Memory Hierarchy
Address Binding
Converting symbolic addresses to physical addresses:
- Compile Time: Absolute code (MS-DOS .COM)
- Load Time: Relocatable code
- Execution Time: Dynamic binding (most common)
Logical vs Physical Address
| Logical (Virtual) | Physical |
|---|---|
| Generated by CPU | Address in memory |
| Process view | Hardware view |
| 0 to max | Actual location |
MMU (Memory Management Unit) translates logical → physical
