Abstract :
In transmission of massive data, increasing the data size of every DMA can improve the efficiency. A model of mass DMA can be built based on that method. On the other hand, employing reserved memory can obviously decrease the complexity of DMA buffer acquiring. We design a network data acquisition system based on mass DMA. The experiment can verify the validation of those two methods and the proper working of the acquisition system.
