In order to satisfy requirements of real time and parallel control for the space optical remote sensor and implement the high integration of software  a kind of VxWorks-based multitask software architecture was put forward. Firstly  the technological requirements of optical remote sensor were analyzed in detail and functions and performances of the optical remote sensor were fixed. Task that was based on each function of optical remote sensor was compartmentalized. Then  software architecture of optical remote sensor was designed. Finally  experiments were carried out and results verified the accuracy and feasibility of the software architecture. Test results showed that the software architecture satisfied the requirements of real time and parallel control for the space optical remote sensor  its functions and performances met the system design target perfectly  and the software architecture was applicable to the engineering application of space instrument. 2011 IEEE.

In order to solve the compute-intensive character of image processing  based on advantages of GPU parallel operation  parallel acceleration processing technique is proposed for image. First  efficient architecture of GPU is introduced that improves computational efficiency  comparing with CPU. Then  Sobel edge detector and homomorphic filtering  two representative image processing algorithms  are embedded into GPU to validate the technique. Finally  tested image data of different resolutions are used on CPU and GPU hardware platform to compare computational efficiency of GPU and CPU. Experimental results indicate that if data transfer time  between host memory and device memory  is taken into account  speed of the two algorithms implemented on GPU can be improved approximately 25 times and 49 times as fast as CPU  respectively  and GPU is practical for image processing. 2010 IEEE.

With growing system complication  multiple structures are constructed in software  instead of single architecture style. As a result  the traditional architecture-based models that have considered only homogeneous software behaviors are not suitable to the complex system. In this paper a heterogeneous architecture-based model is presented. In order to verify the practicability  we apply the model to estimate the system reliability of the astronautics payload communication and monitoring system (APCMS). Multiple structures are constructed in the system  i.e.  sequence  parallel and fault-tolerance. The study results demonstrate that the model is accurate when compared to the actual reliability. Theoretical research must be applied on actual systems to understand their applicability and accuracy. 2008 IEEE.
