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 ...

Direct memory access (DMA) is a means of having a peripheral device control a processor’s memory bus directly. DMA permits the peripheral, such as a UART, to transfer data directly to or from memory ...

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 ...

Regardless of the class of DMA, the same type ofinformation depicted in Table 1 below makes its way into the DMA controller.When the DMA runs in Register Mode, the DMA controller simply uses thevalues ...

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.

QVIP speeds up the initial PCIe set up and reduces the initial simulation runtime required to set up tests targeted towards verification of PCIe controllers with DMA functionality. Initial PCIe link ...

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, ...
