The Android Operating System In The Ipc Mechanism And The Analysis And Optimization Of The Media

Along with the development of computer science, the using of software is beyondthe PC domain; gradually turn to intelligent equipment, intelligent equipment have beenintegrated into the people’s production and life. People began to think about how tomake intelligent devices more intelligent, digital, thus make the intelligent equipmentconvenience, easy control, the function is complete, and efficiency is higher than before.In order to realize the new requirements that is proposed by the intelligence equipment,after the age of the PC as a core technology: embedded technology need to provideflexible and efficient software solutions. In the limited hardware resources optimizationsoftware operation efficiency is a key issue of software project that need to be resolved;This paper use characteristic of open source of Android OS platform, combining withthe demand of laboratory cooperative projects, from the analysis of the Android OS andthen when Android OS is running realizing for the purpose of optimized efficiency.In this thesis, Firstly, according to the Android OS composition and characteristicsimply introduced the basic principle, at the same time, standing in two different angleanalyses the overall framework of Android OS; Secondly, simple analysis three processcommunication mechanism of Android operating system, In-depth analyses the Bindercommunication framework and three important component: servicemanager, Binderdriver, Binder library, and the Binder communication three important process is given:registration process, the connection process, data transmission process; Thirdly,in-depth analyses Media system, understand the relationship between Media system andBinder communication framework and simple analysis the component part of Mediasystem, select Media service as a specific service; Furthermore, according to thecommunication situation of Android OS process and efficiency bottleneck puts forwarda set of practical local optimization plan, the set of the plan focuses on three aspects ofAndroid OS optimization: local optimization, parallel transmission, data tap, by the datatest, the plan basically realized the local parallelization of the communication process,in a certain extent optimization running efficiency of Android OS. Finally, based on theAndroid OS coming with simulation environment and specific goal development board with specific debugging tool realizes this set of optimization plan and tests the operationprocess, it is concluded that the optimized result.The topic is in the Android own simulator environment (Emulater) with Androiddebugging bridge (ADB) to achieve the optimization of the Binder of co mmunicationframework; Transplant the optimized file system of Android to specific developmentboard and measure a set of system operation data, by data analysis and contrast, lastlyconclude the optimization results. Basically realized parallelism effect of the processcommunication, improve the overall efficiency of the system operation.
