Small aircraft often used RS485 bus. But with the complexity of the small aircraft's subsystems increase and the progress of field bus technology CAN bus systems in small aircraft use more and more widely. How to record real-time flight experiment data on the small aircraft's CAN bus and provide test data for reproducing the process of a small aircraft flying is very important.

In view of the current stringent need to the real-time compression algorithm of the high-speed and high-resolution image such as remote sensing or medical image and so on in this paper No List SPIHT (NLS) algorithm has been improved and a fast parallel SPIHT algorithm is proposed which is suitable to implement with FPGA. It can deal with all bit-planes simultaneously and process in the speed of 4pixels/period so the encoding time is only relative to the image resolution. The experimental results show that the processing capacity can achieve 200MPixels/s when the input clock is 50MHz the system of this paper need 2.29ms to complete lossless compression of a 512x512x8bit image and only requires 1.31ms in the optimal state. The improved algorithm keeps the high SNR unchanged increases the speed greatly and reduces the size of the needed storage space. It can implement lossless or lossy compression and the compression ratio can be controlled. It could be widely used in the field of the high-speed and high-resolution image compression. 2010 IEEE.

The main constrained problem of the video monitoring and storage system is the contradiction between large field of view and storage space limitations. Not all of the video information introduced by the image sensors need to be recorded especially for some tracking system which has appointed functions to track specifically kinds of targets. For instance the system not only works for single target if the monitor is appointed for human face tracking but also can work for multi-targets. High reconstruction resolution in the fovea region enables the successive application of recognition modules without sacrificing their performance the best system appears to be concentrating on human face only and all the others considered being background the low reconstruction resolution in the periphery helps to reduce the video data. 2010 IEEE. the background regions needn't to be recorded in detail. For this purpose this letter presents a real-time foveate storage system which efficiently represents the video image in log-polar coordinates with the foveate point centered on the target

A special Controller Area Network (CAN) bus application layer protocol is designed for the highly reliable communication of microcomputer-based systems in aerocraft control system by analyzing the practical time sequence of data transmission data priority data type and data function etc in this paper. Identifier distribution data storage form data type data exchange method and fault handling mechanism of the application layer protocol are specified in detail in the background of a real aerocraft control system. At last a simulation platform based on CAN bus for aerocraft control system is built to validate the design. Experimental results show that this application layer protocol meets the requirements of data transmission reliability real-time and high efficiency. The bus load rate is low and there is great room for expansion. 2010 IEEE.

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 is storied into the NandFlash array. To improve the record speed and extend record capacity the pipelining and parallel bus mechanism is adopted. The experiment which is based on hardware platform indicates the camera can take about 250f/s at a resolution of 640*480 the consistent storage speed is up to 614.4 Mb/s consistent transmit from flash to Camera Link speed up to 1.093Gb/s.The system record time is up to 18.6 minutes. 2009 IEEE.

In domains of aerospace aviation aiming and optic measure etc. the embedded system of imaging processing and recording is absolutely necessary which has small volume high processing speed and high resolution. But the embedded storage technology becomes system bottleneck because of developing slowly. It is used to use RAID to promote storage speed but it is unsuitable for the embedded system because of its big volume. Fiber channel (FC) technology offers a new method to develop the high-speed portable storage system. In order to make storage subsystem meet the needs of high storage rate make use of powerful Virtex-4 FPGA and high speed fiber channel advance a project of embedded system of digital image storage based on Xilinx Fiber Channel Arbitrated Loop LogiCORE. This project utilizes Virtex4 RocketIO MGT transceivers to transmit the data serially and connects many Fiber Channel hard drivers by using of Arbitrated Loop optionally. It can achieve 400MBps storage rate breaks through the bottleneck of PCI interface and has excellences of high-speed real-time portable and massive capacity.
