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 ...

In the world of computers, the central processing unit (CPU) is–well–central. Your first computer course probably explained it like the brain of the computer. However, sometimes you can overload that ...

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.

Soon after research was released that BitLocker drives could be decrypted using SSD hardware encryption flaws, Microsoft released a support bulletin describing how to protect BitLocker from 1394 & ...

The PCI Express® Avalon® Memory-Mapped (Avalon-MM) Direct Memory Access (DMA) Reference Design highlights the performance of the Avalon-MM 256-Bit Hard IP for PCI Express IP Core. The design includes ...

This document describes how to set up the DMA (Direct Memory Access) and also gives an outline of the operation and describes the procedures for using a sample program. The features of the operation ...

Transferring large blocks of data within memory as well as to and from peripherals. Direct memory access (DMA) avoids loading the CPU's register with small amounts of data from memory and storing them ...
