| 摘 要： | 信号量是用来控制共享资源互斥访问和线程同步通信的协议机制，它是操作系统中的重要部分。基于广泛使用的高性能数字信号处理器ADSP—TS201，从线程创建、调度策略和信号量操作这三个方面，设计并实现实时操作系统中的信号量机制，为下一步开发完整的实时操作系统奠定了基础。

| Abstract: | Semaphore is a protocol mechanism, which is applied in access shared resource mutually and synchronizing communication. It is an important scheme in operating system. According to thread creation, scheduling policy and semaphore operation, the paper describes the design and implementation of the semaphore mechanism of a real time operating system (RTOS), which is based on popularly used high performance digital signal processor ADSP-TS201. The mechanism lays a foundation for the following development of the integrated RTOS. |
