Description
technical field [0001] The invention relates to the field of data acquisition, and more specifically, to a data acquisition system based on a USB dedicated high-speed communication architecture. Background technique [0002] With the continuous development of wireless communication systems, data acquisition plays a key role in the verification process. In a sense, the data acquisition system is to collect the data information inside the system, connect with the PC through some interface, and then transmit the collected data to the PC in a certain format, and analyze the original data according to different needs. Perform corresponding calculations and processing to obtain the required data. However, the high-speed wireless communication system has a high data transmission rate and a large amount of redundant data, and the data acquisition system needs a high-efficiency and high-speed data-specific transmission interface. Therefore, the data acquisition system adopts an eff...
