1. In direct memory access transfers the device would send a " request ". 2. In modern terms, this could be compared to direct memory access ( DMA ). 3. On FreeBSD, it is also possible to debug using Firewire direct memory access ( DMA ). 4. The Display List and the display data are written into direct memory access ( DMA ). 5. A bus control signal could put these lines in a tri-state condition to allow direct memory access . 6. For example the " DO Disable " line would tristate the address lines during direct memory access . 7. It offers low latency, high speed, direct memory access connectivity between devices of different instruction set architectures. 8. Others use smart controllers to place the data directly in memory, a concept known as direct memory access . 9. Direct memory access over the 1394 bus from the host to the target allows kernel debugging over FireWire.10. The 6800 had a three-state control that would disable the address bus to allow another device direct memory access .
