Design And Realization Of Multimedia Software Framework Based On Skyworks Platform

Along with the increasing functions, the handset is transforming from "the communication facility" to "the multimedia terminal". Specially, along with 3G era approaching day by day, will highlight the strong points of handset multimedia functions. The complication of handset functions, especially the diversification of multimedia functions, will disfavor the traditional one-CPU mobile system. Therefore, more and more designers began to use two CPUs in charge of Audio/Video (codec, JPEG, MP3, MPEG4...) and connectivity (voice transmission, TV, GPS, Bluetooth, Internet...) respectively, by adding one multimedia chip to the original system. Moreover, the multimedia software frameworks must also be added to the original mobile system, so as to realize multimedia functions on top of its original functions. .The thesis first introduced the present handset multimedia development situation and the market background. With the current mobile phone technology features, Describe the significance of the topic and main task. Then, conducted the research to the Skyworks hardware platform processing chip and the multimedia chip, and produced the hardware connection plan. After that, in the research the Skyworks software platform, started the entire multimedia software framework system design. Finally, realized handset multimedia functions in the framework has been designed, and verified the feasibility of the reality of the entire multimedia software framework design.The thesis is the author based on practical projects in the field of communications, summarized the handset multimedia functions realization universal theory, then, conducted the research and the design to the handset multimedia software framework, and enabled this framework to have certain versatility.
