CGRA (Coarse-Grained Reconfigurable Array) is competitive hardware architecture for streaming applications due to its excellent tradeoff between programmability and efficiency. However, the efficiency of CGRA highly depends on how applications are mapped onto it with optimized operation placement and data routing. In the routing procedure, data are transferred through different processing elements...
As we are approaching the exascale era in supercomputing, designing a balanced computer system with powerful computing ability and low energy consumption becomes increasingly important. GPU is a widely used accelerator in most recently applied supercomputers. It adopts massive multithreads to hide long latency and has high energy efficiency. In contrast to its strong computing power, GPUs have few...
To meet the demand of increasing mobile data traffic and provide better user experience, heterogeneous cellular networks (HCNs) have become a promising solution to improve both the system capacity and coverage. However, due to dense self-deployment of small cells in a limited area, serious interference from nearby base stations may occur, which results in severe performance degradation. To mitigate...
Cognitive radio technology is proposed to improve spectrum utilization efficiency through exploiting the unused portions of spectrum in an opportunistic manner. In cognitive radio networks (CRNs), primary users (PUs) are allowed to lease out their unused spectrum to share with cognitive users (CUs). In a CRN consisting of multiple PUs and CUs, the spectrum pricing and resource allocation scheme have...
Based on the developed nonlinear dynamic equations of a quadrotor (named as Qball-X4) UAV (Unmanned Aerial Vehicle), attitude and trajectory tracking control designs based on an inner/outer loop control structure has been proposed in this paper. Feedback linearization is designed to control the attitude stability in inner loop, traditional PID is designed to follow trajectory in accordance with pre-planned...
This paper has a discussion and research on building a new economics architecture for Resource management for manufacturing grid (MG) based on beneficial drive. It firstly inducts the economics roles into manufacturing gird to express the economic attributes of resources of MG. Then it analyses the relationship between different roles. And paper adopts the MGeQoS to the WSDL expression to describe...
