At the core of DMA is the DMA controller: its sole function is to set up data transfers between I/O devices and memory. In essence it functions like the memcpy function we all know and love from C.

Woodcliff Lake, New Jersey — June 19, 2025 — Semiconductor intellectual property core provider CAST has introduced a new direct memory access (DMA) IP core that alleviates a system’s host CPU from the ...

This problem can be fixed by using the ping-pong mode in the DMA controller by switching between data structures for every DMA request. Basically, he’s extending the number of LEDs is just ...

The Arm CoreLink DMA-350 direct memory access (DMA) controller offloads memory movement tasks from the CPU to improve system performance and energy-efficiency. It includes support for scatter gather, ...

For example, the DMA controller might be optimized to transfer a data word on every clock cycle. When there are multiple transfers ongoing in the same direction (e.g., all from internal memory to ...

In a single-core processor, this mode is useful if the DMA controller and the cache access the same data. It's important to test these strategies when all the system peripherals are running. This will ...

Using the DMA controller in the PCIe switch offers an efficient and attractive alternative to implementing multicast with devices available now. IMPLEMENTING MULTICAST USING DMA IN A PCIE SWITCH A ...

Direct Memory Access (DMA) is a controller feature that has been available at least since the original IBM PC. It can be used by hackers to compromise your otherwise very heavily protected computer.
