| Abstract: | The mapping theory is presented in the thesis, which is used in the application of realizing the mapping from PCI address to Lbus address in CMTS. It also describes the theory how to access enormous Lbus memory by the limited PCI address. In the end, the thesis gives the source code in VxWorks, which is needed when the CPU tries to access the Lbus memory. |
