Virtual memory allows processes to have a logical address space that is larger than physical memory by paging portions of processes into and out of RAM as needed. When a process attempts to access a memory page that is not currently in RAM, a page fault occurs which brings the required page into memory from disk. Page replacement algorithms like FIFO and LRU are used to determine which page to remove from RAM to make room for the new page. If page faults occur too frequently due to insufficient free memory, it can cause thrashing which degrades system performance.

The document summarizes key concepts from Chapter 8 of William Stallings' Computer Organization and Architecture textbook. It discusses the objectives and functions of operating systems, including convenience, efficiency, and acting as a resource manager. It describes different types of operating systems and early batch processing systems. It also provides overviews of memory management techniques like paging, segmentation, virtual memory, and demand paging. Process scheduling and different approaches to memory allocation are summarized as well.
Virtual memory allows for larger logical address spaces than physical memory by storing portions of programs and data on disk when not actively in use. Demand paging loads pages into memory only when accessed, reducing memory usage. When a page fault occurs and no frames are free, page replacement algorithms select a victim page to swap out based on policies like FIFO, LRU, or optimal. File systems organize data on storage using structures like directories with file attributes, allocation methods like contiguous or chained, and access methods like sequential or direct.
This document discusses memory management and implementation issues related to segmentation and paging. It covers the role of the memory manager in allocating and managing memory, early approaches without memory abstractions, and later approaches using segmentation and paging. Key aspects covered include page fault handling, instruction backup after a fault, locking pages in memory, and policies around local vs global page replacement.
A demand-paging system is similar to a paging system, discussed earlier, with a little difference that it uses - swapping.
Processes reside on secondary memory (which is usually a disk).
When we want to execute a process, we swap it into memory.
Rather than swapping the entire process into memory, however, we use a lazy swapper, which swaps a page into memory only when that page is needed.
Since we are now viewing a process as a sequence of pages, rather than one large contiguous address space, the use of the term swap will not technically correct.
A swapper manipulates entire processes, whereas a pager is concerned with the individual pages of a process.
We shall thus use the term pager, rather than swapper, in connection with demand paging.
This document discusses virtual memory and demand paging. It begins with background on virtual memory, how it allows programs to be larger than physical memory. It then discusses demand paging specifically, how pages are brought into memory only when needed by a reference. It describes how page tables track valid/invalid pages and cause page faults when an invalid page is accessed. It also discusses page replacement algorithms which select a page to remove from memory when a new page is needed but no frame is available.
This document provides an overview of memory management concepts including swapping, paging, virtual memory, hardware components like TLB and MMU, and software policies implemented by the operating system. It discusses key topics like locality of reference, thrashing problem, working set model, replacement policy, placement policy, scan rate policy, and fetch policy. The document explains these concepts through examples and diagrams to help the reader understand how memory is managed both in hardware and software.
This document discusses memory management techniques including paging, segmentation, and page replacement algorithms. It begins with an overview of memory hierarchy and basic memory management. It then covers topics such as swapping, virtual memory, page tables, TLBs, page replacement algorithms like FIFO, LRU and clock, and design issues for paging systems including page size and locality. The document also discusses segmentation, its implementation, and examples like MULTICS and the Pentium that use both paging and segmentation.
Memory management is the process of controlling and coordinating a computer's main memory. It ensures that blocks of memory space are properly managed and allocated so the operating system (OS), applications and other running processes have the memory they need to carry out their operations.
Memory management in operating system | Paging | Virtual memoryShivam Mitra
This document discusses memory management techniques in operating systems. It begins by covering contiguous memory allocation approaches like fixed and variable partitioning. It then discusses non-contiguous techniques like paging and segmentation. Key concepts covered include logical vs physical addresses, page tables, translation lookaside buffers, demand paging, and virtual memory. The document provides examples and links to detailed video explanations of these important OS memory management topics.
The document discusses memory management requirements and techniques. The principal responsibilities of memory management are to bring processes into memory for processor execution to ensure sufficient ready processes, and to handle the movement of information between logical and physical memory levels on behalf of the programmer. Memory can be partitioned using fixed, dynamic, or buddy system approaches. Paging and segmentation divide processes into uniform and variable sized chunks respectively and use address translation via tables to map virtual to physical addresses during relocation.
Virtual memory is a memory management technique that uses secondary storage like hard disks to simulate a larger main memory for a process. It allows processes to have a larger address space than the actual physical memory size by swapping pages between main memory and secondary storage. This helps simplify memory management, protect processes from each other, and allows the operating system to share main memory among multiple processes. Virtual memory uses a memory hierarchy with different storage levels having varying sizes and speeds, and implements paging to map virtual addresses to physical addresses through page tables.
