DMA (Direct Memory Access) frees the CPU from these menial tasks. With DMA, peripheral devices do not have to ask the CPU to fetch some data for them, but can do it themselves.

Implementing direct memory access is straightforward, once you know how it works and how to configure your DMA controller. Here’s a primer on this most efficient means of moving data around in a ...

“Direct memory access” doesn’t mean the device has free reign of system memory. I mean, it used to, but that’s like, decades ago now. (It was fun, though, you could do Sneaky Things).

The Direct Access File System (DAFS) is a developing protocol for storing and accessing files. Under DAFS, data is transferred directly from storage to client as logical files, not physical ...

Last time, in Part 1, we introduced somebasics behind Direct Memory Access (DMA) -why it's needed, and how it's structured and controlled. This time,we'll focus on the classifications of DMA transfers ...
