For those who don't know, DMA stands for Direct Memory Access, and it refers to logic circuits in a computer that allow for the automated transfer of system memory to and from peripherals. DMAs are beneficial because they are simple circuits that do work in parallel to the CPU -- while a DMA transfers data, the CPU is free to do other work.that requires more complex computations and logic. The end result is better utilization of the computer's maximum memory transfer bandwidth and computational/logical ability. | For those who don't know, DMA stands for Direct Memory Access, and it refers to logic circuits in a computer that allow for the automated transfer of system memory to and from peripherals.
