Improve system performance . Process management. Need to keep several process in memory. Share memory. Learn various techniques to manage memory. Architecture. CPU . Processing units. Caches. Interrupt controllers. MMU. Memory. Interconnect. North bridge. South bridge. PCI, . etc. PC Architecture. Address Spaces. Translation from logical to physical addresses. 1. Address . Binding. The normal procedures is to select one of the processes in the input queue and to load that process into memory.. As the process executed, it accesses instructions and data from memory, when the process terminates, and its memory space is declared available.. Main Points. Applications of memory management. What can we do with ability to trap on memory references to individual pages?. File systems and persistent storage. Goals. Abstractions. Interfaces. Address Translation Uses. Background. Virtual memory. . – separation of user logical memory from physical memory.. Only part of the program needs to be in memory for execution. Logical address space can therefore be much larger than physical address space. Chapter 7. 2. Roadmap. M. emory management . Objectives. . Requirements. Simple memory management. . Memory partitioning. . Fixed partitioning. . Dynamic partitioning. . Address translation. What is memory?. Identify four parts of the brain were memory is stored. (lecture). Hippocampus. Amygdala. Frontal Lobes/Cortex. Cerebellum. Photographic memory is also called . Eidetic memory. Confabulation. Background. Swapping . Contiguous Memory Allocation. Segmentation. Paging. Structure of the Page Table. Example: The Intel 32 and 64-bit Architectures. Example: ARM Architecture. Objectives. To provide a detailed description of various ways of organizing memory hardware. Lecture for CPSC 5155. Edward Bosworth, Ph.D.. Computer Science Department. Columbus State University. The Simple View of Memory. The simplest view of memory is . that presented . at the ISA (Instruction Set Architecture) level. At this level, memory is a . How to create a process?. On Unix systems, executable read by loader. Compiler: generates one object file per source file. Linker: combines all object files into one executable. Loader: loads executable in memory. CS550. Paging and Segmentation. . Non-contiguous memory allocation. Fragmentation is a serious problem with contiguous allocation . Non-contiguous allocation removes this problem . Modern memory systems use more advanced allocation schemes . Cued Recall. Recognition. Savings. Implicit / Indirect Memory. Procedural Memory. Declarative Memory. The Information Processing View of Memory. Short Term Memory. Long Term Memory. Episodic Memory. Source Amnesia. Without memory, experience would leave no mark on our behavior; we would be unable to retain the information and skills we acquire through experience.. What is Memory?. 3 basic processes of human memory; .
