Full-chip power ground electro-migration assessment requires a power map, thermal map and checks for IR drops exceeding the design specifications. This paper provides a survey of the three main computation operations required to get these information.
A latency-hiding algorithm for the parallelization of large scale agent-based model simulations (ABMS) on parallel/distributed computing platform is proposed. The key idea of this algorithm is using redundant computations to hide communication latencies. An analytical model for this algorithm is presented to tell how to select R value to reach the best speedup. Compared to B+2R algorithm [1], theoretical...
As a typical complex embedded computer control system, computer numerical control(CNC) system development is confronted with a great challenge because of its specific requirements as well as some recent development trends such as ever more complex products while at lower prices and shorter develop cycle. In this paper, a model driven methodology for CNC system design and development is presented,...
Given a video sequence about the road scenarios, discovering the foreground objects and labeling them are crucial. This paper proposes to represent the foreground objects in videos by the bag of words model. The foreground object is treated as a positive document which is a set oi image patches, and the background region is a negative document. Initially the training image patches are sampled and...
A component-based model integration approach for the embedded computer control system (ECS) development is proposed in this paper. The three-layer architecture for modeling, verification as well as implementation is described. Model strategies such as multi-aspect & multi-view description method, DSML (domain specific modeling language) & FML(formal modeling language) description method as...
With the rapid development of network scale, the current SNMP network management model has not been able to meet requirements. Therefore, a new kind of management system and strategy must be provided to enhance the reliability and performance of the network management. This article discusses problems existed in traditional network and analyses the management system structure and management mechanism...
Active network is a new framework where it not only forwards packets, but also performs customized computation on packets. It provides a programmable interface to users where users dynamically inject services through nodes. This paper discusses the forwarding model and mechanism of message based on active network management model, analyzes the structure and characteristics of this model, and studies...
