The invention discloses a TMS320C6747-based task context switchover optimization method. The method comprises the steps that registers needing to be stored for task context switchover are screened, and normal running of an operating system is guaranteed through least registers; the parallel execution degree of task context switchover codes is increased through a TMS320C6747 hardware assembly line; the number of memory accesses is reduced through a double-word instruction, and code execution efficiency is improved. After the method is adopted for optimizing the task context switchover codes of the embedded real-time operating system based on a TMS320C6747 hardware platform, task switchover time of the operating system is obviously shortened, so that the real time performance of the operating system is improved, and the method can satisfy occasions with a high requirement for real time performance.
