NettetD4.2.1 About the VMSAv8-64 address translation system. 中文版. The Memory Management Unit (MMU) controls address translation, memory access permissions, and memory attribute determination and checking, for memory accesses made by the PE. NettetHere you can see that that the MMU address translation function implements virtual memory, so programs can use the full address range. In addition, multiple programs may have the same logical address range simultaneously, and the MMU uses dynamic management of RAM. The MMU protection function protects supervisor areas from …
