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.

Aircraft simulation platform is the most important supporting technology in the aircraft development process. This simulation platform can be used for validating the design of subsystem and also it provides the necessary data for the Aircraft design. Wind has great impact on the flight parameter. In order to accurately simulate the wind model and calculate the flight parameters  a simulation modeling method for flight parameter simulation platform under wind field environment is established. Firstly  the various sub-systems which affecting flight parameters are analyzed  some mathematical models of the flight parameter simulation platform is established. Secondly  the atmospheric wind field is studied to analyze the impact on its trajectory. Then the model is built in the Simulink toolbox in the Matlab which is based on the principles of hierarchy and modularity  using C MEX S-function for the complex kinetic equations. Finally  when the models have been established  encapsulating models for several subsystem and assembling them for the Aircraft simulation platform based on the unified interface. The simulation tests (including the performance test of a certain gliding Aircraft  the wind influence test of a certain uncontrolled aircraft) prove the simulation capability of the platform  and its calculating step can reach 1 ms. Comparing simulation with field test data of a certain uncontrolled aircraft  it shows that the relative deviation of range is 0.47%  the relative deviation of maximal altitude is 2.1%. Taking relevant standards as a reference standard  it is demonstrated the platform is reliable  meets the engineering accuracy requirements. 2010 IEEE.
