It tells the gridshell script to turn on inter-task communication using the redirect operators 它告诉gridshell脚本使用重定向操作符
Perform parallel-type execution with scripts using built-in inter-task communication and synchronization primitives 利用使用内置任务间通信和同步原语的脚本进行并行执行。
Taking can-bus driving as a instance and using embedded microprocessor's hardware character, we provide the managing mode of multi-task communication . semaphore, mailbox and message queue is used in this paper to realize the communications mechanism of multi-task 利用嵌入式微处理器的硬件特点,以can总线驱动为例,提供系统调用多任务通信管理方式,并使用基于信号量、邮箱、消息队列的通信机制进行多任务间的通信。
The paper descibes a few key techniques of the embedded software design that based on the embedded operating system . embedded operating system is the soul of the embedded system, its function is to schedule, manage and control tasks, manage the inter-task communication, task synchronization and mutex, manage system resources . the embedded operating system is not suitable for common use because of the specific application of embedded system, and it has characters of itself 嵌入式操作系统是嵌入式应用系统的灵魂,它担负着任务调度、任务控制、任务间通信与同步、资源管理、存储管理等重要任务,但嵌入式应用系统的专用性决定了嵌入式操作系统的通用性是非常低的,为了片面追求其通用性,结果往往是嵌入式操作系统的性能不能满足应用的需要。
In chapter 2, some key concepts related with c / os-ii kernel is described in details, such as task states and state-transition, task management and scheduling, time management, inter-task communication and synchronization, interrupt and clock tick . the cons and pros of c / os-ii are also listed . and a new strategy is proposed to improve the task-scheduling 第二章对c/os-ii内核进行分析,详细解释任务状态及转换、任务管理及调度、时间管理、任务间通信与同步以及中断与时钟节拍等原理,分析了c/os-ii实时内核的优缺点,并提出了c/os-ii的任务调度策略的改进方法。
