FASA (Future Automation System Architecture) is a scalable, flexible, and platform-independent real-time execution framework for executing cyclic applications on multiple CPU cores or even across multiple devices. By design, FASA does not support event-driven tasks, such as handling of I/O and network communication. However, providing support for event handling is vital to broaden FASA's applicability...
The analysis of data streams is of great value in many fields such as network monitoring and sensor instrumentation. As a common operation, top-k query over data stream is the basis and core of other problems in data stream analysis. In this paper, we introduce a parallel algorithm based on Frequent algorithm and implement it by utilizing Apache Storm. Further, we evaluate the algorithm by estimated...
This paper presents a three-dimensional (3D) die-level integration platform, MorPACK. The structure of MorPACK is 3D stacked by the connection modules and circuit modules. It makes MorPACK platform own heterogeneous integration capabilities. With proper system partition and tri-state interface connection, the MorPACK system can be extended by the peripheral interfaces efficiently and alternate the...
This paper describes an Open Flow-based prototype of a SDN-oriented stateful hardware firewall. The prototype of a SDN-oriented stateful hardware firewall includes an Open Flow-enabled switch and a firewall controller. The security rules are specified in the flow table in both the Open Flow-enabled switch and the firewall controller. The firewall controller is in charge of making control decisions...
This paper describes a vision based on dedicated CDMA 1X wireless data terminal, applies the embedded development technologies, designs of the hardware interfaces and software and implements a wireless data terminal based on CDMA 1X, according to the functional requirements for wireless broadband communication systems.
Most existing research in disk power management has focused on exploiting idle periods of disks. Both hardware power-saving mechanisms (such as spin-down disks and multi-speed disks) and complementary software strategies (such as code and data layout transformations to increase the length of idle periods) have been explored. However, while hardware power-saving mechanisms cannot handle short idle...
Partial Reconfiguration (PR) is an FPGA feature that allows the modification of certain parts of an FPGA while the rest of it continues to operate without disruption. This distinctive characteristic of FPGAs has many potential benefits but also challenges. The lack of good CAD tools and the deep hardware knowledge requirement result in a hard to use feature. In this paper, the new Partition-based...
Java is one of the most popular programming architectures because of its platform-independence. Its platform-independence depends on Java virtual machine JVM. Compared to executing class file on hardware JVM, executing class file on software JVM is much slower. By studying we master the component architecture and the working principle of software JVM based on the class file to explain the implementation...
According the specialty of wireless sensor network technology and the characteristic of warehouse measure and control system, an intelligent warehouse measure and control system based on Zigbee WSN and network nodes are designed. At the same time, the whole design frame and the hardware structure of sensor nodes and applications software flow chart are analyzed. The Zigbee wireless sensor network...

ARM9 microprocessor is selected as a remote controller, a rotary encoder is used for providing with car's position and initial speed information. The design, which uses GPRS technology to accomplish wireless data transport...
With the increase of the non-liner power loads and impact loads in power systems, the pollution of power quality is becoming more serious. It is important to put up multi-dimensional monitoring and construct monitoring network. In this paper the hardware and software scheme of a new power quality monitoring terminal based on configuration software is introduced in detail, which is applied to different...
The development of modern embedded system needs more practical design technology with larger covering scope. A codesign method called DT (Dual-Trees) is proposed for system-level in coarse-grained view. This method builds behavior-tree and resource-tree by UML description and achieves the reasonable design results through analyzing the two trees integrally. Compared with other codesign methods, DT...
