High-speed Data Acquisition System Based on TUSB 6020

In modern production,data acquisition as a mean of information acquisition is becoming increasingly important.In order to ensure data acquisition and high-speed data transmission,based on TI's TUSB6020 USB2.0 interface chip,the TI's TMS320C6424 digital signal processor and TUSB6020 USB2.0 interface are adopted to constitute the high-speed data acquisition system.The characteristics and relationship of each system are studied.The experimental results show that the data acquisition and high-speed data transmission are realized under the control of DSP.
