摘要
探讨了VxWorks中内存分配策略的实现。对80386/80486的段页式管理机制进行了介绍,对VxWorks下的内存管理机制进行了阐述,并以VxWorks下通过DMA方式传输语音数据为例进一步剖析VxWorks的内存分配策略。对于嵌入式系统和应用的开发具有一定的参考价值。
With the embedded system developing rapidly, the real-time operating system VxWorks has been widely used in embedded application. The implementation method of memory allocation is analyzed. This paper introduces segment and page memory management on 80386/80486, anatomizes the memory management mechanism on VxWorks. The DMA memory management on VxWorks is explained as an example, which is used in the transmission of the sound data.
