Abstract: 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.
