PCI Express is a high-speed point-to-point transmission bus interface that widely used. but a standard PCI Express system starts to traversal the bus topology after 100ms from the power on and to make sure the equipment that ready to response the configuration request. This becomes a difficult task due to the ever-increasing configuration memory size of each new generation of FPGA, such as the Xilinx...
A miniature high-speed real-time video tracking platform which is based on the core of FPGA+DSP has been developed. The platform adopts I2C bus, link-port data transfer protocol and multi-DSP high-speed video processing. Through the combined use of DSP and FPGA, the platform has the following characteristics: high integration, strong computing power, flexible structure, good expansibility and so on,...
Embedded technology and people's lives have been closely related, but traditional data acquisition system only responds to particular signals, which is quite limited. A newly-designed idea is proposed in this paper with ARM9 processor as the core components to design a common data acquisition system. We need to use different data acquisition board according to different signals, to form a user-defined...
A novel indoor scene lighting system is presented, which is based on ARM embedded system and Zigbee wireless communication technology. It is composed of one portable controller and some node controllers. The brightness and colors of indoor LED lamps can be adjusted by the predefined scene modes or by arbitrary online control.
This paper introduces the design of hardware circuit of data acquisition system, the designed circuit of LCD (liquid crystal display) and touching screen interface is provided in detail. Through a detailed analysis of the working principle of human-computer interaction, the embedded processor S3C2410 which as the core ARM920T is produced by SAMSUNG company, which for terminal equipment and take a...
Embedded 32 bits multimedia micro-processor SPCE3200 designed by Sunplus company is used as controller and CMOS image sensor chip OV7720 is used for image acquisition by the system. The use of the eCos Configuration Tool of Embedded Configurable Operating System can configure the driver's attributes of CSI & OV7720. The camera equipment can be controlled and configured by the POSIX standard file...
Focusing on the architecture characteristics of the new computer architecture with high-security sCPU-dBUS, this paper designs and implements an inter-subsystem data transfer mechanism based on the new high-security operating system with internal networking structure netOS-I which is only used by the sCPU-dBUS. The data transfer mechanism mainly contains inter-subsystem data transfer interface, inter-subsystem...
According to the features of Direct3D graphics library and particle system, common parameters of particle system are abstracted. On the basis of them, more realistic rendering of the fountain is realized with usage of textures. Different from other algorithms, we present an algorithm in which the user can alter the fountain in real time by adjusting some parameters such as the velocity, the direction,...
