What is dynamic address translation? - IBM

    https://www.ibm.com/support/knowledgecenter/zosbasics/com.ibm.zos.zconcepts/zconcepts_85.htm
    Dynamic address translation, or DAT, is the process of translating a virtual address during a storage reference into the corresponding real address. If the virtual address is already in central storage, the DAT process may be accelerated through the use of a translation lookaside buffer.

Configuring Static and Dynamic NAT Simultaneously - Cisco

    https://www.cisco.com/c/en/us/support/docs/ip/network-address-translation-nat/13778-9.html
    Nov 21, 2014 · In some situations, you may find it necessary to configure both static and dynamic Network Address Translation (NAT) commands on a Cisco router. This document explains how you can do this, and gives a sample scenario.

Mechanism: Address Translation

    http://pages.cs.wisc.edu/~remzi/OSTEP/vm-mechanism.pdf
    6 MECHANISM: ADDRESS TRANSLATION ASIDE: SOFTWARE-BASED RELOCATION In the early days, before hardware support arose, some systems per-formed a crude form of relocation purely via software methods. The basic technique is referred to as static relocation, in which a piece of soft- ware known as the loader takes an executable that is about to be run and …

PCI Express Endpoint-DMA Initiator Subsystem

    https://www.xilinx.com/support/documentation/application_notes/xapp1171-pcie-central-dma-subsystem.pdf
    The subsystem can also perform dynamic address translation between the 64-bit address space of a host device and the 32-bit address space of the AXI Interconnect internal to the FPGA. To facilitate dynamic address translation during DMA Scatter Gather operations, a Translation BRAM was added to the subsystem and can be used to temporarily store ...

Last Class: Memory Management Today: Relocation & Paging

    http://lass.cs.umass.edu/~shenoy/courses/fall12/lectures/Lec12.pdf
    Paging Hardware • Paging is a form of dynamic relocation, where each virtual address is bound by the paging hardware to a physical address. • Think of the page table as a set of relocation registers, one for each frame. • Mapping is invisible to the process; the OS maintains the mapping and the hardware does the translation.

    Translation Lookaside Buffer (3) • “Hit” on TLB? – address translation is in TLB - real fast • “Miss” on TLB? – must read page table entry from memory – takes time – cpu waits idle until it is done • Just like normal cache, but for address mapping – implemented just like cache – instead of cache line data have physical ...

    May 24, 2010 · In addition, Fermi's hardware address translation unit automatically maps pointer reference (c++) to the correct memory space. My questions, does this mean that I can never know the specific and real memory location of read/write operations in programming time owing to the dynamic address translations?

Virtual memory - Wikipedia

    https://en.wikipedia.org/wiki/Virtual_memory
    Address translation hardware in the CPU, often referred to as a memory management unit (MMU), automatically translates virtual addresses to physical addresses. Software within the operating system may extend these capabilities to provide a virtual address space that can exceed the capacity of real memory and thus reference more memory than is ...

Network address translation - Wikipedia

    https://en.wikipedia.org/wiki/Network_address_translation
    Network address translation (NAT) is a method of remapping one IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. The technique was originally used as a shortcut to avoid the need to readdress every host when a network was moved.
