嵌入式图像采集传输系统的多进程控制

Multi-process control used in an embedded image capture and transmission system

为解决嵌入式uClinux构成的图像采集传输系统存在的速度不匹配和资源共享问题,采用多进程算法和访问状态标志控制进程。实现了图像采集进程和文件传输进程的核心算法,建立了多进程。使用访问状态标志控制进程同步,解决了资源的竞争和共享。应用结果达到了多进程速度的匹配和资源共享。

In order to solve the velocity match and resource sharing in an image capture and transmission system under the embedded uClinux application system, the multi-process algorithm and visiting sign for control are used. The key algorithm of image collection and file transmission is implemented, thus setting up the multiprocess. The access signs are used to solve the resource competition and sharing. The application result shows that the multi-process algorithm and visiting sign can match velocity and the resource can be shared.