This document provides an overview of memory management techniques in operating systems. It discusses the basic requirements of memory management including relocation, protection, sharing, and logical/physical organization. It then describes different partitioning approaches like fixed, dynamic, and buddy systems. Next, it covers paging which divides memory into equal-sized pages and processes into pages, requiring page tables. Finally, it discusses segmentation which divides programs into variable-length segments addressed by segment number and offset.

HCL Notes und Domino Lizenzkostenreduzierung in der Welt von DLAUpanagenda
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-und-domino-lizenzkostenreduzierung-in-der-welt-von-dlau/

2. Hardware and Control
Structures
• Memory references are dynamically translated
into physical addresses at run time
– A process may be swapped in and out of main
memory such that it occupies different regions
• A process may be broken up into pieces that
do not need to located contiguously in main
memory
• All pieces of a process do not need to be
loaded in main memory during execution
2
3. Execution of a Program
• Operating system brings into main
memory a few pieces of the program
• Resident set - portion of process that is
in main memory
• An interrupt is generated when an
address is needed that is not in main
memory
• Operating system places the process in a
blocking state
3
4. Execution of a Program
• Piece of process that contains the logical
address is brought into main memory
– Operating system issues a disk I/O Read
request
– Another process is dispatched to run while
the disk I/O takes place
– An interrupt is issued when disk I/O
complete which causes the operating system
to place the affected process in the Ready
state
4
5. Advantages of
Breaking up a Process
• More processes may be maintained in
main memory
– Only load in some of the pieces of each
process
– With so many processes in main memory, it
is very likely a process will be in the Ready
state at any particular time
• A process may be larger than all of main
memory
5
6. Types of Memory
• Real memory
– Main memory
• Virtual memory
– Memory on disk
– Allows for effective multiprogramming and
relieves the user of tight constraints of main
memory
6
7. Thrashing
• Swapping out a piece of a process just
before that piece is needed
• The processor spends most of its time
swapping pieces rather than executing
user instructions
7
8. Principle of Locality
• Program and data references within a
process tend to cluster
• Only a few pieces of a process will be
needed over a short period of time
• Possible to make intelligent guesses
about which pieces will be needed in the
future
• This suggests that virtual memory may
work efficiently
8
9. Support Needed for
Virtual Memory
• Hardware must support paging and
segmentation
• Operating system must be able to
management the movement of pages
and/or segments between secondary
memory and main memory
9
10. Paging
• Each process has its own page table
• Each page table entry contains the frame
number of the corresponding page in
main memory
• A bit is needed to indicate whether the
page is in main memory or not
10
12. Modify Bit in
Page Table
• Modify bit is needed to indicate if the
page has been altered since it was last
loaded into main memory
• If no change has been made, the page
does not have to be written to the disk
when it needs to be swapped out
12
15. Page Tables
• The entire page table may take up too
much main memory
• Page tables are also stored in virtual
memory
• When a process is running, part of its
page table is in main memory
15
16. Inverted Page Table
• Used on PowerPC, UltraSPARC, and
IA-64 architecture
• Page number portion of a virtual address
is mapped into a hash value
• Hash value points to inverted page table
• Fixed proportion of real memory is
required for the tables regardless of the
number of processes
16
17. Inverted Page Table
• Page number
• Process identifier
• Control bits
• Chain pointer
17
19. Translation Lookaside Buffer
• Each virtual memory reference can
cause two physical memory accesses
– One to fetch the page table
– One to fetch the data
• To overcome this problem a high-speed
cache is set up for page table entries
– Called a Translation Lookaside Buffer
(TLB)
19
21. Translation Lookaside Buffer
• Given a virtual address, processor
examines the TLB
• If page table entry is present (TLB hit),
the frame number is retrieved and the
real address is formed
• If page table entry is not found in the
TLB (TLB miss), the page number is
used to index the process page table
21
22. Translation Lookaside Buffer
• First checks if page is already in main
memory
– If not in main memory a page fault is issued
• The TLB is updated to include the new
page entry
22
27. Page Size
• Smaller page size, less amount of internal
fragmentation
• Smaller page size, more pages required per
process
• More pages per process means larger page
tables
• Larger page tables means large portion of page
tables in virtual memory
• Secondary memory is designed to efficiently
transfer large blocks of data so a large page
size is better
27
28. Page Size
• Small page size, large number of pages
will be found in main memory
• As time goes on during execution, the
pages in memory will all contain
portions of the process near recent
references. Page faults low.
• Increased page size causes pages to
contain locations further from any recent
reference. Page faults rise.
