Based On The Embedded Platform Multimedia Data Processing Middleware Technology

Initially, mobile phones, personal digital assistant (PDA), audio player, video player and other products are independent of each other. With the decrease of software and hardware technology mature and the cost, more and more people have the ability to have several of these products. Therefore, the original embedded function independent computing devices, the current trend in the development of each other, the different functions of the device on the same device. Among them, the application of multimedia related will also play an important role.This paper will calculate the characteristics of equipment by analyzing the embedded multimedia applications, requirement analysis of multimedia data processing subsystem is given, on the basis of the multimedia data processing subsystem design, and focuses on the design and implementation of the system resources and packaging system functional aspects of the system. Multimedia data processing subsystem adopts the form of middleware. It is through the organization of system resources, package operating systemThe processing design basis function three layer system structure in the layer of the multimedia data is explained. Basic function layer to achieve operating system functions, function calls for multimedia data processing subsystem layer provides interprocess communication, clock, cache and data flow mechanism. This paper described in detail in the final design of data processing flow mechanism subsystem for multimedia data. In the multimedia data processing by data stream and sending data to obtain. Gets the data from the stream flow data and sending data to the data including the synchronous and asynchronous. This paper also separately to these two kinds of data acquisition and transmission processes are described.
