The bit permutation unit consists of bit permutation network and configuration information. In the article, a configuration information parallel extraction algorithm with time complexity O (log2N) based on Waksman network is presented to achieve not only bit permutation system on reconfigurable cipher microprocessors but also an arbitrary N × N bit permutation. This algorithm can support bit permutation...
This paper proposes a new process mapping scheme called adjacency-based mapping (AM) for irregular cluster systems assuming that the two-dimensional mesh process topology is specified as an interprocess communication pattern. The proposed AM tries to map neighboring processes in virtual process topology to adjacent processors in physical processor topology. Simulation study shows that the proposed...
This paper presents a new approach for solving network routing optimization problems. In particular, the goal is to optimize the traffic in the network structured event-driven systems as well as to provide means for efficient adaptation of the system to changes in the environment-i.e. when some nodes and/or links fail. Many network routing optimization problems belong to the class of NP hard problems,...
Most network operators have considered reducing Label Switched Routers (LSR) label spaces (i.e. the number of labels that can be used) as a means of simplifying management of underlaying Virtual Private Networks (VPNs) and, hence, reducing operational expenditure (OPEX). This letter discusses the problem of reducing the label spaces in Multiprotocol Label Switched (MPLS) networks using label merging...
