Abstract
- Maintains mappings between Memory Page and the Memory Frames. The mappings are stored inside the Main Memory, we can use Translation Lookaside Buffer to reduce the number of memory access since memory access is an expensive operation
Attention
Each Process (进程) has its own Page Table for better memory protection.
Page Table Mapping
- The above diagram assumes the Memory Page and the Memory Frames are
4kb. The Translation Lookaside Buffer is part of Memory Management Unit (MMU) that handles the mapping - As you can see, the value in the mapping ignores the last 12 Bit which is known as the page offset. The same memory page number share the same memory frame number
