Abstract

With the modern industry´s rapid development, the speed of data information acquisition is needed to increase highly. The speed of data information acquisition system is not only in connection with the factors, such as the performance of CPU, A/D converter, and data processing circuits, but also data information´s transmittal mode. AT89C51 is a kind of high cost performance microprocessor. Depends on AT89C51 and its some interface circuits, the DMA´s control process can be simulated. Because the CPU is not required in the data information transmission, the data information are transmitted to the storage directly, and this can realize the data information´s transmission with high speed. The data information acquisition system may be applied in image processing, disk accessing and some other applications where need high speed and great capacity data transmission.
