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 ...

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 ...

In the eighties, computer processors became faster and faster, while memory access times stagnated and hindered additional performance increases. Something had to be done to speed up memory access and ...

A team from the Computer Architecture and Memory Systems Laboratory (CAMEL) at KAIST presented a new compute express link (CXL) solution whose directly accessible, and high-performance memory ...

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 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 ...
