A Real-time Display Software Based on QML and GPU Programming

In order to achieve domestic autonomy and controllability, based on domestic CPU and Kylin operating system, a cross-platform real-time display software is designed by using qt meta language (QML) and graphics processing unit (GPU) programming mode. The software architecture design based on QML is described in detail, and the key technologies in the software design, such as the communication mode of QML, C + + and GPU, the real-time display performance optimization method of CPU + GPU programming under QML, and the design of QML display control are described in detail, and then the verification application is carried out. The application results show that the model is reliable, stable, efficient and cross-platform, and meets the requirements of real-time display applications.
