Repair Pipelining Mechanism with Hybrid Erasure Coding for Block Chain

Repair Pipelining for Erasure-Coded Storage

We propose repair pipelining, a technique that speeds up the repair performance in general erasure-coded storage. By pipelining the repair of failed data in small-size units across storage nodes, repair pipelining reduces the repair time to approximately the same as the normal read time to the same amount of data in homogeneous environments. We further extend repair pipelining for heterogeneous...

Adaptive block transforms for hybrid video coding

A Platform-Based MPEG-4 Advanced Video Coding (AVC) Decoder with Block Level Pipelining

We present a baseline MPEG-4 AVC (Advanced Video Coding) decoder based on an optimized platform-based design methodology. With this methodology, we jointly optimize the software and hardware design of the decoder. Overall decoding throughput is increased by synchronizing the software and the dedicated co-processors. The synchronization is achieved at macroblock-level pipelining. In addition, we...

Erasure-proof coding with fusion frames

The main goal of this paper is the design of frames for transmitting vectors through a memoryless analog erasure channel. The channel transmits the frame coefficients perfectly or discards them, depending on the outcomes of Bernoulli trials with a failure probability q. For sufficiently small q, we construct frames which encode above a fixed non-zero rate and allow the receiver to recover part ...

Error-and-Erasure Decoding for Block Codes with Feedback

Shannon showed in [18] that the capacity of discrete memoryless channels (DMCs) does not increase even when a noiseless and delay free feedback link exists from receiver to transmitter. Moreover on symmetric DMCs the sphere packing bound is an upper bound for the error exponent of fixed-length block-codes, as shown by Dobrushin1 in [5]. Thus relaxations like error-and-erasure decoding or variab...
