In this master thesis, we design and implemented a super mode for multiple streaming signal processing applications, and got the timing budget based on Senior DSP processor. This work presented great opportunity to study the real-time system and firmware design knowledge on embedded system.
With the fast development of telecommunication technologies, numbers of functions such as multi-applications or multi-connections are integrated into a modern handset or a terminal, which includes radio base band processing (download mode), voice codec, digital camera, audio mp3, video, web message, and so on. All these functions are implemented as application specific instruction set processors or ASIC modules.
Furthermore, as the most important part in a modern handset, the communication modems and play CODEC systems are real-time subsystems. So a real-time multi-task control subsystem for the DSP subsystem in a modern handset or a terminal should be put more attention as same as the other function modules.
