嵌入式WinCE多线程编程研究与实现

Embedded WinCE Research and Implementation of multi-threaded programming

Windows ce 5.0作为一个多任务操作系统,采用了一种新的任务调度机制。原理上它将一个进程划分为多个线程,每个线程按照一定的调度策略占用CPU的运行时间及其资源,这样使得CPU的调度单元很小,从而提高了CPU并发处理能力。本文以线程的创建,线程功能的实现,最后将2个线程在wince 5.0上并发运行,达到了理论和实践的结合,更进一步了解了线程在嵌入式Windows

Windows ce 5.0 as a multi-tasking operating system,using a new task scheduling mechanism. In principle it a process is divided into multiple threads,each thread according to certain scheduling policy,CPU running time and its resources,which makes CPU scheduling unit is very small,thereby increasing CPU concurrent processing capabilities. In this paper,thread creation,thread function implementation,and finally two threads run concurrently on wince 5.0,reaching a combination ol theory and practice, to further understand the threading in the embedded Windows ce in the scheduling mechanism
