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. Unfortunately ...
One of those methods is DMA or direct memory access. As the name implies, DMA is the ability for an I/O device to transfer data directly to or from memory. In some cases, it might actually ...
The DMA_CTRL core implements a low-power, single-channel Direct Memory Access (DMA) controller that is used to transfer data across a bus to and from a peripheral device. With the DMA_CTRL, a DMA ...
LeWiz provides a range of direct memory access controllers (DMA) and bus bridge IP cores. These are customizable to user’s SoC or design requirements. 3 classes of DMAs are offered: * ... The Digital ...
which allows Rust drivers to use the C code he maintains for Direct Memory Access (DMA). Hellwig is bothered by having to deal with several programming languages in one project – and wants to ...

DaMAgeCard SD Express card vulnerability leverages the privileged access that PCIe provides — bypasses traditional software-based security mechanismsA critical vulnerability in SD Express memory cards, called DaMAgeCard, has been uncovered, enabling attackers to exploit the PCIe interface for direct access to system memory. Discovered by ...
Christoph Hellwig, maintainer of the Direct Memory Access (DMA) API, was opposed to Rust code in his section on the grounds that a cross-language codebase was painful to maintain. Torvalds ...
