In this paper,two main methods of data transmission in the existing transmission system ZYNQ platform are studied,and a new multi-channel DMA transmission method is proposed.This method adopts the virtual channel design idea and adopts the multi-channel continuous DMA storage+one-time traversal mode to effectively reduce the participation of PS unit in the data moving process in the data moving process in the ZYNQ platform.It greatly improves the storage capacity at both ends of the data receiving and transmitting,and can be used in application scenarios with large data volume or high real-time requirements.
