| Abstract: | In high-speed data acquisition systems and high-speed and high-accuracy numerical control systems,two important factors that may influence the performance of the systems are real-time capability and data transferring interfaces that connect systems.The standard Universal Serial Bus(USB),which has many advantages(including the advantage of data transferring) over other buses,is the dominating bus that is currently widely used.The paper focuses on discussing the realization of the realtime USB driver.Firstly,... |
