| Abstract: | The fastest transfer rate of USB3.0 is up to 5Gbps, therefore, to achieve fast and stable transmission of large amounts of data, a high-speed data transmission system was introduced,which regards FPGA as a control core, DDR2 SDRAM for high-speed large-capacity cache, USB3.0 for data communication interface between recorder and computer. By module hardware circuitry and software protocols,it has achieved highly reliable and stable transmission of data, and solved large-capacity data transfer speed bottleneck. The long-term test proved: the interface transfer rate may stably reach to 150M / s, and the data is accurate and reliable, designed to meet the mission requirements. |
