Due to the expensive hardware and complex management of the traditional middlebox, a concerted effort towards the virtualized middlebox has been launched in both academia and industry. In this paper, we propose a unified middlebox model, MBBrick, which is composed of three operation modules (classifier, rewriter, forwarder) and a control module (the mcontroller). We then design a language, MG, to...
A component based hybrid embedded framework for mobile robot is presented in this paper. There are 3 layers in this framework, data layer, real-time layer, and high performance layer. The hardware consists of a hybrid architecture of Advanced RISC Machine (ARM) architecture micro controller and Field Programmable Gate Array (FPGA) with high-speed parallel/serial bus. The software mainly includes a...
When the color linear array CCD camera works, the output color image has the dislocation phenomenon which has seriously affected the human visual effect. At the same time the dislocation phenomenon has also brought great trouble to the image processing. In order to resolve this problem, a real-time collection system with the PCI interface has been developed. The system not only has the image collection...
State-of-the-art hardware based techniques achieve high performance and maximize efficiency of packet classification applications. The predominant example of these, ternary content addressable memory (TCAM) based packet classification systems can achieve much higher throughput than software-based techniques. However, they suffer from high power consumption due to the highly parallel architecture and...
A configurable, record capacity extensible and nonuniformity reducible of high speed camera is designed in this paper. The CMOS image sensor lupa-300 which is produced by Cypress Corporation is used for the system. There is nonuniformity existed in the sensor. The two point method of the image with real time correction algorithm has applied to process the image nonuniformity. Then the corrected image...
