Method and system for efficient audio scheduling for dual-decode digital signal processor (DSP)

摘要

Methods and systems for coordinating the handling of information are disclosed herein and may include scheduling multiple processing tasks for processing multimedia data by a processor. A portion of the scheduled multiple processing tasks may be preprocessed and the preprocessed portion may be buffered within a modifiable buffer that handles overflow and underflow. A portion of the buffered preprocessed portion of the scheduled multiple processing tasks may be executed. The scheduling may utilize a non-preemptive scheduling algorithm, such as an earliest deadline first (EDF) scheduling algorithm and/or a rate monotonic (RM) scheduling algorithm. The scheduled multiple processing tasks may include at least one maximum real deadline. The preprocessed portion of the scheduled multiple processing tasks may be outputted during processing of the blocking task, if a current task of the scheduled multiple processing tasks comprises a blocking task.
