Software reliability analysis is a significant measure to guide design of software reliability. Now software fault tree method to carry on software reliability analysis is used more and more. But it can only qualitative carry on the analysis because of many reasons. For example
the scale of software is enlarging
the software architecture is getting more and more complex
the reason of software fault is very difficult to analyze
the software is difference with hardware
and it is very hard to obtain the expiration the quantitative data and so on. The space camera is extremely high to the reliable request. So the qualitative analysis is unable to satisfy the analysis request. In view of space camera characteristics
a method of fault tree analysis based on fuzzy synthetic evaluation is proposed. The results show that the new method makes software quantitative fault tree analysis possible and optimizes. It can also solve the problem of software component which is unable to quantize precisely. 2011 IEEE.

Control and management of the urban traffic signal is an problem that modern city has to face. The traffic signal controller makes a great contribution to the improvement of traffic status and the reduction of traffic jam. A traffic controller is designed using the technology of USB host based on ISP1161A. Universal serial bus is new interface bus architecture for PC
which supports the PnP function Of PC peripheral equipments and has been widely used in computer and communicational devices. ISP1161A complies with the protocol of USB1.1
and is used as the core part of the system. As a new try
the USB host technology is applied into the design of controller to implement the communication with PC. Configuration of scheme is carried out successfully. The USB host technology makes configuration of scheme and future update easier and more convenient. 2011 IEEE.

To improve the image processing system of resolution capability and reliability
image processing system in a growing number of multi-sensor model. In this mode
the use of the current main stream single DSP + FPGA hardware architecture for image processing algorithms have already unable to meet the operational requirements of real-time. This paper proposed a new hardware architecture that is the three DSPs based on FPGA. With the traditional master-slave architectures is different
three DSP's external interfaces are connected with FPGA and other peripheral interfaces are connected to the FPGA. In the architecture
DSP is in the same position three and FPGA flow control for data management and other function to achieve. This connection has a strong restructuring and expansion
software development and more flexible. 2011 IEEE.

Currently most existing remote controls for consumer electronics use infrared remotes (IR) technology to control devices which Increases the demand for advanced functionality that cannot be supported by existing IR. RF remotes provide new levels of interactivity and convenience for today's digital home when compared to IR remotes. New network protocols: ZigBee RF4CE are helping to make this technology accessible to us. In this paper
we first introduce the architecture and primitives of the ZigBee RF4CE
node initialization service
then present the researches of the Application layer and Network layer respectively. Focusing on the functions of Network layer including: frequency usage service
transmission control service
discovery service
power saving service
pairing service and security service. 2010 IEEE.

A new DirectShow application in the field of LED Panel display system is shown in this paper. It realizes video processing functions with DirectShow architecture on computer. Source Filter and many Transform Filters
which provided by Microsoft Co.
transform source video into RGB24 format. Then
the video data are scaled up/down to LED panel resolution by Fixformat Filter which inherite CTramsformfilter baseclass. After that
the R/G/B values of video data are adjusted in CCorrect Filter to adapt LED Panel display. Finally
the processed video is shown on LED Wall through DVI or VGA interface. Our experimental results demonstrate that this system makes a good performance. It is greatly simplify the functions of Sending-Board
Receiving Board
and Control-Scanning-Board in display system of the LED Wall. The total cost will be cut down observably
if we can transplant the filters into the embedded platform
to build a special video processing system for LED Panel display. 2009 IEEE.

Star sensor is a special high accuracy photoelectric sensor. Attitude acquisition time is an important function index of star sensor. In this paper
the design target is to acquire 10 samples per second dynamic performance. On the basis of analyzing CCD signals timing and star image processing
a new design and a special parallel architecture for improving star image processing are presented in this paper. In the design
the operation moving the data in expanded windows including the star to the on-chip memory of DSP is arranged in the invalid period of CCD frame signal. During the CCD saving the star image to memory
DSP processes the data in the on-chip memory. This parallelism greatly improves the efficiency of processing. The scheme proposed here results in enormous savings of memory normally required. In the scheme
DSP HOLD mode and CPLD technology are used to make a shared memory between CCD and DSP. The efficiency of processing is discussed in numerical tests. Only in 3.5ms is acquired the five lightest stars in the star acquisition stage. In 43us
the data in five expanded windows including stars are moved into the internal memory of DSP
and in 1.6ms
five star coordinates are achieved in the star tracking stage.