28
31. Segmentation
• May be unequal, dynamic size
• Simplifies handling of growing data
structures
• Allows programs to be altered and
recompiled independently
• Lends itself to sharing data among
processes
• Lends itself to protection
31
32. Segment Tables
• Corresponding segment in main memory
• Each entry contains the length of the
segment
• A bit is needed to determine if segment
is already in main memory
• Another bit is needed to determine if the
segment has been modified since it was
loaded in main memory
32
35. Combined Paging and
Segmentation
• Paging is transparent to the programmer
• Segmentation is visible to the
programmer
• Each segment is broken into fixed-size
pages
35
39. Fetch Policy
• Fetch Policy
– Determines when a page should be brought
into memory
– Demand paging only brings pages into main
memory when a reference is made to a
location on the page
• Many page faults when process first started
– Prepaging brings in more pages than needed
• More efficient to bring in pages that reside
contiguously on the disk
39
40. Placement Policy
• Determines where in real memory a
process piece is to reside
• Important in a segmentation system
• Paging or combined paging with
segmentation hardware performs address
translation
40
41. Replacement Policy
• Placement Policy
– Which page is replaced?
– Page removed should be the page least
likely to be referenced in the near future
– Most policies predict the future behavior on
the basis of past behavior
41
42. Replacement Policy
• Frame Locking
– If frame is locked, it may not be replaced
– Kernel of the operating system
– Control structures
– I/O buffers
– Associate a lock bit with each frame
42
43. Basic Replacement
Algorithms
• Optimal policy
– Selects for replacement that page for which
the time to the next reference is the longest
– Impossible to have perfect knowledge of
future events
43
44. Basic Replacement
Algorithms
• Least Recently Used (LRU)
– Replaces the page that has not been
referenced for the longest time
– By the principle of locality, this should be
the page least likely to be referenced in the
near future
– Each page could be tagged with the time of
last reference. This would require a great
deal of overhead.
44
45. Basic Replacement
Algorithms
• First-in, first-out (FIFO)
– Treats page frames allocated to a process as
a circular buffer
– Pages are removed in round-robin style
– Simplest replacement policy to implement
– Page that has been in memory the longest is
replaced
– These pages may be needed again very soon
45
46. Basic Replacement
Algorithms
• Clock Policy
– Additional bit called a use bit
– When a page is first loaded in memory, the use bit
is set to 1
– When the page is referenced, the use bit is set to 1
– When it is time to replace a page, the first frame
encountered with the use bit set to 0 is replaced.
– During the search for replacement, each use bit set
to 1 is changed to 0
46
52. Basic Replacement
Algorithms
• Page Buffering
– Replaced page is added to one of two lists
• Free page list if page has not been modified
• Modified page list
52
53. Resident Set Size
• Fixed-allocation
– Gives a process a fixed number of pages
within which to execute
– When a page fault occurs, one of the pages
of that process must be replaced
• Variable-allocation
– Number of pages allocated to a process
varies over the lifetime of the process
53
54. Fixed Allocation, Local Scope
• Decide ahead of time the amount of
allocation to give a process
• If allocation is too small, there will be a
high page fault rate
• If allocation is too large there will be too
few programs in main memory
54
55. Variable Allocation,
Global Scope
• Easiest to implement
• Adopted by many operating systems
• Operating system keeps list of free
frames
• Free frame is added to resident set of
process when a page fault occurs
• If no free frame, replaces one from
another process
55
56. Variable Allocation,
Local Scope
• When new process added, allocate
number of page frames based on
application type, program request, or
other criteria
• When page fault occurs, select page
from among the resident set of the
process that suffers the fault
• Reevaluate allocation from time to time
56
57. Cleaning Policy
• Demand cleaning
– A page is written out only when it has been
selected for replacement
• Precleaning
– Pages are written out in batches
57
58. Cleaning Policy
• Best approach uses page buffering
– Replaced pages are placed in two lists
• Modified and unmodified
– Pages in the modified list are periodically
written out in batches
– Pages in the unmodified list are either
reclaimed if referenced again or lost when
its frame is assigned to another page
58
59. Load Control
• Determines the number of processes that
will be resident in main memory
• Too few processes, many occasions
when all processes will be blocked and
much time will be spent in swapping
• Too many processes will lead to
thrashing
59
61. Process Suspension
• Lowest priority process
• Faulting process
– This process does not have its working set
in main memory so it will be blocked
anyway
• Last process activated
– This process is least likely to have its
working set resident
61
62. Process Suspension
• Process with smallest resident set
– This process requires the least future effort
to reload
• Largest process
– Obtains the most free frames
• Process with the largest remaining
execution window
62
63. UNIX and Solaris Memory
Management
• Paging System
– Page table
– Disk block descriptor
– Page frame data table
– Swap-use table
