| Abstract: | To implement high efficiency and reliability of the memory access under the condition of limited memory resources of the embedded system, the memory management mechanism of the VxWorks operation system is analyzed. A light-weighted virtual memory management mechanism is introduced, in which the virtual address space is implemented by the memory mapping method and each task is provided with sufficient memory size by the swapping method. The experiment shows the availability and usability of the implementation. |
