This is used by some of the architecture-dependent semaphore functions in the kernel.

这被内核中一些依赖于架构的信号量函数使用。

Mutexes are available in the kernel as a way to accomplish semaphore behavior.

在内核中可以使用互斥锁来实现信号量行为。

Introduce the kernel, memory management and partition, allocation strategy, multi-task scheduling and how to communicate by semaphore and message handling as well as interrupt management.

介绍了该操作系统的内核、存储器管理和分区、分配策略、多任务调度及任务间通过信号量和消息处理进行通信的机制、中断管理等。
