摘　　要：本文详细介绍μC/OS在TMS320C6711DSP上的移植过程,即数据类型转化为编译器能编译的数据类型、设计μC/OS与DSP硬件的接口、设计硬件抽象层函数。另外利用CPU及其指令系统特点,通过设计2个堆栈指针寄存器和任务帧,设计可并行堆栈,并提出“双通道并行入/出栈法”,同时,讨论了移植代码的优化。A transplant process of μC/OS on Texas Instruments Corporation＇s TMS320C6711 is discussed in detail, therefore, data type has been defined by the compiler and the μC/OS interface of DSP hardware and has been designed and hardware abstract level is implemented. Moreover, a parallelizable stack and double-channel pushing ＆ popping technique is invented by studying the architecture of the DSP CPU and defining a task frame and two stack pointers , at the same time, the optimization of transplant code for μC/OS is discussed.
