At present, the automated real-time embedded software testing is a hot topic. Automated testing is essentially based on user programming and how to build test script quickly and effectively is one of the key problems to be resolved. In this paper, the object-oriented and framework technologies are introduced into the real-time embedded software testing field and the real-time testing object framework (RT-TOF) is studied firstly. And then, the test script generation process based on RT-TOF is proposed. Furthermore, the design of RT-TOF is put forward. Finally, the test script sample of the avionics embedded software system testing is given. Practical application of RT-TOF in engineering shows that the method proposed in this paper can improve the efficiency of automated testing greatly and the test script based on RT-TOF has better maintainability and reusability.

Embedded software testing is a hot topic in software testing field. It is a challenge to enhance the generalization, portability, and maintainability of embedded software testing environment (ESTE). In this paper, by applying virtual machine technology into embedded software simulation testing, a custom-build embedded software simulation testing virtual machine (ESSTVM) which is composed of data type, memory management, task management, communication, testing instruction set and testing files is presented firstly. And then, ESSTVM was applied in design of avionics software testing environment (ASTE). Based on the description of architecture of ASTE, the design and implementation of the testing development system and testing execution system are put forward. Practical application of ASTE in engineering shows that the method can improve the generalization, portability, and maintainability of ESSTE effectively. Next research steps are put forward to improve the real-time capacity and efficiency of testing execution system and extend it to be distributed.

QPSK, a modulation mode with a high frequency band utilization ratio and a strong anti-noise immunity,is widely used in the field of military and satellite communication. This article based on the analysis of the traditional QPSK signal modulation and demodulation mechanism, proposes an improved QPSK signal modulation and demodulation algorithm, and have a further in-depth analysis of the feasibility of this algorithm. Finally, by MATLAB software simulation testing, simulation results shows that the algorithm can accurately generate a QPSK signal and complete a rapidly demodulation of a QPSK signal.
