摘要
USB数据传输中最关心的问题就是数据传输的效率和可靠性,如何高效率无间断的进行数据传输在实际应用中十分重要。由于考虑问题的出发点各异,以至于进行高速无间断数据传输的方法有很多。从USB固件编程出发,研究USB高速无间断数据传输的固件编程问题。通过在固件编程中使用乒乓数据传输模式来达到高速无间断的数据传输。经测试表明,通过该方式对固件编程能够提高数据传输效率,同时能够实现大量数据传输时的无间断传输,因此提高了数据传输的可靠性和连续性。
About the data transmission of USB,the most concerned is the efficiency and reliability of data.In practical application,how to efficiently and incessantly transmit the data is very important.Because of the different starting points of concerning issues,there are many methods of the high-speed and incessant data transmission.The firmware programming problems of USB high-speed and incessant data transmission were researched by using the ping-pang data transfer mode in the firmware programming to achieve the high-speed and incessant data transmission.The test showed that the efficiency of data transmission could be improved by this method and a large number of incessant data transmission could be achieved,which increased the reliability and continuity of data transmission.
