2. UDMA - Wikipedia

   en.wikipedia.org/wiki/UDMA

   The Ultra DMA (Ultra Direct Memory Access, UDMA) modes are the fastest methods used to transfer data through the ATA hard disk interface, usually between a computer and an ATA device. UDMA succeeded Single / Multiword DMA as the interface of choice between ATA devices and the computer.

3. WDMA (computer) - Wikipedia

   en.wikipedia.org/wiki/WDMA_(computer)

   The Word DMA (WDMA) interface is a method for transferring data between a computer (through an Advanced Technology Attachment (ATA) controller) and an ATA device; it was the fastest method until Ultra Direct Memory Access (UDMA) was implemented.

4. Direct memory access - Wikipedia

   en.wikipedia.org/wiki/Direct_memory_access

   Direct memory access (DMA) is a feature of computer systems that allows certain hardware subsystems to access main system memory independently of the central processing unit (CPU). [ 1 ] Without DMA, when the CPU is using programmed input/output , it is typically fully occupied for the entire duration of the read or write operation, and is thus ...

5. Graphics address remapping table - Wikipedia

   en.wikipedia.org/wiki/Graphics_address_remapping...

   A GART is used as a means of data exchange between the main memory and video memory through which buffers (i.e. paging/swapping) of textures, polygon meshes and other data are loaded, but can also be used to expand the amount of video memory available for systems with only integrated or shared graphics (i.e. no discrete or inbuilt graphics ...

6. Input–output memory management unit - Wikipedia

   en.wikipedia.org/wiki/Input–output_memory...

   In computing, an input–output memory management unit (IOMMU) is a memory management unit (MMU) connecting a direct-memory-access–capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU -visible virtual addresses to physical addresses , the IOMMU maps device-visible virtual addresses (also called device ...

7. Network interface controller - Wikipedia

   en.wikipedia.org/wiki/Network_interface_controller

   NICs may use one or more of the following techniques to transfer packet data: Programmed input/output, where the CPU moves the data to or from the NIC to memory. Direct memory access (DMA), where a device other than the CPU assumes control of the system bus to move data to or from the NIC to memory. This removes load from the CPU but requires ...

9. Floppy-disk controller - Wikipedia

   en.wikipedia.org/wiki/Floppy-disk_controller

   The IBM PC took a more conventional approach, their adaptor card could support up to four drives; on the PC direct memory access (DMA) to the drives was performed using DMA channel 2 and IRQ 6. The diagram below shows a conventional floppy disk controller which communicates with the CPU via an Industry Standard Architecture (ISA) bus or similar ...
