摘　　要：论述了基于USB的DSP核信号数据采集系统通讯接口的设计方法,其中数据采集系统中的USB通讯芯片采用CY7C68001,上位机通讯界面采用Microsoft Visual C++编写,同时采用CPLD很好地解决了各芯片的逻辑问题。实际测试表明利用USB接口提高了数据传输的速率,节省了资源,而且即插即用的方式方便了连接。A design method of USB communication interface based on DSP nuclear signal acquisition system is introduced. The CY7C68001 chip is used in USB communication interface and the programme in PC is compiled with Microsoft Visual C＋＋. In order to solve logic problem between chips, CPLD is adopted in system. It is indicated that using USB interface improves the speed of data transmission and makes the connection convenient with plug and play.
