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 ...

For memory-intensive and high-performance computing, direct memory access (DMA) is indispensable. A typical DMA operation in PCI Express (PCIe) entails the transfer of data from the system memory to ...

A technique using distributed DMA offers upward compatibility for ISA-legacy devices in PCI-bus systems and provides a vast improvement in performance. The ISA bus, introduced in 1981, has had several ...

In this case study, PLDA explains how verification engineers can use Mentor’s Questa Verification IP (QVIP) to improve productivity during the functional verification of PCIe designs with DMA engines.

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.
