基于OMAP3530多媒體終端設備的軟件設計與實現(xiàn)
[Abstract]:In recent years, multimedia technology has been developed rapidly. With its strong penetration, multimedia technology has entered every aspect of human life, in the fields of game and entertainment, education and training, commerce, information, engineering simulation and service, etc. Multimedia technology is playing a more and more important role. Especially in recent years, multimedia technology is developing and improving at an unprecedented speed. The research on multimedia technology has important practical significance and high research value. In this paper, the embedded multimedia technology is combined with multimedia technology, and a multimedia playback system based on OMAP3530 multimedia terminal equipment is designed and implemented. The hardware platform of this system is OMAP3530 chip provided by TI. OMAP3530 integrates ARM Cortex A8 kernel, TMS320C64x DSP, graphics engine, video accelerator and rich multimedia peripherals. For some real time signals, such as image, video, audio data, which need a lot of computation, they can be calculated by DSP, while for communication, peripheral control and other functions, they can be realized by ARM core. Thus a good balance between power consumption and complex applications is established. In the aspect of software platform, this system adopts the open source Linux system and builds the DVSDK (Digital Video Software Development Kit) development environment on this basis. DVSDK is the Linux digital video software development suite provided by TI company. It makes it easy for developers to make use of DSP to accelerate codec without programming DSP, thus speeding up the development of multimedia applications based on Linux. Firstly, the multimedia technology and OMAP platform are studied in this paper, and the main function modules of OMAP3530EVM are also briefly introduced. Then on the basis of the hardware platform, the installation of the DVSDK development environment is completed, and the XLoade,UBoot,Kernel and Angstrom file system are cross-compiled. Then, this paper focuses on the graphical user interface framework (Qt) and the multimedia framework (GStreamer,) on the Linux system. Based on them, a multimedia player is designed and implemented. Finally, the function of the whole system is tested. The test results show that the player meets the requirements of most media and achieves the desired results.
