摘要： 介绍了基于USB2.0总线的高分辨率动态数据采集系统的开发过程，着重阐述了其硬件电路与固件程序的设计。传输接口的主控制器为P89C61X2单片机，实现USB协议及传输接口的控制；USB接口芯片采用ISP1581，其支持DMA传输功能，保证了单片机环境下高速数据交换所必需的高吞吐率。
Abstract: In this paper, the developing about Motion Image Capture System of high resolution based on USB2.0 is introduced.And the designing methods of its hardware circuitry and firmware procedure are discussed in detail. A high-speed USB interface device ISP1581 is used. Operating in split bus mode, ISP1581 has an independent data bus for high-speed DMA interface, which makes it possible for ISP1581 to reach high data throughput when communicating with host computer though P89C61X2 microcontroller is used for realizeing USB protocol.
