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 ...

In the most simple computer system architecture, all control lies with the CPU (Central Processing Unit). This means not only the execution of commands that affect the CPU’s internal register or cache ...

This Application Note explores the implications associated with performing Direct Memory Access (DMA) operations on an ARM multi-core system such as the ARM11 MPCore and Cortex-A9 MPCore. The target ...

The concept of direct-memory access (DMA) isn’t new; for years now, processors and chipset makers have been implementing DMA as part of their efforts to increase system performance. Similarly, ...
