摘要
本文介绍了一种基于USB控制器CY7C68013A的数据采集系统的设计方案，重点介绍了USB控制器的配置模式。利用GPIF方式动态配置FPGA，切换至SlaveFIFO方式进行数据采集，并使用块传输类型，保证了数据传输的正确性。同时详细叙述了软硬件实现过程。
This paper introduces a design scheme of data acquisition system based on USB controller CYTC68013A with the emphasis on the introduction of the configuration mode of the USB controller. The GPIF mode is used for dynamically configuring the FPGA, and then, it is switched-over into the SlaveFIFO mode for the data acquisition and the type of block transfer is applied to ensure the correctness of the data transmission. Meanwhile, the implementation procedures of the software and hardware are elaborated in the paper.
