The scale of data used in graph analytics grows at an unprecedented rate. More than ever, domain experts require efficient and parallel algorithms for tasks in graph analytics. One such task is the truss decomposition, which is a hierarchical decomposition of the edges of a graph and is closely related to the task of triangle enumeration. As evidenced by the recent GraphChallenge, existing algorithms...
Polar codes have become increasingly popular recently because of their capacity achieving property. In this paper, a memory efficient stage-combined belief propagation (BP) decoder design for polar codes is presented. Firstly, we briefly reviewed the conventional BP decoding algorithm. Then a stage-combined BP decoding algorithm which combines two adjacent stages into one stage and the corresponding...
Graph analytics are arguably one of the most demanding workloads for high-performance systems and interconnection networks. Graph applications often display all-to-all, fine-grained, high-rate communication patterns that expose the limits of the network protocol stacks. Load and communication imbalance generate hard-to-predict network hot-spots, and may require computational steering due to unpredictable...
Wireless Sensor Networks (WSNs) have played an important role in diverse domains. However, programming on WSN nodes are quite hard because currently there exist no standard software and hardware platforms in WSN. Thus it's essential to build a software infrastructure that can provide a decent development environment to the users. One sound choice to achieve this objective is to deploy embedded Java...
Wireless Sensor Network 'WSN' is an active research field which explores many technological challenges, while the WSN node design is one of the most challenging areas. Nowadays, many wireless sensor nodes are implemented such as BTnodes, l'ESB/2 nodes, SmartTags, EYES node, TinyNode, Mote, Mica2, Tmote Sky, Atlas and Imote. Note that, all these wireless sensor nodes are quite similar in term of functionality...
Hardware Software partitioning is one of the most significant part of Hardware Software co-design of embedded systems, which is directly related to performance and cost. A lot of works have been done such as the simulated annealing algorithm, greedy algorithm and evaluation algorithm. In this paper, a new hardware software partitioning method based on Immune Algorithm was introduced. The model of...
