Understanding Direct Memory Access (DMA) by Mansoor M is a document available to read on EtoBox.
Direct memory access (DMA) allows for data to be transferred directly between an I/O device and memory without needing to pass through the CPU. This facilitates faster maximum data transfer rates and allows the CPU to perform other tasks concurrently. Unlike programmed I/O where data passes through the CPU, DMA transfers data directly from memory to memory or between a device and memory. A DMA controller takes over the memory buses to directly manage transfers between devices and memory so the CPU is idle d
