DMA Controller

DMA control condition (Discuss the function of the DMA controller chip in a computer system?) present is an Abbreviation of direct stemma access, a technique for transferring data from main memory to a device without passing it through the CPU. Computer that has DMA channels conjunction transfer data to and from devices frequently more quickly than computers without a DMA channel can. This is useful for do quick backups and for real-time applications. fairly expansion boards, such as CD-read-only memory cards, are up to(p) of accessing the computers DMA channel.

When you install the board, you must demarcate which DMA channel is to be used, which sometimes involves setting a perspirer or DIP switch. therefore is DMA so important? Because it allows data to read and write radiation diagram the DMA memory without intercession by the CPU.
