Per explanation at Talk:Graphics address remapping table#Page title, "address" seems to be the most common acronym expansion, but also kept "aperture", which is used too. Avoid claims that GART was created by AMD, per sources given on talk page. |

The '''graphics address remapping table'''<ref>{{Cite book|url=http://esd.cs.ucr.edu/webres/agp20.pdf|title=Accelerated Graphics Port Interface Specification: Revision 2.0|date=4 May 1998|pages=24}}</ref> or '''graphics aperture remapping table'''<ref>{{Cite book|url=http://www.playtool.com/pages/agpcompat/agp30.pdf|title=AGP V3.0 Interface Specification|date=September 2002|pages=116}}</ref> ('''GART'''), sometimes also '''graphics translation table''' ('''GTT'''),<ref>{{cite web|author=freedesktop.org|url=http://dri.freedesktop.org/wiki/GART|title=GART|accessdate=2010-03-05}}</ref> is an [[IOMMU|I/O memory management unit]] (IOMMU) used by [[Accelerated Graphics Port]] (AGP) and [[PCI Express]] (PCIe) [[graphics card]]s. The GART allows the graphics card [[direct memory access]] (DMA) to the host system memory, through which buffers of [[texture mapping|textures]], [[polygon mesh]]es and other data are loaded. [[AMD]] later reused the same mechanism for [[I/O virtualization]] with other peripherals including [[disk controller]]s and [[network adapter]]s.<ref>[https://support.amd.com/TechDocs/48882_IOMMU.pdf AMD I/O Virtualization Technology (IOMMU) Specification, 32-bit to 64-bit Legacy I/O Device Mapping]</ref>
