To avoid data corruption, error correction codes (ECCs) are widely used to protect memories. ECCs introduce a delay penalty in accessing the data as encoding or decoding has to be performed. This limits the use of ECCs in high-speed memories. This has led to the use of simple codes such as single error correction double error detection (SEC-DED) codes. However, as technology scales multiple cell upsets...
Computing the encoding delay and bandwidth on the nodes is important for the deployment and implementation of network coding. However, the existing researches merely use the methods of experimental measurement or rough estimation to investigate it. In order to accurately compute the delay and bandwidth on the nodes with network coding implemented, this paper proposes a novel method to quantify encoding...
In the context of networks providing QoS guarantees, the end-to-end delay experienced by a packet is an important parameter. In this paper, we show that network coding can be used to decrease worst case end-to-end bounds when compared to a classical routing strategy. This result can be explained by the fact that network coding can cope with congestion better that classical routing due to its property...
In this paper a novel interpretation of encoding and decoding of recursive convolutional codes is presented. By means of Galois field arithmetic a code is separated into sub-codes with a single delay operator. One of these simple sub-codes is sufficient for encoding and decoding with the equivalent trellis diagram. This paper is not targeted at performance improvements but a new insights for the analysis...
