Research and design of multi-channel DMA controller based on AHB protocol
摘要
Abstract
This study proposes a design method for a multi-channel DMA controller based on the AMBA AHB bus protocol.It puts for-ward a relatively complete design scheme for the multi-channel DMA controller,and provides detailed module designs.Through the multi-channel design,channel arbitration enables the two channels with the highest priority to alternately read and write,thereby pre-venting prolonged bus occupation by a single channel that could block other transfers.And resource consumption is reduced through time division multiplexing.Moreover,potential interactions with external devices are considered,improving transmission efficiency while reducing overall resource utilization.关键词
