基于AHB总线的双通道DMA控制器的系统设计
System design of dual-channel DMA controller based on AHB bus
摘要
Abstract
Direct Memory Access(DMA)is a high-speed and high-efficiency transmission method for a large amount of data transmission between various modules.After the CPU initializes and configures the DMA,the DMA is allowed to occupy the bus as the host,and can directly read and write the data of the peripheral devices and the memory,so as to realize the data transfer between the peripheral devices and the memory,and between the memory and the memory,without the intervention of the CPU.The design liberates the CPU and greatly improves the efficiency of data transmission.This paper aims to realize data transfer between peripherals and memory of the dual-channel DMA controller based on the AHB bus protocol.关键词
