    A Low-Swing Crossbar and Link Generator for Low-Power Networks-on-Chip

    Network-on-Chips (NoCs) are emerging as the answer to non-scalable buses for connecting multiple cores in Chip Multi-Processors (CMPs), and multiple IP blocks in Multi-Processor System-on-Chips (MPSoCs). These networks require an extremely low-power datapath to ensure sustained scalability, and higher performance/watt. Crossbars and links form the core of a network datapath,...

    CPHASH: A Cache-Partitioned Hash Table

    CPHASH is a concurrent hash table for multicore processors. CPHASH partitions its table across the caches of cores and uses message passing to transfer lookups/inserts to a partition. CPHASH's message passing avoids the need for locks, pipelines batches of asynchronous messages, and packs multiple messages into a single cache line...

    Polynomial Length MDS Codes With Optimal Repair in Distributed Storage

    Erasure coding is a fundamental technique to build redundancy in distributed storage systems. In classical literature in coding theory, erasure codes have been developed so that they provide the maximum tolerance to disk failure (erasures) for a given storage overhead. In particular, it is well known that Maximum Distance Separable...

    Whether and Where to Code in the Wireless Relay Channel

    The throughput benefits of random linear network codes have been studied extensively for wire-lined and wireless erasure networks. It is often assumed that all nodes within a network perform coding operations, for minimal centralized control while maximizing the throughput. In energy-constrained systems, however, coding sub-graphs should be chosen to minimize...
