摘要
VxWorks操作系统提供文件系统来访问和管理Flash存储器,这种方式不能满足实时写入和系统可控的要求。本文提出一种通过接管系统时钟中断来控制FlashMemory读写操作和基于管理区的简单可控文件管理方案,实现移动通信系统在不影响业务模块运行的前提下,满足对实时性和可控性要求。
VxWorks OS offers file system to access and manage FLASH Memory. But this mode can＇t meet specified requirements such as real time access and controllability. In this paper, a new method is proposed to solve these problems. The novel feature is using system clock interrupt handler to operate Flash Memory, and using memory management area to implement a simple and controllable file management function. This solution can achieve its goals of real time access and controllability without influence on the system traffic module.
