Design of High-Speed Data Transmission System Based on USB 3.0

The development of high-speed and high-precision ADC promotes the development process of waveform digitization in nuclear physics, which in turn brings the digitization process forward. Waveform digitizer preserves the complete pulse waveform data for reconstruction, placing greater demands on data transmission speed. This article introduces an optimized data transmission implementation routine based on USB 3.0. A complete USB transmission system design includes USB firmware design, FPGA logic design, and upper USB controller design. The software and hardware of the system are specially designed to realize high-speed bidirectional communication between FPGA and PC. Through actual test, USB 3.0 transmission is high-speed and reliable, which solves a key problem of data transmission and storage of digitizer. This study has promising applications in nuclide measurements.
