DMAC接口编程方法

Programming's Way of DMAC Interface

DMA传送是一种计算机内存与外设数据交换的重要方式,本文给出一DMAC接口实验,旨在学生学习DMAC接口时,能具体了解DMAC的工作原理及其编程方法.

DMA(Direct Memory Acess) is an important way to exchange data between memory and peripheral equipments in the computer. The article makes out a interface experiment of DMAC. The main idea is to help to understand the principle of DMA transfer and the programming of DMAC, when taking the experiment DMAC.
