Direct Memory Access
channel for communications between the memory and surrounding devices (Computers)
(direct memory access) (n ) The transfer of data directly into memory without supervision of the processor The data is passed on the bus directly between the memory and another device Contrast with DVMA
Direct Memory Access Allows a device to read/write directly to system memory without using the CPU
General Direct Memory Access
(n ) Direct Memory Access; allows devices on a bus to access memory without requiring intervention by the CPU
Direct Memory Access Direct access to the main memory without intervention by the processor
A means of transferring data between host memory and a peripheral device without requiring the host processor to move the data itself This reduces processor overhead for I/O operations and may reduce contention on the processor bus
Direct Memory Access/Addressing DMA is a method of transferring data from one memory area to another without having to go through the central processing unit Computers with DMA channels can transfer data to and from devices much more quickly than those in which the data path goes through the computer's main processor
direct memory access; a process in which circuits other than the CPU can read from or write to memory without processor intervention
Direct Memory Access A data transfer feature that bypasses a computer's CPU and allows direct communication between a computer and peripheral devices (like printers), and between one peripheral device and another
Direct Memory Access DMA is a method of transferring data from the disk into memory directly In a CP/M system, the BDOS calls the BIOS entry point READ to read a sector from the disk into the currently selected DMA address The DMA address must be the address of a 128-byte buffer in memory, either the default buffer at 0080H in page zero, or a user-assigned buffer in the TPA Similarly, the BDOS calls the BIOS entry point WRITE to write the record at the current DMA address to the disk
direct memory access Transfer of data from a peripheral device, such as a hard disk drive, into memory without that data passing through the microprocessor DMA transfers data into memory at high speeds with no processor overhead
Direct Memory Access A hardware protocol which allows a special controller circuit (DMA controller) to transfer a block of data from a peripheral device's buffer memory directly to main memory without CPU involvement; cf PIO
An I/O technique that uses hardware logic for speeding data into and out of memory from external devices without the need for the processing units to generate addresses for every memory location
Abbreviation for "Direct Memory Access"; "brain surgery"
– Acronym of Direct Memory Access
n Direct Memory Access The ability of an I/O device to write directly to the computer's RAM, bypassing the slow, CPU intensive Port I/O On the PC architecture, DMA channels come in 8 bit and 16 bit varieties Some are prereserved by design (for example, the floppy drives), while others at system configuration time, like for a sound card
(Direct Memory Access) - method by which data is read or written from shared memory by hardware proxy This may be initiated by firmware, or performed automatically
Direct Memory Access: a type of data transfer which does not require the intervention of the main processor
DMA stands for Direct Memory Access A memory copying hardware to move data between memory regions, or an I/O device and a memory region In many cases, DMA is used for moving I/O data In general, DMA has longer setup time than CPU memory copying, but DMA may have larger copying bandwidth
(Direct Memory Access) addressing used by some hardware Your system should have 6 available addresses 00 to 05 No two pieces of hardware can share a DMA channel Most new hardware no longer uses a DMA Microsoft Press's: A channel for direct memory access that does not involve the microprocessor, providing data transfer directly between memory and the disk drive
Direct Memory Access DACK stands for Dma ACKnowledge and DRQ for Dma ReQuest DMA provides direct access to system memory without adding to CPU overhead The DACK and DRQ channels govern that communication
(Direct Memory Access) A technique that some hardware devices use to transfer data to or from memory directly without requiring the involvement of the CPU
