levy

Distributed storage systems based on commodity hardware have gained in popularity because they are cheaper, can be made more reliable and offer better scalability than centralized storage systems. However, implementing and managing such systems is more com ...

A Power-Efficient Clock and Data Recovery Circuit in 0.18-um CMOS Technology for Multi-Channel Short-Haul Optical Data Communication

Seyed Armin Tajalli, Paul Victor Georges Muller, Yusuf Leblebici

This paper studies the specifications of gated-oscillator-based clock and data recovery circuits (GO CDRs) designed for short haul optical data communication systems. Jitter tolerance (JTOL) and frequency tolerance (FTOL) are analyzed and modeled as two ma ...

Design and Integration of All-Silicon Fiber-Optic Receivers for Multi-Gigabit Chip-to-Chip Links

Seyed Armin Tajalli, Paul Victor Georges Muller, Yusuf Leblebici

This paper presents a top-down approach to the design of all-silicon CMOS-based fully integrated optical receivers. From the system-level requirements, we determine the optimum block-level specifications, based on which the individual building blocks are d ...

A standard CMOS multi-channel single-chip receiver for multi-gigabit optical data communications

Paul Victor Georges Muller

As dictated by ongoing technology scaling and the advent of multi-core systems, each new generation of microprocessors and digital signal processors provides higher computing power and data throughput. However, the available bandwidth of the input/output ( ...

Jitter Tolerance Analysis of Clock and Data Recovery Circuits using Matlab and VHDL-AMS

Paul Victor Georges Muller, Yusuf Leblebici

In the scope of the development of a complete top-down design flow targeting clock and data recovery circuits for high-speed data links, we present two methods to analyze the jitter tolerance of such links, based on statistical simulation of incoming data ...
