TAILIEUCHUNG - Lecture Operating system concepts (Fifth edition): Module 8 - Avi Silberschatz, Peter Galvin

Module 8 - Memory management. After completing this unit, you should be able to: Explain the difference between logical and physical addresses, explain the difference between internal and external fragmentation, explain the following allocation algorithms. | Module 8: Memory Management Background Logical versus Physical Address Space Swapping Contiguous Allocation Paging Segmentation Segmentation with Paging Operating System Concepts Background Program must be brought into memory and placed within a process for it to be executed. Input queue – collection of processes on the disk that are waiting to be brought into memory for execution. User programs go through several steps before being executed. Operating System Concepts Binding of Instructions and Data to Memory Compile time: If memory location known a priori, absolute code can be generated; must recompile code if starting location changes. Load time: Must generate relocatable code if memory location is not known at compile time. Execution time: Binding delayed until run time if the process can be moved during its execution from one memory segment to another. Need hardware support for address maps (., base and limit registers). Address binding of instructions and data to memory .
